Math, Statistics, SAT~ACT~SSAT Tutor -- very patient and effective

Hello! I have been a professional tutor since 2003, specializing in math (pre-algebra through AP calculus), AP statistics, and standardized test preparation. I am very effective in helping students to not just get a better grade, but to really understand the subject matter and the reasons why things work the way they do. I do this in a way that is positive, supportive, and also fun. I explain difficult math and science concepts in simple English, and continue working with students until they ... [more]

Algebra 1

Algebra 1 methods and concepts are the foundation for all of the future studies of mathematics. However, in addition to knowing these, the results of doing algebra work must also be correct. That is why I teach my students to do the work in a disciplined and organized way: write all the steps down, check the results at each step, and organize their written work in a very clear way. These skills minimize the chance of making careless errors. I also begin to introduce students to the functionality of the graphing calculator; it's the skill that would serve them well both now, and in the future. In addition, I work with my students on test taking and study skills. There are a large number of skills learned in Algebra 1. Many students, that I tutor in upper level math, have poor command of these, so I invariably end up teaching them Algebra 1 material from the beginning.

Algebra 2

Working with functions is a big part of Algebra 2. This includes the inverse of a function, function composition, Polynomial, Rational, Radical, Exponential, Logarithmic, and Trigonometric functions. Other concepts learned in Algebra 2 are conic sections: Parabolas, Ellipses, and Hyperbolas, sequences and series, and many others. I teach my students graphing these functions, including transformations, and how to understand the behavior of the function by analyzing its equation and graph. I also teach them how to use the graphing calculator - a very helpful and necessary skill, when working with many of the concepts of this course. To be able to do well with this material, you need to be comfortable with the skills learned in Algebra 1. I can help you review these skills, or even learn them from scratch.


If you are currently taking your first course in calculus, then you have already discovered that the concepts studied here are very new and different. They are also very confusing. I can help you with some of the new concepts that are introduced in Calculus. They are: Limits, Rules of Differentiation, Related Rates, Optimization problems, Riemann sum, Techniques of Integration, Differential Equations, Parametric Equations, Polar Coordinates, and Partial Derivatives. Calculus work requires extensive use of the many different methods learned in Algebra 1. I can review these methods with you, or teach them to you from scratch. And the way I do this will make it easy for you to understand and remember.




Study of Precalculus serves as a preparation for Calculus and other higher level math subjects. It deepens student's understanding of the concepts learned previously in Algebra 2 and Geometry, as well as introducing new concepts and ideas, like Polar coordinates, Vectors, and Parametric equations. When I work with students in Precalculus, I teach them extensively the concepts of Trigonometry, various families of Functions, Analytic Geometry (Parabolas, Ellipses, etc.), and Sequences/Series. In addition, I teach them how to use the graphing calculator more effectively. Graphing calculator is a very useful tool in understanding difficult concepts, applying these concepts to problems, and checking the results of one's work.


I have tutored many students in Trigonometry, very often as part of a course in Precalculus, or as a stand alone course. In addition to the SohCahToa definition of trig functions (using the right triangle), I teach students the Unit Circle approach: the definitions of the six trigonometric functions, the radian measure of angles, and finding exact values of these functions for special angles. Once these skills are mastered, I teach students how to graph the Sinusoidal functions and the rest of the trigonometric functions, including the inverse (arc) functions. I also help my students become confident in proving (establishing) trigonometric identities, use Double-, Half-angle, and other formulas, and teach them how to solve trigonometric equations. Throughout, I teach my students the effective use of a calculator, and show them effective ways to memorize the many facts and formulas, that are used in trigonometry.


I tutor AP Statistics and college level introductory statistics courses for various disciplines: behavioral sciences, economics, health sciences, business, etc. Many students, who are new to statistics, think of it as ?pure math? subject. However, a big part in learning statistics is to apply statistical reasoning to the real world situations. I teach my students both the mathematical concepts of statistics and probability, and how to apply these concepts to word problems: recognize the statistical setting described in the scenario, then apply the correct method to solve the problem. The many positive reviews left by my students attest to my effectiveness in helping them with statistics.

SAT Math

I prepare students for the following SAT tests: Math portion of the ?big? SAT and the SAT Subject Math Test, Levels 1 and 2. I began prepping students for these tests as an instructor for a couple of premier Test Prep companies. In the 10+ years since then, I have honed my skills and knowledge by prepping hundreds of students one-on-one. In addition to teaching you the timing strategies, the multiple choice based strategies, ways of using the calculator effectively, and working efficiently on each problem, I can work with you on the topics that require remediation. With this approach to standardized test preparation, I can help you improve your test score whether you are quite new to the test, already had a lot of prep, or somewhere in between.


ACT Math

I have been preparing students for the Mathematics and Science Tests of the ACT exam since 2003. I am very experienced and knowledgeable about these tests, having helped many students get their highest scores on them. I will teach you specific strategies that are very useful for the Mathematics Test. These include proper pacing, strategies for utilizing the answer choices, and the most efficient approach to answering each question, among others. I will help you review the underlying math concepts, and teach you effective ways of using the calculator. For practice I use the actual ACT exams, that were administered to students in the past. This is in addition to the homework problems, that I assign as practice of the reviewed math material.

ACT Science

I have been preparing students for the Mathematics and Science Tests of the ACT exam since 2003. I am very experienced and knowledgeable about these tests, having helped many students get their highest scores on them. I will teach you specific strategies that are very useful for the Science Test. These include proper pacing, how to read the information in graphs, diagrams, and tables, identifying the trends in the data, and specific strategies for each of the three types of passages found on the Science Test. There are other strategies that are applicable to you individually - I will help you to identify and use them effectively. For practice I use the actual ACT exams, that were administered to students in the past.
