If you dont understand something he does a very good job explaining it in understandable terms. Very patient, can solve just about any problem, does a good job with adjusting to a change in meeting times.
I was having trouble grasping some difficult physics concepts. Professor A. easily translated these concepts into terms that I could understand. His mastery of the material and his communication skills make him an excellent tutor. I recommend him to all my friends and anyone reading this testimonial.
After Bill was notified by your company I received a call right away. He was willing to see me the follow day of contact which was great because I was drowning and close to failing my statistics class.
Mr A made statistics easy to learn. He also added helpful side bar examples, etc. Mr A has saved me from a huge failure. Bill has also gone out of his way to accommodate me in a time crutch with mid-term, test, etc. What I've accomplished with Mr A is worth far more than an hourly salary. I would recommend him to other students, friends, etc. I have an advance statistics class in the future and would love to work with Mr A again.
I've spent an excellent 2 hours with Dr William. We talked about the course outline and spent time reviewing some courses and exercise. Dr William also spoke extensively about different strategies to pass the GRE Physics subject test, and the courses required. I think the first session was very helpful and a very good start.
William A is very helpful in explaning algebra operations. After my first tutoring session with William A I was able to complete algebra equations on my own. If he can help me when I am adult in my forty's attending college, I know he can help you. Just listen to him and study.
In most cases, tutors gain approval in a subject by passing a proficiency exam. For some subject areas, like music and art, tutors submit written requests to demonstrate their proficiency to potential students. If a tutor is interested but not yet approved in a subject, the subject will appear in non-bold font. Tutors need to be approved in a subject prior to beginning lessons.
The ACT Mathematics Test is a 60-question, 60-minute test designed to measure the mathematical skills that students have typically acquired by the end of 11th grade. The test presents multiple-choice questions that require one to use reasoning skills to solve practical problems in mathematics. You aren't required to know complex formulas and perform extensive computation, but you do need knowledge of basic formulas and computational skills to answer the problems. All of the problems can be solved without a calculator.
I took this test during High School and found the mathematics, while challenging, to be quite tractable. Preparing for this test should put you in quite good shape.
Note: unless otherwise stated on the test, one should assume that:
1. Figures accompanying questions are not drawn to scale.
2. Geometric figures exist in a plane.
3. When given in a question, “line” refers to a straight line.
4. When given in a question, “average” refers to the arithmetic mean.
The format of the ACT Math Test is straightforward; ACT simply lumps all of the problems into one big list of math questions. There are two types of questions: basic problems and word problems. Word problems tend to be more difficult than basic problems simply because they require the additional step of translating the words into a numerical problem that you can solve. Of course, a basic problem on a complex topic will still likely be more difficult than a word problem on a very easy topic.
Content that could appear on the ACT Mathematics Test. In the Mathematics Test, three sub-scores are based on six content areas as follows:
• Pre-Algebra (23%). basic operations using whole numbers, multiples & primes, decimals, fractions, and integers; divisibility, remainders and place value; square roots and approximations; the concept of exponents; scientific notation; factors; ratio, proportion, and percent; number problems, linear equations in one variable; absolute value and ordering numbers by value; elementary counting techniques and simple probability; series, data collection, representation, and interpretation; mean, median, & mode and understanding simple descriptive statistics.
• Elementary Algebra (17%). properties of exponents and roots, evaluation of algebraic expressions through substitution, using variables to express functional relationships, understanding algebraic operations, writing expressions & equations, simplifying algebraic expressions, multiplying binomials and the solution of quadratic equations by factoring.
Intermediate Algebra/Coordinate Geometry
• Intermediate Algebra (15%). Relationship between sides of an equation, an understanding of the quadratic formula, rational and radical expressions, logarithms, absolute value equations and inequalities, sequences and patterns, systems of equations, quadratic inequalities, functions, modeling, matrices, roots of polynomials, and complex numbers
• Coordinate Geometry (15%). graphing and the relations between equations and graphs, number lines & inequalities; the (x,y) coordinate plane including points, lines, polynomials, circles, and other curves; graphing inequalities; slope; parallel and perpendicular lines; distance; midpoints; and conics.
• Plane Geometry (23%). the properties and relations of plane figures, including angles and relations among perpendicular and parallel lines; properties of circles, triangles, rectangles, parallelograms, trapezoids and polygons; transformations; the concept of proof and proof techniques; volume; and applications of geometry to three dimensions.
• Trigonometry (7%). understanding trigonometric relations in right triangles; values and properties of trigonometric functions (SOHCAHTOA); solving triangles; graphing trigonometric functions; modeling using trigonometric functions; use of trigonometric identities; and solving trigonometric equations.
Calculators may be used for any problem on the test, but could be more harm than help for some questions. You are responsible for knowing if your calculator model is permitted. If the test staff finds that you are using a prohibited calculator or are using a calculator on any test other than the Mathematics Test, you will be dismissed and your answer document will not be scored.
In terms of time allotted per question, the Math Test ranks the highest among the subject tests, averaging one minute per question. The drawback is that the Math Test is relatively difficult for most people. It tests learned knowledge, not just intuitive knowledge.
The ACT Science Test is a 40-question, 35-minute test that measures the skills required in the natural sciences: interpretation, analysis, evaluation, reasoning, and problem solving. The test assumes that students are in the process of taking the core science course of study (three years or more) that will prepare them for college-level work and have completed a course in Earth science and/or physical science and a course in biology.
I took the ACT Science Test in High School and scored quite well. Using this material to prepare will put you in good shape and allay many of your fears.
The test presents seven sets of scientific information, each followed by a number of multiple-choice test questions in one of three different formats:
• 3 Data Representation (38%). This format presents graphic and tabular material similar to that found in science journals and texts. The questions associated with this format measure skills such as graph reading, interpretation of scatterplots, and interpretation of information presented in tables, diagrams, and figures. (5 questions each)
• 3 Research Summaries (45%). This format provides descriptions of one or more related experiments. The questions focus on the design of experiments and the interpretation of experimental results. (6 questions each)
• 1 Conflicting Viewpoints (17%). This format presents expressions of several hypotheses or views that, being based on differing premises or on incomplete data, are inconsistent with one another. The questions focus on the understanding, analysis, and comparison of alternative viewpoints or hypotheses. ( 7 questions each)
The questions require you to:
• recognize and understand the basic features of, and concepts related to, the provided information
• examine critically the relationship between the information provided and the conclusions drawn or hypotheses developed
• generalize from given information and draw conclusions, gain new information, or make predictions.
These seven passages appear in no particular order on the Science Reasoning Test. Each passage will be preceded by a written introduction to, or explanation of, the presented data. There is no standard appearance for the passages, but they all follow the basic principle of providing graphic information in addition to written exposition.
Within the total allotted time for the subject test, you may spend as much time as you wish on each individual passage. Calculator use is not permitted; There is absolutely no need for a calculator on this test, so it doesn’t matter that you’re not allowed to use one. Answer every question. Your scores on the multiple-choice tests are based on the number of questions you answer correctly. There is no penalty for guessing.
The content of the Science Test includes biology, chemistry, physics, and the Earth/space sciences (for example, geology, astronomy, and meteorology). Advanced knowledge in these subjects is not required, but background knowledge acquired in general, introductory science courses is needed to answer some of the questions. The test emphasizes scientific reasoning skills over recall of scientific content, skill in mathematics, or reading ability.
The four main kinds of questions you’ll encounter on the Data Representation and Research Summaries passages will ask you to:
• Read the Chart. These questions ask you simply to identify information given on the chart.
• Use the Chart. Slightly more complicated than Read the Chart questions, these questions require that you use the information given in the chart to determine other, unstated information.
• Handle Graphs. For these questions, you will either have to translate the information in the charts into words or translate words or numbers into a chart.
• Take the Next Step. These questions ask you what the next step should be for research experiments.
The questions on the Conflicting Viewpoints section are slightly different with three main categories; detail, inference, and comparison.
• Detail questions ask you to identify specific information from the arguments presented.
• Inference questions ask you to draw out implied information from the arguments.
• Comparison questions ask you to find and analyze similarities and differences between the arguments.
The ACT Science Reasoning Test is arguably the most feared Subject Test, but for the wrong reasons. Time is of the essence on the test: you are given 35 minutes to digest 7 science passages and answer 40 questions on them. But the content of the Science Reasoning test, which is what usually fills students with trepidation, shouldn’t cause any stress. The term “Science Reasoning” may sound impressive and difficult, but much of the intimidation of the test is mere bluff—big words that disguise rather simple concepts.
Algebra is our introduction to that branch of mathematics that substitutes letters for numbers. An algebraic equation represents a balance scale; what is done on one side of the scale with a number is also done to the other side of the scale. The numbers are the constants. Algebra can include real numbers, complex numbers, matrices, vectors, etc.
Here in Algebra 1, we will work on the basics of algebraic concepts including;
• Slope of a straight line
• Exponents and Exponential Decay
• Fraction equations
• Linear Equations and Inequalities
• Parabolas and Quadratic Equations
• Percent, Ratios and Proportions
Also included are multiplying polynomials, the Distributive property for simplifying monomial expressions, the Symmetric Property of Equality (If a = b then b = a), how to solve Word Problems and problems involving distance, rate (speed) and time.

• Permutations and combinations.
• Mathematical modeling of real life applications.
There are certain subjects, like Astronomy, that study not only “the world”, actually “The Universe”, in which we live, they also invoke spectacular imaginations to students of all levels. I feel very much the same sort of awe; from the books and toy telescopes that I received as a child, to the telescopes and space programs I work on today. Having worked on missions such as the NEAR-Shoemaker Asteroid Rendezvous for The Johns Hopkins University and the Mars Observer for RCA, I feel that my perspective is somewhat uniquely qualified by my own personal experiences and achievements. Being a physicist certainly helps as well.

The Armed Services Vocational Aptitude Battery (ASVAB) is a multiple-aptitude battery that measures developed abilities and helps predict future academic and occupational success in the military. It is administered annually to more than one million military applicants, high school, and post-secondary students.
Having personally taken this test and scoring quite well, I can easily speak from experience.
Paper and Pencil Administration (MET sites)
The total time required, including administrative tasks and instructions, is three to four hours. When you complete the items in a subtest, you may review your answers. After the test session, answer sheets are sent to the MEPS to be scanned and scored. This process usually takes a few days.
Computer Administration (MEPS sites)
The computer version of the ASVAB, called the CAT-ASVAB, is an adaptive test. This means that the test adapts to the ability level of each individual examinee. Thus, it is possible to administer a shorter test than is used in the paper and pencil administration. There are time limits imposed on each subtest in the CAT-ASVAB, but almost all examinees complete the individual subtests before the time expires. On average, it takes about 1½ hours to complete the CAT-ASVAB. Your test scores will be available immediately after the test session.
Scores on the individual ASVAB subtests are reported as Standard Scores. Standard Scores are scores that have a meaning relative to a national sample of youth aged 18 to 23. About half the population scores at or above a Standard Score of 50 and about 16% of the population scores at or above a Standard Score of 60.
Preparing for the ASVAB
The following are general tips to help you to perform your best on the ASVAB.
Steps to Take In Advance of the Actual Test Day
• Prepare well in advance of the day of the test.
• Know what to expect on test day.
• Familiarize yourself with the contents of the ASVAB subtests.
• Take sample questions and review content areas in which you need to freshen up your skills.
• Find out whether you will be taking the paper and pencil (P&P) ASVAB, or the CAT-ASVAB, as optimal test-taking strategies differ across the two versions.
• Get plenty of rest the night before the test.
Strategies For Taking Both Versions of the ASVAB
• Pay attention to the time — don’t spend too much time on one individual question, if that means you won’t have time to answer later questions.
• When you don’t know the answer to a question, try to rule out as many incorrect choices as you can, and then make an educated guess from the remaining answers.
Strategies For Taking the P&P ASVAB
• Don’t get hung up trying to answer questions you don’t know — answer the questions you do know and return later to the ones you skipped.
• Answer every question. If you run out of time, it is to your advantage to fill in random guesses for the remaining items, as there is no penalty for guessing.
Strategies For Taking the CAT-ASVAB
• Be familiar with how the CAT-ASVAB works.
• If time is running short, try to read and legitimately answer the questions, rather than filling in random guesses for the remaining items, as the CAT-ASVAB applies a relatively large penalty when several incorrect answers are provided toward the end of a subtest.
Taking a test can be a nerve-wracking experience. Knowing what to expect can help to reduce those pre-test jitters.

Biology is the science of life, living and non-“living” organisms, and living matter, in all its forms and phenomena, including its structure, function, growth, origin, evolution, behavior and distribution. It includes Botany, the study of plants; Zoology, the study of animals; and Microbiology, the study of microorganisms and all their subdivisions.
Having a Ph.D. Biologist as my parent has been invaluable in understanding Biology and its principles. Some of my first jobs were as a junior Field Technician doing Biological research for the University of Illinois. My own PhD work, while in microscopy, was heavily influenced by the cells, cancers and microorganisms I was imaging, in addition to the training I received at Illinois in cellular mechanics.
Major topics include; the philosophy of science, scientific method, chemical organization and constituents of life, cell biology, molecular genetics, molecular evolution and biodiversity. An introduction to higher levels of biological organization from the organism to the ecosystem is presented. Additional topics include; organismal structure and physiology, behavior, population ecology, community ecology, ecosystem ecology and environmental biology. This biology material involves the scientific study of living organisms and considers the interactions among the vast number of organisms that inhabit planet Earth. Herein, it presents the basic form and function of these organisms, from cells to organ systems, from simple viruses to complex humans.
More detailed specific topics include; basic chemistry, biomolecules; bioenergetics, kinetics, enzyme catalysis, cellular respiration and metabolism, photosynthesis, nutrients and tropism, DNA structure and replication, protein synthesis, regulation of gene expression, genetic engineering, and cancer. Also available are; gas exchange, translocation mechanisms, circulation, hormones, excitable cells, nerve cell function, muscle cell function, regulation and homeostasis. Cell topics include; differentiation, metamorphosis and regeneration, embryonic development, cell cycles, mitosis and meiosis, Mendelian inheritance, gene expression and gene interactions. Macro-principles include; human inheritance, mechanisms of evolution, natural selection, adaptation, population genetics, speciation, sexuality. Discussed in environmental biology are; the biosphere, communities and community succession, energy and productivity, mineral cycles, community structure, population dynamics, population growth and reproductive strategies, population regulation, human populations and human intrusion in ecosystems.
Biostatistics is a powerful and productive application of statistics to biological systems. Statistics has to do with the collecting and analyzing of numerical data in large quantities. Biology is the science of life, including its structure, function, growth, origin, evolution, behavior and distribution and most biological data has to deal with large numbers. Applications encountered can be anything from the number of Escherichia coli in a set of water samples to deer populations grazing along power lines.
I had a job once with the University of Illinois as a Field Technician on an Environmental Impact Study. The work entailed collecting and processing soil samples that contained ground mites and then counting the various microscopic mite distributions to see if there was any difference between our test and control sites. What we were looking for was any manifestation of statistical differences between the test and control population distributions. You may also wish to see my WyzAnt certifications for statistics (and probability) and biology along with their subject descriptions and my general profile for more information.
Here in calculus, we examine the key concepts of the limit, the derivative, and continuity, as well as their main applications in graphing and optimizing functions. From there, we will go on to explore the fundamental theorem of calculus, which leads to the concept of integration and integrals, and eventually study polynomial approximations and series. Logarithmic, exponential, and other transcendental functions are included.
My experience with differential and integral calculus covers undergraduate Calculus I, II and III, and extends well into their advanced applications, some of which I inevitably used in my doctoral research. Throughout my collegiate education, I have always come across some idea or technique associated with integral or differential calculus and used many of the techniques covered herein in my everyday employment in the aerospace industry.
In this study of calculus, we want to start by fostering an intuitive understanding of the limiting process (including one-sided limits) based upon functions, estimating limits from graphs or tables of data, and calculating limits using algebra. We will also understand asymptotes and unbounded behavior in terms of graphics and describe asymptotic behavior in terms of limits involving infinity. An intuitive understanding of continuity as a property of functions in terms of limits, and the Intermediate Value and Extreme Value theorem are also anticipated.
The concept of the derivative is presented graphically, numerically and analytically and interpreted as an instantaneous rate of change. The derivative is identified as being the slope of a curve at a point, a tangent line to a curve, and a local linear approximation, in addition to being the instantaneous rate of change as the limit of the average rate of change. The derivative is also shown to be a function, and the corresponding characteristics of the graphs of ƒ and ƒ’, the relationship between the increasing and decreasing behavior of ƒ and the sign of ƒ’, the 1st derivative test, Rolle’s theorem and the mean value theorem with their geometric interpretations are examined. Second derivatives, the corresponding characteristics of the graphs of ƒ, ƒ’ and ƒ’’, and the relationship between the concavity of ƒ and the sign of ƒ’ are also demonstrated. Techniques are presented for computation of derivatives of basic functions, including power, exponential, logarithmic, and trigonometric functions, as well as differentiation rules for sums, products and quotients of functions, the chain rule and implicit differentiation. Applications of derivatives including analysis of curves/sketching, the notions of monotonicity and concavity, optimization, modeling rates of change, and interpretation of the derivative as a rate of change are presented as well as L’Hospital’s Rule for determining limits and convergence of improper integrals and series.
Basic properties of definite integrals (including additivity and linearity) with interpretations, the definite integral as a limit of Riemann sums, and the definite integral of the rate of change of a quantity over an interval are presented. Use of the Fundamental Theorem of Calculus to unite differential and integral calculus, evaluate definite integrals and represent particular antiderivatives is demonstrated. Techniques of antidifferentiation, including antiderivatives following directly from derivatives of basic functions, antiderivatives by substitution of variables parts, simple partial fractions, improper integrals, indefinite integration, and calculating volumes through solids of revolution are shown. Applications of antidifferentiation, including the finding of specific antiderivatives using initial conditions, motion along a line, solving separable differential equations, use in modeling, as well as Riemann and trapezoidal sums to numerically approximate definite integrals are presented.
The concept of series as a sequence of partial sums and convergence is defined in terms of the limit of partial sums. Series of constants forming a geometric series (with applications), the harmonic series, terms of series as areas of rectangles, their relationship to improper integrals, and the ratio test for convergence and divergence are shown. Taylor polynomial approximation with graphical demonstration of convergence, Maclaurin series for various functions, the general Taylor series centered at x = a, and power series functions are defined. The natural logarithmic function, inverse functions, exponential functions their differentiation and integration, differential equations for growth and decay and other transcendental functions are included as necessary.

Discrete mathematics is the branch of mathematics dealing with objects that can assume only distinct, separated values. Often called ‘Everything except calculus,’ the term “discrete mathematics” is therefore used in contrast with “continuous mathematics,” which is the branch of mathematics dealing with objects that can vary smoothly.
From my 25 years in the aerospace electronics industry, I have been fortunate to have used the following discrete mathematics techniques in my career, namely:
Having worked extensively with the design and production of microcircuits, I’ve used boolean algebra (a “Discrete Algebra”) and logic extensively for understanding digital gates and programming. My work with large databases acquainted me with relational algebras and I’ve used linear algebra (matrices and arrays) in situations such as image processing and mechanics.
As a Reliability Engineer for complex space electronic systems, I developed an in-depth understanding of Combinatorics (permutation, combination and partitioning) and calculation of probabilities in order to produce failure rates, Mean-Time Between Failures (MTBF) and to conduct Failure Modes, Effects and Criticality Analyses (FMECA).
As a Systems Engineer, I’ve used Program Evaluation and Review Technique (PERT) and Operations Management Theory, including Gantt chart analyses and Linear Programming, to model many cost and schedule relations and process dynamics for Highly-Capable/Highly-Reliable aerospace programs. This required a sophisticated understanding and implementation of Graph and Network Theory. The largest cost account that I defined and managed was $13.4m in Labor and Material.
As a Technical Entrepreneur, I’ve performed Strategic Marketing Analyses which requires a visceral understanding of Utility Theory in order to evaluate quantitative measures of the relative economic satisfaction from the consumption of various goods and services.
I am more than happy to share these practical applications of Discrete Mathematics, and the theory behind them, with my students.
Electrical engineering deals with the practical application of the theory of electric and magnetic forces and their effects on the design and construction of machinery, especially the design and application of circuitry and equipment for power generation and distribution, machine control, and communications.
Having worked in aerospace electronics for over 20 years, I have the following industry experience that is readily transferable to my students:

Geometry describes mathematically the properties, measurement, and relationships of points, segments, lines, angles, surfaces, triangles, polygons, circles and solids. Through their introduction, the student develops an understanding of the theorems and postulates that form the foundation of geometry. The concepts of Euclidean geometry are stressed through definitions and deductive proofs.
Emphasis is placed on the description and use of inductive, deductive, and intuitive reasoning skills. Geometry is studied as a mathematical system through the deductive development of relationships in the plane and space developed intuitively in previous years. Powers of abstract reasoning, spatial visualization and logical reasoning patterns are improved through this study. The focus is on comparisons between these objects concerning surface areas, volumes, congruency, similarity, transformations, and coordinate geometry.
The structures studied include congruent segments and angles, circle chords, secants and tangent segments, parallel and perpendicular lines, angle measure in triangles, direct and indirect triangle congruence and similarity, proofs, solids of revolution, logic, similar triangles, transformations, the Pythagorean Theorem, geometric constructions, coordinate geometry, and surface area and volume of solids. This includes the study of transformations and right triangle trigonometry. Inductive and deductive thinking skills are used in problem solving situations, and applications to the real world are stressed. Also emphasized is writing proofs to solve (prove) properties of geometric figures. Algebra I skills are used throughout.

• In this section, you may use the on-screen calculator.
• Quantitative Reasoning scores are reported on a 130 — 170 score scale, in 1-point increments.
The Analytical Writing section measures your critical thinking and analytical writing skills, specifically the ability to articulate complex ideas clearly and effectively:
• For each essay task, you are given a topic and specific directions for responding to that topic.
• Your responses will be evaluated on whether you can integrate critical thinking and analytical writing by fully addressing the tasks you're presented.
• Analytical Writing scores are reported on a 0 — 6 score scale, in half-point increments.
There are three ways for you to receive your scores:
• View your scores online
• Get your scores in the mail — Your official score report will be sent to you in the mail after your test is scored.
• Hear scores over the phone — You can receive your scores by phone for a small fee
In addition to your scores for each section, your report will include your name, contact information, intended major, score recipients, test dates and percentile rank information. Scores for the computer-based GRE revised General Test are reported 10 — 15 days after your test date:
• GRE score reporting is cumulative and good for five years. That is, if you have taken one or more tests within the five-year period prior to the current testing year (July 1 — June 30) all scores earned during that period will be reported.
• Your score report will include the names of all the schools you're sending scores to, plus your cumulative record reported at that time.
ETS is committed to serving test takers with disabilities and health-related needs by providing services and reasonable accommodations that are appropriate given the purpose of the test.
Linear algebra is the branch of mathematics that is concerned with mathematical structures such as matrices and determinants. This includes the theory of systems of linear equations, vector spaces, and their transformation properties. The structures are called “closed” under the operations of addition and scalar multiplication because using these two operations on these structures simply results in a similar structure. Linear algebra allows the analysis of rotations in space, least squares fitting, solution of coupled differential equations, analytic geometry, as well as many other problems in mathematics, physics, and engineering.
I have had extensive experience using, teaching and training in linear algebra throughout my career in areas ranging from electrical engineering, computer science and practical mathematics applications, to advanced mechanics, numerical methods and group theory. I’ve taught basic linear algebra in order to deal with the geometries for classical mechanics and linear system techniques used for Kirchhoff’s Equations in circuit analysis. My doctorate involved the digital acquisition and fast Fourier transformation of large video arrays involved in image processing. My graduate studies at The Johns Hopkins University included readings and lessons out of Arfken’s, Mathematical Methods for Physicists, and Goldstein’s Classical Mechanics.

Microsoft Excel is an electronic spreadsheet program whose options for manipulating numbers have made it the most popular spreadsheet program in the world. Its widespread use makes it easy to exchange files with almost anyone, or to display information in printed form.
Having used Excel extensively, I can attest to its superiority over the competition. I find Excel to be 99% intuitive in getting me what I want.

Microsoft Excel has the basic features of all spreadsheets, using a grid of cells arranged in numbered rows and letter-named columns to organize data manipulations like arithmetic operations. It has a battery of supplied functions to answer statistical, engineering and financial needs. In addition, it can display data as line graphs, histograms and charts, and with a very limited three-dimensional graphical display.
Excel supports charts, graphs or histograms generated from specified groups of cells. The generated graphic component can either be embedded within the current sheet, or added as a separate object. These displays are dynamically updated if the content of cells changes. For example, suppose that the important design requirements are displayed visually; then, in response to a user's change in trial values for parameters, the curves describing the design change shape and their points of intersection shift, assisting the selection of the best design.
Because it is part of the Microsoft Office Suite, Excel can easily exchange data with that suite's database, word processing and presentation program. Excel features calculation and graphing tools that have almost completely replaced Lotus 1-2-3 as the industry standard for spreadsheets. The current versions are 2010 for Microsoft Windows and 2011 for Mac OS X.

The definition of what constitutes Physical Science may change from program to program; often consisting of just (some) chemistry and (some) physics.
I prefer a broader definition such as;
"Physical Science includes astronomy, atmospheric science, chemistry, geology, physical geography and physics."
Significant themes include the Scientific Method, Scientific Measurements and Tools of Science.
An introduction to Astronomy is treated as a broad survey of modern astronomy examining the solar and stellar systems, an overview of the structure and motion of comets, asteroids, the planets and their natural satellites, and an examination of our present understanding of the nature, origin and evolution of the sun, stars, galaxies, and special objects. Opportunities include learning about lenses and mirrors, construction and use of telescopes, how to make measurements, and how to read star charts and locate objects in the heavens.
Atmospheric Science is an introductory examination of the Earth's weather and climate. This segment covers a broad range of topics including the origin, composition, and structure of the atmosphere; the formation of clouds and precipitation; the formation of organized weather systems; weather prediction; air pollution; and climates.
The foundations of Chemistry segment addresses matter, its composition and the changes it undergoes. This segment also examines the influence of chemistry on society through studies on topical subject areas in chemistry such as energy, environmental and health issues. This material provides a broad background in general chemical principles including Chemical vs. Physical changes, compounds, formula naming, and fundamental concepts in inorganic chemistry. Atoms, atomic theory and structure, organization of the Periodic Table, and chemical bonding are also presented as well as chemical reactions and their balancing chemical equations. Stoichiometry, gas laws, solutions, equilibria, redox, acid-base theory, pH scale, fundamental concepts in organic chemistry, and nuclear chemistry are also topics.
The focus of the introduction to Geology segment is on the physical composition of the Earth and the dynamic processes that affect it. Topics covered include plate tectonics, mountain building, volcanoes, earthquakes, glaciers, rivers, minerals, and rocks.
Physical Geography is an introduction to the geographical features of the Earth's natural environment. This segment examines the physical, chemical and biological processes that shape these features and control their spatial distribution; the dependence of human society on the natural environment; and the ways in which humans intentionally and unintentionally modify the natural environment.
An algebra/trigonometry-based study of Physics includes matter and energy, force and motion, kinematics, Newton's Laws, Universal Gravitation, simple machines, dynamics, momentum, conservation and transformation of energy. Rotational motion, mechanics, and forces in fluids such as Bernoulli's Principle and Archimedes' Principle are presented. Fundamental concepts of the Kinetic Theory dealing with molecular motion and energy, gas laws, stresses and strain in materials and the phases of matter are addressed. Topics include measurement, work, power, heat and heat transfer - conduction, convection, and radiation. Also considered are thermodynamics, waves, sound, light, mirrors and lenses, color, fundamental concepts of static and dynamic electrical charges and their characteristic behavior. Electricity and magnetism, circuits, magnets, computers, and Nuclear Reactions, Decay and Half-Life, Fission and Fusion Reactions, and Issues with Nuclear Energy are covered.
With an understanding of this material, students should be able to demonstrate an understanding of the physical environment and be able to apply the scientific principles to observations experienced. The role of the student here is to develop inquiry and problem solving skills within the context of scientific investigation. Students will apply what they learn to everyday situations by conducting investigations and formulating and testing their own hypotheses.
Physics (Physics / General Physics) is the branch of science that deals with matter, energy, motion, and force. More specifically, the science of matter and energy, and of their interactions, grouped in traditional fields such as acoustics, optics, mechanics (statics and dynamics), thermodynamics, and electromagnetism, as well as in modern extensions including atomic and nuclear physics, cryogenics, solid-state physics, particle physics, and plasma physics. This material provides a systematic introduction to the main principles of physics and emphasizes the development of conceptual understanding and problem-solving ability using algebra and trigonometry, and calculus when requested.
In any course of instruction that addresses physics, the student is often asked to think and make decisions in ways and situations that they might not have done so previously. This is accomplished by using applied mathematics in accordance with a set of rules, laws and “physical” principles. Providing sufficiently deep insight and coaching successful performance is often left as the responsibility of the physics tutor. In order to hopefully simplify physics instruction, homework and exam questions, many students and instructors categorize physics problems into one of two classes; the conceptual and the solution-oriented. The solution-oriented approach, when necessary, proceeds in a structured, step-wise fashion, i.e., a problem statement, a physical diagram, identified ‘knowns’ and unknowns, selection of governing equations and principles, etc. Step-wise “solution-type” methods are easily taught (and even memorized), and key features are knowing when to use which tool, specific approach or equation. For a conceptual-type problem, the method of solution can often be an “acquired taste,” akin to solving proofs in mathematics, requiring a study of similar situations, and even ‘reflective’ thought.
To meet our student’s needs, this material is an algebra and trigonometry-based study of classical mechanics, [linear and rotational kinematics and dynamics (including work, energy, impulse, momentum, and collisions)], fluids, heat, thermodynamics, periodic motion, wave motion, vibrations and sound, electricity, electrostatics, electric fields, Gauss' law, capacitance, current, resistance, magnetic forces and fields, electromagnetic induction, DC and AC circuits, electromagnetic waves, mirrors, lenses, geometrical optics, and modern physics. Additional topics include vector algebra, motion in a plane, internal energy, gravity, angular momentum, conservation laws, measurement concepts, heat and electrical circuits, relativity, atomic structure, the nucleus, fundamental particles and nuclear physics. When requested, calculus-based topics include dynamics of single and many-particle systems, circular and rigid body motion, elasticity, and the laws of thermodynamics with applications to ideal gases, thermodynamic processes, electromagnetism and optics. Modern physics, based on quantum theory, includes atomic, nuclear, particle, and solid-state studies. Physics also embraces many other applied fields such as geophysics and meteorology.
Algebra is that branch of mathematics that substitutes letters for numbers. An algebraic equation represents a balance scale; what is done on one side of the scale with a number is also done to the other side of the scale. The numbers are the constants. Algebra can include real numbers, complex numbers, matrices, vectors, etc.
Pre-algebra explores mathematical concepts that are foundational for success in algebra including the fundamentals of arithmetic, algebraic expressions, positive and negative integers, rational numbers, equations, decimals, fractions, ratios, proportions, percents, area, volume, and probability. Students will develop and expand problem solving skills (creatively and analytically) in order to solve word problems and continue to practice using math skills to solve word problems and think creatively and analytically.
Pre-algebra introduces beginning topics in number theory and algebra, including common divisors and multiples, primes and prime factorizations, basic equations, expressions and inequalities, ratios, Squares, Cubes, and Higher Exponents, Multiples and Divisibility Tests, Primes and Prime Factorization, Least Common Multiple, Greatest Common Divisor, Advanced Equations and Word Problems, Speed and Rates, Percent Increase and Decrease, Angles and Parallel Lines, Angles and Polygons, Perimeter and Area, Circles, Pythagorean Theorem, Special Triangles and Quadrilaterals, Tables, Graphs, Charts and Counting as Arithmetic.
Pre-algebra includes square roots, a thorough exploration of geometric tools and strategies, an introduction to topics in discrete mathematics and statistics, and a discussion of general problem-solving strategies. After completing pre-algebra, students will be able to:
• evaluate numerical and algebraic expressions using order of operations;
• use basic operations (addition, subtraction, multiplication, division, and absolute value) with integers and rational numbers;
• convert within metric and other customary measuring systems;
• apply properties to find missing angle measures in triangles;
• find area of circles, rectangles, triangles, and trapezoids;
• find perimeter of polygons and circumference of circles;
• find volume and surface areas of rectangular and other geometric solids;
• locate ordered pairs on a coordinate plane;
• graph inequalities and linear equations on a coordinate plane; and
• solve single-operation equations containing whole numbers, integers, and rational numbers.
Successful completion of this material prepares students for success in Algebra 1.
The main goal of Pre-calculus is for students to gain a deep understanding of the fundamental concepts and relationships of functions. Students will expand their knowledge of quadratic, exponential, and logarithmic functions to include power, polynomial, rational, piece-wise, and trigonometric functions. Students will investigate and explore mathematical ideas, develop multiple strategies for analyzing complex situations, make connections between representations, and provide support in solving problems. Students will analyze various representations of functions, sequences, and series. Discrete topics include the Principles of Mathematical Induction and the Binomial Theorem. Students will analyze bi-variate data and data distributions and apply mathematical skills to make meaningful connections with real-world situations.
Pre-calculus applies modeling, and problem-solving skills to the study of trigonometric and circular functions, identities and inverses, and the study of polar coordinates and complex numbers. Vectors in two and three dimensions are studied and applied. Problem simulations are explored in multiple representations—algebraic, graphic, and numeric. Quadratic relations are represented in polar, rectangular, and parametric forms. The concept of the limit is applied to rational functions and to discrete functions such as infinite sequences and series. The formal definition of limit is applied to proofs of the continuity of functions and provides a bridge to the calculus.
Instructional material includes a review of algebraic concepts and skills: the real and complex number systems, polynomials, algebraic fractions, exponents and radicals, linear and quadratic equations, inequalities, rectangular coordinate systems, lines and circles; Linear and quadratic equations and inequalities; graphs of equations, including lines, circles, parabolas; composition, inverses of functions; transformations of graphs; linear and quadratic models; equations and inequalities involving polynomials and rational functions; exponentials and logarithms with applications; trigonometric functions and inverse trigonometric functions: definitions, graphs, identities; real and complex zeros of polynomials; polar coordinates; DeMoivre's Theorem; conic sections; solutions of systems of equations by substitution and elimination; systems of inequalities; arithmetic sequences and geometric series.
A summary of specific tasks includes:
A. Compute with matrices and use matrices to solve problems.
B. Analyze the behavior of sequences and series.
C. Analyze and solve problems using polynomial functions.
D. Model and graph functions and transformations of functions.
E. Analyze the behavior of functions.
F. Solve problems using trigonometry.
G. Graph curves using polar and parametric equations.
H. Solve problems involving the geometric properties of conic sections.
I. Compute probabilities for discrete distributions and use sampling distributions to calculate approximate probabilities.
J. Analyze bi-variate data using linear regression methods.
Further emphasis is given to exponential form of complex numbers, geometric representation of complex numbers, roots of unity, applications of complex numbers to geometry, two-dimensional and three-dimensional vectors and matrices, determinants, dot and cross product, applications of vectors and matrices to geometry; probability, circular functions, and two- and three-dimensional vectors. The concepts of limit, derivatives, and power series are introduced. Trigonometry concepts such as Law of Sines and Cosines will be introduced. Students will then begin analytic geometry and calculus concepts such as limits, derivatives, and integrals.
The probability of an event is a measure of the chance that the event occurs; namely the relative possibility that an event will occur, as expressed by the ratio of the number of actual occurrences to the total number of possible occurrences. This instruction provides an elementary introduction to probability with applications.
I’ve learned about probability in various places including; on the job training (OJT) at Johns Hopkins Applied Physics Laboratory, Six Sigma training in Fortune Five aerospace, and collegiate Thermodynamics/ Solid State Physics instruction. Quantifying such a complex and illusive subject is no small success for the mathematics and, a point of great satisfaction for me.
Topics in this instruction include: the theory of probability and its applications; basic probability models (coin and dice tosses, cards, etc.); Venn diagrams, tree diagrams, odds, combinatorics (permutations, nPk and combinations, nCk); the axioms of probability, conditional probability and independence of events; sample spaces; random variables; the Strong and Weak Laws of Large Numbers, discrete and continuous random variables/vectors and probability distributions; Pascal's triangle, expected values, mean, standard deviation, Gaussian distributions, standardized test scores, statistical estimation and testing; Poisson and related distributions; joint, marginal, and conditional densities, moment generating function; binomial, univariate, and bivariate normal distributions; confidence intervals, correlation, and limit theorems; and introduction to linear regression.
Probability– Sample Spaces and the Algebra of Sets, The Probability Function, Combinatorial Probability, Axiomatic probability, a priori probability, Bayes' theorem, likelihood function, posterior probability distribution.
Random Variables– Hypergeometric probabilities, the variance, joint densities, combining random variables, further properties of the mean and variance, order statistics, random sampling and sampling distributions.
Special Distributions– The Geometric distribution, the Negative Binomial distribution and the Gamma distribution.
The Normal Distribution– Inferences about a population mean; Normal, t, ?2 and F distributions.
This course should also impart to the student the important idea that real phenomena can be modeled stochastically using random variables/vectors and their distributions. These modeling aspects, can be imparted through computer simulations, real experiments, and the use of historical data, and should make the course very useful to students in the physical, engineering, biological and social sciences. Calculus-level proofs of important results are presented or outlined.
The Preliminary SAT/National Merit Scholarship Qualifying Test (PSAT/NMSQT) is a program co-sponsored by the College Board and National Merit Scholarship Corporation (NMSC). It is a standardized test that provides firsthand practice for the SAT®. It also gives you a chance to enter NMSC scholarship programs and gain access to college and career planning tools. The PSAT/NMSQT measures: Critical reading skills, Math problem-solving skills and Writing skills. You have developed these skills over many years, both in and out of school. This test doesn't require you to recall specific facts from your classes.
Taking the PSAT was an excellent experience for me. Not only did it prepare me for what I would see on the SAT, but since I did quite well, it also built my confidence, prestige and recognition through National Merit Scholarship.
The PSAT/NMSQT includes five sections:
Two 25-minute critical reading sections = 48 questions
• 13 Sentence completions
• 35 Critical reading questions
Two 25-minute math sections = 38 questions
• 28 multiple-choice math questions
• 10 Student-produced responses or "grid-ins"
One 30-minute writing skills section = 39 questions
• 14 Identifying sentence errors
• 20 Improving sentences
• 5 Improving paragraph questions
The whole test requires two hours and 10 minutes.
It is always good to prepare for standardized tests to improve readiness, build confidence, and improve scoring. The PSAT/NMSQT includes the same types of critical reading, math, and writing skills multiple choice questions as the SAT®:
Sentence Completion questions measure your knowledge of the meanings of words and ability to understand how the different parts of a sentence logically fit together.
Passage-Based Reading questions measure your ability to read and think carefully about a single reading passage or a pair of related passages.
The math section of the PSAT/NMSQT requires a basic knowledge of number and operation; algebra and functions, geometry and measurement; and data analysis, statistics, and probability. You can use a calculator to answer math questions, but no question on the test requires a calculator. Please note that many calculator types are prohibited.
Multiple Choice questions ask you to decide which is the best of the five choices given.
"Grid-ins", or student-produced response questions, require you to solve a problem and enter your answer.
The multiple-choice questions on writing skills measure your ability to express ideas effectively in standard-written English, to recognize faults in usage and structure, and to use language with sensitivity to meaning.
Identifying Sentence Errors questions test your knowledge of grammar, usage, word choice, and idiom. You are required to find errors in sentences or indicate that there is no error.
Improving Sentences questions ask you to choose the best, most effective form of an underlined portion of a given sentence.
Improving Paragraphs questions require you to make choices about improving the logic, coherence, or organization in a flawed passage.
The most common reasons for taking the PSAT/NMSQT are to:
• Receive feedback on your strengths and weaknesses on skills necessary for college study. You can then focus your preparation on those areas that could most benefit from additional study or practice.
• See how your performance on an admissions test might compare with that of others applying to college.

What is the SAT and why is it important? The SAT comes from the Educational Testing Service (ETS), which is contracted by The College Board to create the test. The SAT is a significant factor in the college admissions decision.
Mathematics is one of the original sections of the SAT and has long given students trouble. Representing a third of your total SAT score, it is important that you do well. The SAT Math category covers varying math skills, ranging from simple arithmetic to geometry. Many students find this SAT category to be a problem, but strategies will allow you to overcome your fear. The Math skills required for the SAT are of a basic standard that should be within the reach of a tenth grade student. You don't need to learn lots of new formulas, but you will need to sharpen your thinking skills.
Questions are of two main types:
•Problem solving - multiple choice (5 answer choices)
•Student-produced response questions ('grid-ins')
The three Math sections are organized as follows:
•One section of 25 minutes containing 8 problem solving questions and 10 grid-ins
•One section of 25 minutes containing 20 problem solving questions
•One section of 20 minutes containing 16 problem solving questions
There are a total of 54 scored math questions on one test.
Math questions on the SAT will be of different difficulty levels. Each section will start out easy, move to medium level and end with hard questions. In any of the question types you may be tested on basic arithmetic, algebra, geometry and a few miscellaneous topics (mainly data interpretation and applied math). Remember that math skills improve with practice, so it is important to try full-length practice tests under timed conditions.
Strategies to maximize your score on the SAT:
• Get as many questions correct as possible with as few errors as possible. This strategy may seem obvious, but because the SAT scoring deducts an extra ¼ point for each incorrect multiple-choice answer, it is very important to remember. You will generally achieve “maximum right, minimum wrong” by doing all the questions that are easy for you, attempting the harder questions that you think you know how to do, and skipping the rest.
• The harder questions may require several steps to solve and will often have incorrect answer choices (also known as “traps”) that come from making simple mistakes. Most test takers should try to get the points they need (see the score table above) from the easier questions, which are worth the same as the harder questions but tend to take much less time to solve. For example;
• No wild guessing!
• Grid-ins: if you have a hunch, then go ahead and guess! There is no penalty for guessing in the grid-in section
• You shouldn't have to read the instructions at the beginning of each section. Know these ahead of time. You should also know, from memory, the math formulas given at the beginning of each section.
• Limit the amount of time spent on any one problem. Remember your ultimate goal: get as many questions correct as possible with as few errors as possible.

Main sections of this subject material include; Basic Algebra, Basic Geometry, Coordinate Geometry, Functions and Trigonometry, including integers, fractions, decimals, expressions and equations, word problems, inequalities, absolute value, functions & graphing, exponents and polynomials, rational expressions, probability and statistics, and many more topics, and their subtopics.
Statistics has to do with the collecting and analyzing of numerical data in large quantities. Topics include sampling and experimental design, sampling errors, descriptive statistics, basic probability (random variables, expected values, normal and binomial distributions); binomial and normal distributions, estimation, hypothesis testing (including Type I and Type II errors) and confidence intervals for means, proportions, and regression parameters; descriptive methods in correlation, and simple linear regression; analysis of variance, Student's t-test, percentiles, and z-scores.
Important principles include;
1. Exploratory analysis of data making use of graphical and numerical techniques to study patterns and departures from patterns.
2. The realization that data must be collected according to a well developed plan if valid information on a conjecture is to be obtained.
3. The realization that probability is a valuable tool for anticipating what the distribution of data should look like under a given model.
4. The fact that models and data interact in statistical work. Models are used to draw conclusions from data. Inference from data is a process of selecting a reasonable model, including a statement in probability language, of how confident one can be about the selection.
Trigonometry is the branch of mathematics that studies the properties of the sides and angles of plane or spherical triangles, the trigonometric functions, the calculations based on them and their applications. This course focuses entirely on plane trigonometry.
Specifically addressed are;
Measures of angles, Coordinate in a Plane, Applications of Special angles, The four solutions (cases) of an oblique triangle, the Laws of Sines, Laws of Cosines, graphical representations of the trigonometric functions, graphs of sin x and cos x, graphs of tan x, cot x, sec x, csc x; Fundamental Identities, Proving Trigonometric Identities, Inverse Trigonometric Functions, Trigonometric Ratios in Right Triangles, Trigonometric Functions on the Unit Circle, Linear and Angular Velocity, Translations of Sine and Cosine Functions, Modeling Real World Data with Sinusoidal Functions, Trigonometric Inverses and Their Graphs, Sum and Difference Identities, Double-Angle and Half-Angle Identities, Solving Trigonometric Equations, Normal Form of a Linear Equation
Trigonometric functions have applications in the physical and life sciences. The six trigonometric functions which are defined in terms of ratios are used routinely in calculations made by surveyors and navigators. Procedures using trigonometric tables and those using a calculator are included as needed to solve problems. Triangle solution problems, trigonometric identities, and trigonometric equations require knowledge of elementary algebra.
