Hello, students and parents! With my BA in Economics with Honors from the College of William and Mary, having successfully completed record-breaking triple course loads, and thus having quickly earned about 11 years of college credit, I tutor all levels of economics, mathematics, test prep, college planning, French, and politics, and more:

* Economics: Including Macroeconomics, microeconomics, and econometrics
- 100 to 400-level classes (MBA and college prep)
- Business economics and forecasting
* Mathematics: Through Calculus 3, Differential Equations (PDEs and SDEs), and Advanced Statistics
* Test Prep: GRE/GMAT/SAT/ACT, Study Skills and College Advising
* French, Politics, International Relations, and much, much more

My advanced academic studies, personal enthusiasm, and teaching experience combine to assist you in helping you to find economics and math not just easy but fun. A couple years ago, I was in your shoes. Economics and math seemed hard; yet once you understand, it becomes really easy. Today, I still remember how to take those ideas and communicate them the way I had wished they had been communicated. No matter how basic or advanced your objectives, I am entirely focused on helping you achieve your goals.

My economics background includes economic research at the Federal Reserve Board of Governors, completing advanced 400-level coursework across macroeconomics and microeconomics and such graduate-level coursework as Time-Series Econometrics and Cross-Section Econometrics. In addition to tutoring macro and micro, I have tutored many MBA and MFin students in many economics classes and TA-ed Applied Financial Derivatives--the hardest rated economics class at the College of William and Mary--and Econometrics. Helping teach these classes, I graded assignments and exams and helped students like you successfully complete their homework, develop original research projects, and discover how fun and useful economics truly is. In addition to having read hundreds of original research articles, I have completed dozens of economics projects using advanced concepts from micro and macro theory and econometrics, culminating in my honors thesis. Further, I have attended PhD-level conferences in which leading academics, including Nobel prize winners and eminent textbook authors (e.g. Wooldridge and Hamilton), and have presented original research. Because of my own academic studies, tutoring experience, and awareness of advanced technical aspects, I understand how difficult economics can be at the beginning, know how useful economics is, and how to make it a delight.

My mathematics background includes coursework through Calculus 3, Differential Equations, and graduate-level Statistics. Through grade school, my math performance included multiple first place math prizes in city-wide math competitions (e.g. MathCounts, Math Olympiad) and more recently includes work in stochastic partial differential equations, programming numerical solutions to mathematical problems, and original research involving panel data statistical analysis. A strong foundation in mathematics is tremendously useful and makes many other fields much easier, and I would be delighted to help you achieve your goals.

My statistics background includes undergraduate and very advanced graduate-level topics. My undergraduate experience includes Statistics, Econometrics, Political Research Methods, Experimental Psychology, and Nursing Statistics tutoring. My graduate-level background includes Time-Series and Cross Section Econometrics, artificial neural networks, Bayesian statistics (e.g. shrinkage, conditional probabilities, entropy pooling), global optimization (e.g. genetic algorithms, simulated annealing), multivariate statistics geometry (e.g. copulas, Mahalanobis, various advanced distributions), and Quantum Mechanics and Quantum Computing (including complex superpositioned probability).

Online tutoring is also really fun, which I discovered originally at a student's request. With Skype, email, and other online tutoring tools, I have taught students economic concepts, mathematics problems and derivations, and Time-Series Forecasting in STATA and Excel. Even if you don't have a webcam, I can still teach you what to learn to get the grade or complete your work project whether you are across Chicagoland or traveling for work worldwide.

My experiences have also included serving in the British Parliament, studying at Oxford University, the London School of Economics, and the top linguistics school in France, and helping businesses and financial institutions make sense of their data. Through these experiences, I have discovered that one of the things I love most is learning and helping students understand new concepts and succeed in-person and online.

Accounting

I have earned an A in Financial Accounting (including with an online component via McGraw-Hill's Connect). Using these concepts, I have completed additional private training on Discounted Cash Flow and Comparatives Analysis with Training the Street. Further, I have worked in accounting for a year at a major international French corporation and proposing and have lead financial data-driven projects to drastically increase company profits at a market leader. This background means I can explain key US accounting principles (GAAP, double-entry, accrual), their relation to financial statements (balance sheet, income statement, cash flow statements, and retained earnings statement), their vital importance to real businesses, and their relation to common investment bank valuation methodologies. While accounting can seem like a different language when you begin, I can help you achieve fluency (even in French). My objective is to do what it takes to help you reach your goals.

Algebra 1

I have won many awards in Algebra including for first place individual speed and team awards (MathCounts) and very high awards for Math Olympiad (scoring 24/25). Since then, I have continued to stay sharp in algebra by completing coursework in Differential Equations and advanced Calculus, by tutoring students in algebra and in quantitative GRE, and of course by applying algebra to everyday life.

Algebra 2

I have won many awards in Algebra including for first place individual speed and team awards (MathCounts) and very high awards for Math Olympiad (scoring 24/25). Since then, I have continued to stay sharp in algebra by completing coursework in Differential Equations and advanced Calculus, by tutoring students in algebra and in quantitative GRE, and of course by applying algebra to everyday life.

Biostatistics

Having completed six statistics classes, including graduate-level Time-Series Analysis and Cross-Section Econometrics, I have tutored dozens of students on statistical concepts and helped them craft their own original statistical research projects. These students have included Nursing Statistics students and others. I have conducted original statistical research in Experimental Psychology, Government Research Methods, and Economics/Finance, including my honors thesis forecasting economic crises using international panel data. (Exceptionally complex panel data combines observations from different places and times.) As a TA and tutor of two Econometrics classes at the College of William and Mary and as a WyzAnt tutor, I have helped dozens of students design their own research and analyze their results in STATA. For personal interest, I have advanced my statistical skills by attending academic conferences hosted by the American Statistics Association, the Econometric Society, the Society for Financial Econometrics, and STATA and might even have met and discussed statistics with the author of your textbook. Through this, I have gained familiarity with many statistical software packages (e.g. SPSS, STATA, EViews, and MATLAB) and various statistical programming languages. While I can mention my statistical qualifications, students totally make my day when they write:

Business

I have a certificate in Supervisory and Administrative Management, having completed coursework in Business Economics (Industrial-Organizational Economics), Human Relations in Applied Management, Human Resource Management, Independent Study in Management, and Principles of Management. I have completed additional extensive coursework related to business, including Financial Accounting, additional legal and finance classes, Intermediate Microeconomics, and forecasting econometrics. I have learned discounted cash flow and comparative analysis valuation methods through additional training by Training the Street. Finally, I have applied business coursework across businesses, including advancing from the mailroom to the executive conference room of a multimillion dollar international corporation within three days and have tutored MBA students who have described my tutoring as "fantastic".

Calculus

I have done coursework and earned A's through Multivariate Calculus 3 and Differential Equations, plus additional work involving stochastic partial differential equations. I am familiar with real-world calculus and differential equation applications involving such numerical methods as binomial trees and finite difference meshes applied to financial, economic, and physical data, including force fields, densities, business unit optimization, options pricing, springs, mechanical vibrations/oscillations, population modeling with harvesting, and thermal or stock price diffusion. If you would like any help with calculus, I would be delighted to be of service.

Chemistry

Having completed two years of Honors Chemistry, I would be happy to help you review the basics.

College Counseling

Having studied at five very different universities in three different countries (i.e., Oxford, LSE, William and Mary, in France, and ECC), I can offer unique insight into the college planning process. What is the hidden weaknesses of applying to a community college with the intent to transfer? (it's not what you think.) What are the advantages and disadvantages of the British system? Or of attending college in France? What college's professors present the best original research at academic conferences? What can you do now to strengthen your application? When I originally applied to colleges, I had no clue what to look for. Now I know and can share the knowledge I have learned with you.

Differential Equations

I have done coursework and earned A's through Differential Equations and have also earned an A in and TA-ed Applied Financial Derivatives, which involves deriving and solving the Black-Scholes-Merton stochastic partial differential equation and other stochastic differential equations related to derivatives pricing. To stay current on the latest developments, I have attended partial differential equations research conferences at the University of Chicago. Making differential equations useful, I have applied differential equations modeling to applications involving such numerical methods as binomial trees and finite difference meshes applied to financial, economic, and physical data, including force fields, densities, GDP forecasting, options pricing, the bouncing movement of springs, mechanical vibrations/oscillations, population modeling with harvesting, chemical solutions, anesthetics, and thermal and stock price diffusion. Thus, I can help you gain the understanding of differential equations you need for professions ranging from engineering and physics to economics, chemistry, medicine, and high finance. Differential equations is also one of those difficult classes in which good grades impress when you apply for admission to the most selective universities and graduate institutions. If you would like any help with Differential Equations, I would be delighted to be of service.

Econometrics

Academically, I have completed graduate-level Time-Series Econometrics and Cross-Section Econometrics. I also have TA-ed Econometrics and used econometrics extensively in assignments and in original research (e.g. my honors thesis). Further, I have attended top-tier PhD-level conferences in which leading academics, some with Nobel prizes and eminent textbook authors (e.g. Wooldridge and Hamilton), have presented original research on the forefront of econometrics. While I can mention my econometric qualifications, students totally make my day when they write:

"Great tutor, knows his material. Lewis is a tremendous tutor. He makes certain of your comprehension of the material. He sends a nice summary of the lesson after. Well worth it! Thanks Lewis." (Masters, Time-Series Forecasting)

If you would like any help with econometrics, I would be delighted to be of service.

Economics

My economics background includes completing advanced 400-level coursework across macroeconomics and microeconomics and such graduate-level coursework as Time-Series Econometrics and Cross-Section Econometrics. While earning my BA in Economics with Honors from the College of William and Mary, I tutored microeconomics and macroeconomics and worked for the Department of Economics TA-ing Econometrics and Applied Financial Derivatives, the hardest rated economics class at the College. Helping teach these classes, I graded assignments and exams and helped students like you successfully complete their homework, develop original research projects, and discover how fun and useful economics truly is. In addition to having read hundreds of original research articles, I have completed dozens of economics projects using advanced concepts from micro and macro theory and econometrics, culminating in my honors thesis. Further, I have attended PhD-level conferences in which leading academics, including Nobel prize winners and eminent textbook authors (e.g. Wooldridge and Hamilton), have presented original research. Because of my own academic studies, tutoring experience, and awareness of advanced technical aspects, I understand how difficult economics can be at the beginning, know how useful economics is, and how to make it a delight.

English

A native English speakers, I have studied English thoroughly including reading grammar guides (e.g. Fowler's, Strunk and White, and over a dozen quotations books) for fun, have professionally written a private verbal SAT practice tests, have always been a voracious reader, and even studied linguistics for a year at a top language school in France receiving a foreign language certification. In addition to my English skills, proficiency in a second language makes me all the more aware of the way language is constructed. Because of this background, my most well-published professor at Oxford wrote that I wrote better than almost any of his American students and awarded me Oxford's highest mark. This background has enabled me to earn in the top percents on standardized tests (e.g. GRE, GMAT, SAT, ACT), and I would be delighted to help you with English too.

ESL/ESOL

My academic studies, personal experience, and personal passion combine to assist you in helping you to speak English like a native. Academically, I have studied at the Center of Applied Linguistics in Besancon, France. The CLA is arguably the most prestigious language school in France. Over the course of a year, these intensive studies ranged across all aspects of second language acquisition, including grammar, syntax, and phonetics and have led native French speakers to exclaim, "I have lived in the United States for 8 years, and my English is nowhere near as good as your French!" However, my additional language studies include Spanish linguistics over the course of a year as part of a local Spanish-English bilingual class and accents and accent reduction. Via private tutoring, I have helped students for native Spanish, French, Chinese, and Arabic speaking backgrounds. But what truly sets me apart--aside from having learned a foreign language fluently as an adult--is my sensitivity and affinity for language--acquired over years of riveted study of the great grammar guides (e.g. Fowlers, MLA, Chicago, the Economist, Bierce, Stunk and White), growing up loving the most eminent dictionary in the English tongue (i.e. the Oxford English) and dozens of quotations books that exemplify these concepts in the best way to have ever graced the ear of anglophone-kind. And I understand personally the challenges of learning a new language and expressing it with perfection. For these reasons, I can understand and explain language better than other ESL practitioners. So contact me today, and perhaps you will be able to speak perfect English proverbially tomorrow.

Finance

I have earned As in International Finance, Financial Accounting (including with an online component via McGraw-Hill's Connect), and Applied Financial Derivatives, and have completed additional private training on Discounted Cash Flow and Comparatives Analysis with Training the Street. Professionally, I have worked as an Assistant Financial Manager at a major international French corporation and proposing and have lead financial data-driven projects to drastically increase company profits at a market leader. I have attended over 100 finance industry conferences and events, including those hosted by the American Finance Association, the Society for Financial Econometrics, Federal Reserve Bank banking conferences, and others that focus on a industry niches from quantitative finance and high-frequency trading to fundamental investing and analysis.

French

My academic studies, personal experience, and personal passion combine to assist you in helping you to speak French, la belle langue, like a native. Academically, I have studied at the most prestigious language school in France, the Center of Applied Linguistics in Besancon, France. Over the course of a year, these intensive French-language immersed studies ranged across all aspects of second language acquisition, including grammar, syntax, and phonetics, enabling me to teach French better than natives who lacks this knowledge, and culminated in my earning the Advanced DELF French Language Studies Diploma from the French Ministry of Education, resulting in skills that have led native French speakers to exclaim, "I have lived in the United States for 8 years, and my English is nowhere near as good as your French!" Via private tutoring, I have helped English-speaking students learn written and spoken French impeccably. Having learned a foreign language fluently as an adult, I still remember the challenges of learning a new language and trying to express it with perfection, which helps me better help and understand you. So if you think French has a certain je ne sais quoi and wish to learn to find le mot juste, then contact me today, and perhaps you will be able to speak French impeccably tomorrow.

Geometry

In addition to introductory geometry, I have studied Calculus 3 with Analytic Geometry, which discusses many of the concepts of Geometry except in multidimensional space instead of only a 2-dimensional plane. I have also tutored geometry as preparation for graduate school entrance examinations.

GMAT

I scored well within the top 10% on both the new GMAT and the new GRE on my first attempts. I have written practice standardized tests for a professional test-prep company. I have also learned the many GMAT/GRE tips and tricks. Being familiar with test takers' and test writers' perspective and with GMAT/GRE tips and tricks, I can help you understand GMAT tests, answer test questions correctly, and speed accurately through the test.

Government & Politics

Having earned a perfect 5 on my AP US Government test in high school, I have since studied many aspects of Government and Politics at Oxford, at the London School of Economics and Political Science, and within my International Relations major at the College of William and Mary. Professionally, I have worked on a US presidential campaign get out the vote operation in the most fiercely contested battle-ground state and have interned legislatively with five members of Parliament in the "Mother of Parliaments" at the British Palace of Westminster.

GRE

I scored well within the top 10% on both the new GRE and the new GMAT on my first attempts. I have written practice standardized tests for a professional test-prep company. I have also learned the many tips and tricks. Being familiar with test takers' and test writers' perspective and with GRE/GMAT tips and tricks, I can help you understand GRE/GMAT tests, answer test questions correctly, and speed accurately through the test.

Law

I have completed multiple paralegal classes (e.g. Introduction to Paralegal, Business Law) and Jurisprudence at Oxford.

Linear Algebra

In our data-driven age, applications of linear algebra are ubiquitous. Linear algebra applies math to such matrices as any Excel spreadsheet, and using the power of matrices, you can calculate millions of values or solve billions of equations simultaneously. I have used linear algebra in such advanced math classes as Multivariate Calculus 3, Differential Equations, and graduate-level Time-Series Analysis and Cross-Section Analysis. Multivariate Calculus 3 uses the basic operations of Linear Algebra, including dot products and cross products, to calculate speeds, positions, and forces in infinite-dimensional space. Differential Equations uses linear algebra to solve high-order systems of differential equations to calculate eigenvalues and eigenvectors using Cramer's rule. Building on Linear Algebra as a prerequisite, Time-Series Analysis begins its first week covering not matrix algebra but matrix calculus, using linear algebra to calculate a plethora of statistics, just as Cross-Section Analysis uses the linear algebra techniques of factor rotation in principal components analysis to reduce the dimensionality of correlated variables. In addition to using linear algebra in this more advanced coursework, I have also used the techniques of linear algebra professionally in calculating portfolio analysis and risk statistics in MatLab. If you would like help with Linear Algebra, I would be delighted to be of service.

Logic

I took logic and earned an A. Since then, I have continued to study additional fallacies and have applied it in advanced philosophy (e.g. Philosophy of Mind, of Law, and of Politics) while studying abroad at the University of Oxford.

Marketing

Professionally, I have experience leading quantitative web marketing (SEO, SEM) campaigns, have written copy, and have marketed businesses online. Well-rounded, I also have additional British political PR experience. In addition to a BA in Economics, I have completed 5 courses and a certificate focused in business and additional familiarity with quantitative statistical, time-series, and cross sectional methods to evaluate marketing campaigns. I have also tutored a NYU student in an MS in Integrated Marketing quantitative methods class including various statistical and ANOVA research designs.

Philosophy

In addition to majoring in Economics and International Relations, I have completed the equivalent of a major in philosophy, including Introductory Philosophy, Logic, Honors Ethics, Social and Political Philosophy, Contemporary Analytic Philosophy, Non-Western Humanities, and have completed a self-designed honors independent study in Theoretical Cosmology studying under a PhD in Philosophy of Science. At Oxford, I completed courses (or called there "read papers") in Jurisprudence (i.e. Philosophy of Law), Social Theory (i.e. Philosophy of Politics), and Philosophy of Mind (i.e. Philosophy of Psychology). With this background, I can help you avoid the informal fallacies, perfect the techniques of Aristotilian and Boolean logic, enhance your Millian and Benthamite utility and Kantian deontology, evaluate the logic of St. Anselm's arguments, make wise Pascalian wagers about the existence of God, find the virtuous Nichomachean mean between two vices, and understand like Nagel "What is it like to be a bat". The primary challenge to philosophy is ensuring that all your arguments are indisputably logical according to the mathematical laws of logic so that while meaningfully testable no professor can falsify your statements in the Popperian sense. Then, in an ideal world of forms, you have to express your ideas eloquently. As the tutor Aristotle did for Alexander the Great, I can help you achieve logical rigor and verbal eloquence assisting you on your path to becoming a Platonic philosopher-king.

Prealgebra

I have won many awards in Algebra including for first place individual speed and team awards (MathCounts) and very high awards for Math Olympiad (scoring 24/25). Since then, I have continued to stay sharp in algebra by completing coursework in Differential Equations and advanced Calculus, by tutoring students in algebra and in quantitative GRE, and of course by applying algebra to everyday life.

Precalculus

I have completed coursework and earned A's through Multivariate Calculus 3 and Differential Equations, plus additional work involving stochastic partial differential equations. I can help with all aspects of Pre-Calculus, including vector and matrix math, identifying real and complex roots (e.g. via graphs and positive real zeroes), rules of exponents and logarithms, graphing exponential and parabolic equations, identifying equations for exponential and parabolic graphs, trigonometric functions and the unit circle, arithmetic and geometric series, converting repeating decimals to fractions, probability (e.g. permutations, combinations, and conditional and independent probabilities), binomial theorem and binomial trees, and real-world applications for all of these (e.g. firing cannonballs, investment portfolios, options pricing, heat diffusion). While I can mention my mathematical qualifications, students totally make my day when they write:

"Wonderful Tutor!! We highly recommend Lewis!! My son was failing pre-calculus/trigonometry before Lewis came along and his confidence was the lowest I've ever seen. After only 3 sessions, his grades have improved tremendously. He received a "B" on a quiz last week, and an A+ this week! Lewis provides clear explanations to a complex subject-matter through real-life examples. His passion for math is contagious!"

Probability

Having completed six probability and statistics classes, including graduate-level Time-Series Analysis and Cross-Section Econometrics, I have tutored dozens of students on statistical concepts and helped them craft their own original statistical research projects in psychology, economics, and nursing. I have conducted original statistical research in Experimental Psychology, Government Research Methods, and Economics/Finance, including my honors thesis forecasting probabilities economic crises using international panel data. (Exceptionally complex panel data combines observations from different places and times.) Empirically, I have familiar with such graduate-level probability models as linear probability models and ordered and multinomial logits and probits and with Bayesian probability. As a TA and tutor of two Econometrics classes at the College of William and Mary, I helped dozens of students design their own research and analyze their results in STATA. For personal interest, I have advanced my statistical skills by attending academic conferences hosted by the American Statistics Association, the Econometric Society, the Society for Financial Econometrics, and STATA. Through this, I have gained familiarity with many statistical software packages (e.g. SPSS, STATA, EViews, and MATLAB) and various statistical programming languages. If you would like any help with probability, I would be delighted to be of service.

Psychology

I have an extensive background in psychology, including Honors Intro, Social Psychology, Experimental Psychology, Child Psychology, Adult Psychology, Marriage and Family, additional training with Dr. Ekman's Micro-Expressions Training Tool and Subtle Expressions Training Tool, and extensive personal reading. This familiarity includes the conceptual elements and the statistical concepts. Exceptionally, I can offer a unique interdisciplinary understanding having examined many psychological topics using the tools not only of controlled psychological experiments but also using social statistics and analytic microeconomic and political science models analyzing individual psychology.

Religion

I have completed coursework in Comparative Religions, have read religious texts, and/or have visited religious places of worship within the various denominations and sects of Christianity, Islam, Judaism, Hinduism, Buddhism, Zoroastrianism, Sikhism, Greek and Roman Mythology (and proto-Greek Indo-European beliefs), Egyptian Mythology, Native American beliefs, Jainism, and Shintoism. I have also studied religion within the context of World History classes, honors World Literature classes, Non-Western Humanities (including the significance of religious artwork), World Philosophy classes (e.g. St. Anselm, Augustine), Chinese and Japanese Politics (e.g. Shinto, Daoism, Confucianism, and US History (e.g. Jonathan Edwards, Great Awakenings, Puritanism, Transcendentalism, Mormonism, Deism). I am somewhat familiar with Christian apologetics (e.g. C.S. Lewis, Lee Strobel) and critical traditions (e.g. Bertrand Russell and Richard Dawkins). Of possible interest, I once saw Pope John Paul II during a Latin mass in St. Peter's Basilica in Vatican City, have toured the cathedrals of Europe and of England, attended the same Oxford college as William Tyndale (who wrote the precursor to the King James Bible), and have inquired about the beliefs of and have joined debates between devotees of different religious traditions found most vociferously at Speakers' Corner, Hyde Park, London. I have friends of many religious traditions who have informed my understanding of their beliefs. Religious beliefs are at the heart of the values and cultures of many of the world's 6.8 billion people, and without value or judgment I can help you make sense of many of the religious traditions of the world.

Social Studies

My BA in Economics and in International Relations provides a solid grounding throughout the social sciences, including extensive coursework in psychology, history, politics, and other social science fields. I have conducted and helped students conduct dozens of social science research projects through the graduate level, have prepared for college and AP tests in social sciences, and would be happy to help you too.

STATA

I have used STATA extensively in such graduate-level econometrics classes as Time-Series and Cross-Section as well as in basic Econometrics. I have used STATA for dozens of class assignments, for original research (i.e. my honors thesis), and in helping 60 students when I TA-ed Econometrics. Furthermore, I have attended a STATA conference and heard the president of STATA present on the latest capabilities of the STATA software and STATA users spanning disciplines ranging from cancer research and genetics to sociology and econometric theory present original research produced using STATA.

Statistics

Having completed six statistics classes, including graduate-level Time-Series Analysis and Cross-Section Econometrics, I have tutored dozens of students on statistical concepts and helped them craft their own original statistical research projects. I have conducted original statistical research in Experimental Psychology, Government Research Methods, and Economics/Finance, including my honors thesis forecasting economic crises using international panel data. (Exceptionally complex panel data combines observations from different places and times.) As a TA and tutor of two Econometrics classes at the College of William and Mary and as a WyzAnt tutor, I have helped dozens of students design their own research and analyze their results in STATA. For personal interest, I have advanced my statistical skills by attending academic conferences hosted by the American Statistics Association, the Econometric Society, the Society for Financial Econometrics, and STATA and might even have met and discussed statistics with the author of your textbook. Through this, I have gained familiarity with many statistical software packages (e.g. SPSS, STATA, EViews, and MATLAB) and various statistical programming languages. While I can mention my statistical qualifications, students totally make my day when they write:

"Great tutor, knows his material. Lewis is a tremendous tutor. He makes certain of your comprehension of the material. He sends a nice summary of the lesson after. Well worth it! Thanks Lewis." (MFin, Time-Series Forecasting)

If you would like any help with statistics, I would be delighted to be of service.

Study Skills

I have completed consecutive record-breaking triple course loads of 46 and 38 (also 28 and 24) semester hours with over a 3.7 GPA and have completed a semester of credit in a trimester of time at Oxford University performing in the top 15% of Oxford students (first honors level). I know how to study very well indeed and would be delighted to help you achieve your goals.

Trigonometry

I have completed coursework and earned A's through Multivariate Calculus 3 and Differential Equations, plus additional work involving stochastic partial differential equations. I can help with all aspects of Trigonometry/Pre-Calculus, including trigonometric functions and the unit circle, vector and matrix math, identifying real and complex roots (e.g. via graphs and positive real zeroes), rules of exponents and logarithms, graphing exponential and parabolic equations, identifying equations for exponential and parabolic graphs, arithmetic and geometric series, converting repeating decimals to fractions, probability (e.g. permutations, combinations, conditional and indepedent probabilities), binomial theorem and binomial trees, and real-world applications for all of these (e.g. firing cannonballs, investment portfolios, options pricing, heat diffusion). While I can mention my mathematical qualifications, students totally make my day when they write:
