At Columbia University, I took advanced courses in calculus and physics. I teach advanced mathematics, physics, and finance regularly. Subjects taught include competition math including AMC 8, 10, 12, algebra I, algebra II, geometry, trigonometry, precalculus, calculus I, II, and III, AP Calculus AB, BC, linear algebra, and differential equations, SAT Math Level 2 and AP Physics. I also prepare students for the Math SAT, ACT, GRE, and GMAT. I also teach financial mathematics and financial derivatives.

I teach advanced mathematics and problem-solving techniques to prepare middle and high school students for mathematical competitions including the Math Olympiad, AMC 8, AMC 10, AMC 12, MATHCOUNTS, Math League, Mu Alpha Theta, etc. Specific topics include number theory, counting, probability, geometry, proofs, logarithms, conics, and polar coordinates, polynomials, functions, quadratic equations, complex numbers, vectors and matrices, cross products and determinants, analytic geometry, inequalities, combinatorics, sequences, and series, modular arithmetic, etc.

I specialize in test preparation for the SAT, ACT, GRE, and GMAT exams. I am very familiar with these exams. I quickly find gaps in student knowledge and then customize the instruction and lesson appropriately. I teach intuitively, providing many examples and explanations. With my proprietary methodology, I can help the student score higher with practice.

At NYU Stern, I took advanced courses in finance. I teach finance to graduate and undergraduate students. Subjects taught include financial mathematics, financial derivatives, options, fixed income securities, and corporate finance.

Knowledgeable and Enthusiastic

Both my daughters have been taking lessons from Ephraim recently. He is a very enthusiastic teacher and knows how to create interest in mathematics. He has a fun and unique way of teaching. Both my kids enjoy their classes with him and look forward to the next one. I would highly recommend him.

Extraordinary GMAT tutor

Ephraim is an extraordinary GMAT tutor. He’s the right tutor for the business school applicant who fits any of the following criteria: 1. Values their time and wants to approach the GMAT as efficiently as possible 2. Hasn’t done math since high school and needs to revisit the fundamentals 3. Is seeking a perfect score Ephraim breaks things down so that you understand WHY the answer is right. He’s been teaching math so long, and from so many different perspectives, that he knows the best/fastest way to teach any topic you throw at him. Plus, he’s super encouraging all the time and made relearning math for the GMAT a genuine pleasure. If for whatever reason I need to get good at math again, I’m calling up Ephraim.

Knowledge and dedication

Ephraim is the best math teacher I have even known. Having been teaching my high school daughter for about a year. It’s our fortune to have him in my child’s education experience. He’s knowledge, dedication, and passion is remarkable.

Ephraim is the Best

I have been relying on Ephraim to prepare me for the SAT (Math). He does an amazing job of analyzing my needs and then works with my to address them. Through working with him I am increasingly gaining confidence that will achieve my SAT goals of stick the program Ephraim has outlined for me.

Happy to have found Ephraim.

Ephraim is very organized and responsive, he took the time to find details and information that he would need to help my son be successful during the tutoring and in my son's math class, as well as competition math. My 12-year-old son enjoyed his first lesson and found the time spent with Ephraim extremely helpful. My son is looking forward to the next lesson with Ephraim.

Mr. Ephraim is a great fit for my children

I have been using Mr. Ephraim weekly for my daughters’ math tutoring needs. One is an advanced math student and the other is slightly above grade level. He fills the gap between their school lessons and where they need to be to be competitive with other ambitious students. He is patient, kind and conveys a genuine love of teaching mathematics. I can’t wait until my son is old enough for Mr. E. in a couple of years! He is a refreshing change from the uni. student math tutors, who tend to be fine for cramming for an upcoming test but aren’t up for giving a deeper treatment of math topics.

GMAT Prep

Ephraim is very kind and nice. He was able to identify my weaknesses and help me understand how I can go about overcoming them. I really appreciated his help. I definitely recommend and will use him to tutor me again!

Knows the material and makes use of time.

Who better to tutor a future engineer than an engineer who offers tutoring tailored to the student. His friendly and outgoing personality motivates my student to want to do well. He makes a point to discover the students strengths and weaknesses and strives to fill in the gaps, so the student has a full understanding of the material. The white board is an excellent tool to see what the student is reviewing online. I could never find a tutor of Ephraim's caliber in our small town.

Enthusiastic Thumbs Up!

Generous with his time. Exercises great insight and patience for hard subject matter. He provides both the 30,000 foot view of a subject as well as the minute details with seamless command.
