William made an immediate connection with my daughter, Alex and got right down to business. His enthusiasm for pre-calculus is evident and contagious. After he left Alex said she finally felt good about the course and didn't approach the homework with trepidation as she has in the past. Just this one lesson has given her a great confidence boost. Thank you, Willliam!

I sent him my Pre-Cal review ahead of time before he came. When he showed up at my house he was rather prepared. He even bring his own textbook, calculator, and paper just in case I didn't have one of those things. Not to mention he actually he showed up when I had to schedule a tutor a last minute. Which is pretty great. He was super sweet and really helpful. I asked a lot of really dumb question; he was very patient with me. I recommend him.

William has been working with my son for 2 years now and as helped him not only improving his grades in math but gaining confidence that he can improve.

Thank you for all your support this year.

My son has only had one session with William so far, but we are very glad to have the opportunity to work with William. He clearly has enthusiasm that is matched by his knowledge and experience. We are very optimistic that coming sessions will be very productive!

Our son is being tutored by Mr William in Math, Geometry, Pre-Calc and SAT Prep, and we have found him to be an excellent tutor for our son.

He was very helpful in helping me hone my skills for the SAT. He was very patient, informative, and encouraging, especially when explaining concepts I was lacking in. Overall, he was much more helpful than the big-name prep course I took. Thank you Mr. G. for your help!

Mark has been wonderful tutoring my daughter! She has worked with him for 5 months in physics and pre cal/trig. She has more confidence now and went from a C in both subjects to a B in both. We really appreciate his patience and kindness. My daughter is looking forward for him to help her over the summer and for her senior year! Thank you Mark!!!

Mr. G was exactly what we were looking for, a true educator. Someone with the knowledge, experience and skills to deliver the mathematical concepts to my son, a GT student. We highly recommend him.

William is a treasure. He is knowledgeable in many subjects and was able to help my sophomore son with his school work. We look forward to meeting with him regularly and working on organization skills.

Mr. G is exceptionally competent in math, physics, English, computer topics, etc... He has been an invaluable source of multi-faceted knowledge.

The tutoring session was very helpful. I will certainly use him in the future. He helped me a lot. I needed help with algebra, and he broke it down where I could understand it. Thank you, William.

William was great with our son. He helped him so much the very first lesson. They have a plan mapped out as to how to help him the best, and I can see my son's confidence already changing!

My son and I met with William on Saturday, Oct 4th. He will be helping him with both PAP Algebra II & PAP Physics. My son enjoyed and was engaged for the entire 2-hour session. He told me that he did not even think about the time until I came in prior to the session wrapping up. That's a great sign. William seems to be an excellent teacher for an 11th grader to say that! He was patient, knowledgeable and most of all, he cares about my son's success in school. We are looking forward to future sessions and my son's grades improving as a result.

My son is eager to learn and feels very comfortable with Mr. G. He has improved his math skills with Mr. G and we plan on continuing these sessions as long as needed.

Mark has been amazing with my son. He started with tutoring him in 8th grade and continued through high school Geometry last year and now Algebra 2. My son's grades went from low 70s or even 60s to in the 90s by the end of the school year. Not just that but, Mark gave him so many tips on how to overcome test anxiety. My son has become so confident in the last couple years, and his motivation has grown by leaps and bounds.

Mark has been great helping my daughter prepare for the SAT. He has helped her build her confidence in math and reviewed the subjects she did not remember anymore. I am sure her SAT score will be improved due to the work Mark has helped her with.

My need of MCAT prep work is met very well with experience and planning by Mr. G! I would recommend him to anyone!

In just the first few sessions, this tutor was able to give my teen perspective on the individual pieces of information she was learning, which significantly increased her understanding of the material. It's one thing for a student to be able to recite math theories, but it's significantly better for that student to know how, when and why to apply those theories to actual problems. The impact was immediate -- my teen was able to complete the entire section of problems she worked on alone after the review session, because she had been given the tools to analyze the problems. We could not be more pleased with the quality of the services provided by this tutor, nor with his accessibility and dedication to making sure that the student has a thorough understanding of the material as a foundation for future learning.

Approved subjects are in **bold**.

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.

I have tutored and/or taught Algebra I for over 40 years. While majoring in math in college, I often helped fellow students who were struggling with math. The math courses I took in college included Calculus, Advanced Calculus, Linear Algebra, and Abstract Algebra. During my years as a graduate student at Duke University, I tutored undergraduates and students in the MBA program.

I am certified in Secondary Math in the State of Texas and have taught Algebra I in the Irving ISD. Topics usually covered in Algebra I include number systems, properties of real numbers, order of operations (PEMDAS), prime numbers and factoring, exponents, simplifying expressions, solving equations and inequalities of one variable, properties of linear equations and inequalities, solving systems of linear equations and inequalities, introduction to quadratic equations and inequalities.

I have tutored and/or taught Algebra II for over 40 years. While majoring in math in college, I often helped fellow students who were struggling with math. The math courses I took in college included Advanced Calculus, Linear Algebra, Complex Analysis and Abstract Algebra. During my years as a graduate student at Duke University, I tutored undergraduates and students in the MBA program.

I am certified in Secondary Math in the State of Texas and have taught Algebra II in the Irving ISD.

I have enjoyed chemistry since I was in elementary school and received a chemistry set for my birthday. When I was finally able to take chemistry in high school, I took to it like a duck to water. I excelled in A. P. Chemistry and placed out of first semester chemistry in college. Although my interests in math eventually won out over chemistry when I had to declare a major, I have never lost my interest in chemistry. I now study biochemistry and nutrition as one of my hobbies.

In general, the topics covered in chemistry include, but are not limited to, the following: the history of chemistry, measurement and the metric system, the mole concept, chemical reactions and stoichiometry, energy and chemical reactions, states and properties of matter, the periodic table, chemical bonding, atomic and molecular structure, gas laws, concentrations of solutions, phase diagrams, intermolecular interactions, reaction kinetics, chemical equilibrium, modern acid-base theory, buffers, chemical thermodynamics, electrochemistry and nuclear chemistry. Topics may further include transition-metal chemistry, an introduction to organic chemistry and qualitative inorganic analysis.

I have played chess for over 50 years. While in high school my best friend and I played frequently. At that time, he was one of the top 25 players in the U. S. A. under age 16. Needless to say, I learned much about the game during the many, many times he beat me. However, as time past and my skills improved, I began to win more and more games against him.

Although I was not able to play on a regular basis while raising a family, I play regularly now both online and in face-to-face matches.

I am familiar with all of the rules of the game and the various strategies which one can employ. I know all of the standard openings and am familiar with most of the standard reference works including Modern Chess Openings.

Discrete mathematics is concerned with the relationships among mathematical structures that are discrete instead of continuous. For example, the arithmetic of integers would be a topic in discrete mathematics, whereas the arithmetic of all real numbers is in the realm of continuous mathematics. Broadly speaking, the topics in discrete mathematics include, but are not limited to, the following: logic, proofs, set theory, number theory, linear algebra, graph theory, probability, permutations and combinations, algorithms, and computability theory. I have experience in these areas through my undergraduate and graduate course work and my study of number theory and computability.

Geometry was one of my favorite subjects in Junior High School. I had an awesome teacher who recognized my abilities and encouraged my explorations into the subject matter.

I am certified in Secondary Math in the State of Texas and have taught Geometry in the Irving ISD. Topics usually covered in Geometry include points, lines, angles, properties of angle formed by parallel lines with intersecting lines, triangles, the Pythagorean theorem, quadrilaterals, polygons, solving equations and inequalities involving geometric figures, properties of irrational numbers.

I began studying linear algebra during high school as part of my algebra II and pre-calculus classes. During college I continued my study with courses in linear algebra and abstract algebra. In those courses I worked with the properties of fields, vector spaces and linear subspaces. This included work with determinants, matrices, scalar operations, linear transformations, solutions of multi-variable systems of linear equations and functional analysis.

I have taught Pre-Calculus as recently as the 2013-2014 school year. Since then I assisted several students with this subject and have several students with whom I will be working in the current school year. While majoring in math in college, I often helped fellow students who were struggling with math. The math courses I took in college included Advanced Calculus, Linear Algebra, Complex Analysis, Abstract Algebra and Statistics.

During my years as a graduate student at Duke University, I tutored undergraduates and students in the MBA program in a variety of math courses including precalculus and the Calculus.

I am certified and highly-qualified in Secondary Math in the State of Texas. Pre-Calculus is about the analysis of functions and their behavior. Topics usually covered include various properties of functions: domain and range, graphs, end behavior, piecewise and composite functions, factoring and finding the roots of higher order polynomials, exponential and logarithmic functions, rational expressions, conic sections, parametric functions, trigonometric functions, trigonometric identities, polar coordinates, powers and roots of complex numbers and vectors.

I have over 40 years of experience with public speaking. I took courses in the subject in high school, college and graduate school. For 22 years I served as a pastor in various churches from different denominations, which required that I prepare at least one sermon on a weekly basis. In addition to sermons, I have spoken at a variety of events, at times with little advance notice.

Since the STAAR tests are basically end-of-course exams in various subjects, I am able to assist students with the preparation for these tests since I have taught and/or tutored the subjects on which these tests are based. In addition, I have extensive experience in helping students prepare for a variety of standardized tests, including the TAKS tests (which were the predecessor to the STAAR tests).

Having struggled with ADD in my own life as a student, I understand the difficulties many have in developing good study skills. Since my wife and I educated our children at home, we were able to spend considerable time helping our children develop good study skills. When I began teaching math in the Irving ISD I worked with my students to help them with their overall academic progress which included helping them to improve their study skills. In fact I am currently working with one of the students I tutor to help him become more organized in his study habits. Developing good study skills involves learning good time management; using a calendar to schedule appropriate time to study and complete lessons, such as term papers; learning which subjects require daily practice and completion of homework versus those which can be addressed in blocks of time; developing techniques to overcome learning challenges such as ADD/ADHD, dyslexia, etc.; and learning the importance of developing overall discipline in one's life.

I have been tutoring students since I was a student at Davidson College. This continued through my years as a graduate student at Duke University where I was part of the team that helped tutor student athletes. I am certified in Secondary Math in the state of Texas and have taught Algebra I, Geometry, Algebra II and Math Models in the Irving ISD. In that capacity I worked with students who had a wide range of abilities in math, both the math-challenged and the proficient. In addition, I worked extensively with students to improve their testing strategies to help with the TAKS test and the SAT. As a Secondary Math Teacher, an essential part of my job was preparing my students for the TAKS exam. We spent a significant amount of time each week with drills and testing strategies in order to help prepare them for the test. We also conducted practice testing sessions through the year to identify areas in which each student needed additional instruction. I am qualified to tutor for both the ACT and the SAT. Besides math, I have a strong background in reading, science and social studies, and I also tutored students in these subjects and helped prepare them for the TAKS exams in these areas.
