Andrei tutored my daughter for SAT Math, and for the SAT Math 2 subject test. His online classes were amazing and she grasped the subject matter quickly. Andrei also gave her great tips on working faster and more efficiently. This helped tremendously on the exams. Andrei tutored her for three months for the SAT Math, she took the exam once and scored a 780 on the math. He then tutored her for a month for the SAT 2 math, she scored an 800 on that exam. We are very grateful to Andrei, for helping her achieve this. I would recommend Andrei very highly, his patience and dedication is outstanding! Thanks Andrei!

Andrei is clearly a brilliant mathematician. He is very much interested in taking his students to a new frontier with their math. Unfortunately for us his intense teaching style was not a good fit for our daughter...but if you have a student who responds well to this manner of teaching I believe they will benefit tremendously.

Andrei is a most thoughtful, responsive and skilled tutor. As a mathematician, he is, in my eyes, unparalleled. Andrei truly cares about giving my son the reasons for WHY certain theories and concepts exist, and he therefore puts them in context, never to be forgotten. It is a true honor to work with a brilliant teacher like Andrei! I whole-heartedly recommend Andrei to anyone who yearns to discover a passion for mathematics, especially, and sadly, since this process rarely happens at school!

Andrei is exceptional and has a unique approach to teaching fundamental understanding of math concepts. Once a student clearly and soundly understands MATH fundamentals, the student can grow. We are honored to have a chance to work with someone who has these exceptional skills. For our planets future engineers and scientist, Andrei's tutoring will be priceless.

Andrei tutored my two daughters ages 10 and 12 for two years. I feel truly blessed to have found him through Wyzant. Not only is he an extremely well-educated mathematician, but he also clearly loves to teach children. It was not clear during the tutoring sessions who was having more fun, Andrei, or my daughters. His vast knowledge was put to good use in explaining, elaborating, and extrapolating in a way I could never hope to emulate. He was able to teach the girls new concepts, but his real value was in teaching them to think about the broader ramifications of new discoveries, so that instead of just collecting an assortment of facts and rules, they were able to gain a deeper understanding overall. If we hadn't moved across the country, we would still be using him, and I would recommend him in a heartbeat to anyone, especially someone with talented math kids.

Andrei brings a unique perspective to the process of learning mathematics. He is adept at encouraging the ability to conceive and calculate solutions to problems mentally, ultimately aiming to eliminate the need for figuring things out on paper or with the use of a calculator.

The student must invest in himself/herself by agreeing to practice between sessions; by looking back at the processes of mathematical applications Andrei has introduced during the face-to-face inspection, discussion of the SAT math modules.

Andrei is quite exceptional. His passion for teaching math is more than just getting the right answers. It's changing the way his students think of math in the traditional sense and allowing them to embrace concepts in the simplest of ways so that the language of math becomes fluent within them. The numbers flow and fall into place and the correct answer is all that is left on the paper.

Great tutor!! Andrei was preparing our child for Math part of SAT and ACT. He is very knowledgeable and explains difficult concepts clearly, very patient. We were very impressed with the results. Our child score was in a top 2% on SAT and top 3% on ACT. I do not think you can find a better tutor. I would definitely recommend Andrei!!

Very happy with Andrei as my daughter's math tutor, he is very patient, explains very clearly difficult concepts, very encouraging and very helpful.

I have just finished a tutoring from Andrei and I must say I am completely impressed both with his teaching style and his depth of knowledge. I think that you would not be able to find a better tutor.

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.

Before completing my Ph.D. in Discrete Mathematics at Yale University, my specialization and master's thesis at Kiev University (U.S.S.R.) were in Algebra.

Back in my previous, academic life, I taught Multivariable Calculus at Yale University, and Calculus 1 and Calculus 2 at University of Waterloo. Over the past few years, I tutored many high school and college students in calculus at all levels. My younger high school students have achieved the score of 5 on the AP Calculus BC exam in 9th or 10th grade.

My PhD Adviser at Yale University had a joint appointment at the Mathematics and the Computer Science departments. Consequently, I spent a significant amount of time studying algorithms, computational complexity, and other areas of interest to Computer Science. I am also fluent in several programming languages, such as Perl, PhP, and Java. Finally, one of my first students at WyzAnt was working towards his Master's Degree in Computer Science, needing help with his Algorithms class.

While working towards my Bachelor and Master degrees in Mathematics, I took---and aced---an in-depth three-semester course in Differential Equations (including both Ordinary and Partial DEs). Later on in my academic career, I taught some of it at the college level in my calculus class.

My PhD theses---as well as postgraduate research---were in the area of Discrete Mathematics.

Did you know that our Founding Fathers were almost universally educated in geometry? In their private letters to friends, they would make references to Euclid's the Elements the same way we would talk today about Google, or iPhone, or Twitter. (Except being able to talk about these modern realities is not a sign of a solid education :)

Until a few hundred years ago algebra gave modern mathematics ability to record information concisely---in formulas---geometry had done so---pictorially---for over two millennia.

A sidebar: When I taught at University of Waterloo, I organized a minicourse in Projective and Conformal Geometries.

I have been successfully preparing for ISEE those of my students who are applying to highly selective private schools. Last December, one of my students (a 5-th grader) placed in 98-th percentile in ISEE Math.

Per my PhD program requirements, I taught a course in Linear Algebra at Yale University.

Starting in the Summer of 2013 twice a week, and continuing during the school year weekly, I have been running a physics class for exceptionally gifted students. Progressing slowly, we go more in-depth than a typical AP Physics course would. Our target is to study elementary physics in proper breadth and depth, over three-year period. The problems we consider mostly come from old Moscow physics competitions and other classical Soviet sources, which I have been adopting for this purpose.

During my academic career, I taught [different flavors of] calculus at Yale, and University of Waterloo.

My system of preparation for the SAT/ACT math is "unique" (not really; it just imitates the way professional mathematicians approach math problems). First of all, slow down! "But I need to do it fast on the test," you may protest. True, but you need to learn how to *solve* problems first, *before* you can do it fast. The first time I looked at an SAT test, I did it (perfectly) in just over half the time--but I had never trained for speed. It may sound counter-intuitive, but speed comes naturally to those who (1) are good at solving problems and (2) have a complete command of the subject matter.

The good news is that the subject matter to master for the SAT math is very VERY limited. It can be explained to a thoughtful 7th grader. I had done that with my 12-year old son, who went on to score 790 on the SAT Math in May of 2012 (in 7th grade) and 800 in October 2012 (in 8th grade). I can do this with you, too.

How can I teach you to *master* the SAT math? By asking you to 'throw out the clock' and take your time; to write your complete solutions in a quad-graphed journal; to cover up the multiple-choice answers, unless the problem cannot be solved without seeing them. This approach to problem solving will immediately flash out the areas in need of additional attention. This is the most efficient way--perhaps the only way--to truly master the subject matter, and to end up *dominating* the test.

It is only when you have mastered the SAT problem solving *without* the clock--and you will, sooner than you may think--can we begin worrying about speed. But guess what: at that point, it will scarce be necessary.

As a Statistical-Arbitrage trader on Wall Street, I am a de facto practicing statistician. Being a professional mathematician (Yale Ph.D.) certainly helps. Last spring, I tutored an exceptionally gifted 9th-grader, who proceeded to score 5 on the AP exam.
