About Zachary

Bio

My specialty is breaking down questions that may seem complex at first glance and making them accessible to everyone. I aim to impart understanding more than anything; I take a patient approach with my students and go through any given problem methodically. Whether you are already interested in math and want to level up, or haven't taken a math course in ten years and need to study for the GRE, or simply need to boost your test scores in all areas for your college applications, I am here to...

My specialty is breaking down questions that may seem complex at first glance and making them accessible to everyone. I aim to impart understanding more than anything; I take a patient approach with my students and go through any given problem methodically. Whether you are already interested in math and want to level up, or haven't taken a math course in ten years and need to study for the GRE, or simply need to boost your test scores in all areas for your college applications, I am here to help you.

I have taught all levels of math, test prep, and writing one-on-one since 2016. In that time, my students have ranged in age from sixth graders to mid-career professionals. They have often comprised NYU undergrads who need to knock out their math requirements, professionals looking to get their MBA but who need a refresher on math for the GRE, and high schoolers preparing for their ACT / SAT / math classes / math contests / college applications.

I got my Bachelor of Science in mathematics from Brown in 2015. I live in Brooklyn and will tutor either online or in-person within NYC. Relevant scores: 35 ACT, 2280 SAT (out of 2400; 800 R / 770 M / 710 W), 340 GRE (perfect). AP 5s: AB/BC Calculus, Statistics, English Language, English Literature, US History, Chemistry. I also qualified for the USA Mathematical Olympiad in 2010.

Approved Subjects

ACT English

ACT English

I got a 35 on my ACT (35/35/36/34 breakdown) and have tutored many ACT students since 2016. The ACT is probably the single most common subject I've taught, and I often see 4-5 point improvements in my students. I aim to combine common test-taking strategies with imparting real understanding in my students.

AMC (Competition math)

AMC (Competition math)

I have extensive experience with middle and high school math contests. I qualified for MATHCOUNTS Nationals in 8th grade, AIME 10th-12th grade, USAMO 11th grade, and ARML all four years of high school, with top scores in AMC 8 and 12. I've also worked with middle and high school students on contest math, and commonly use Art of Problem Solving materials with my students.
Calculus

Calculus

I got 5's in both the AB and BC calculus AP tests, and also got A's in mutivariable calculus courses in high school and at Brown. Several of my high school and college students have worked with me for either single- or multivariable calculus. I take a patient approach and break down complex concepts to make them accessible.
Chess

Chess

I am rated around 1700 USCF. I've been playing in scholastic events, club events in NYC, and online for more than 20 years. In addition, I've taught various subjects including all levels of mathematics and standardized tests since 2016. I am ideally suited as a coach for players rated up to 1300.
Discrete Math

Discrete Math

I took a course entirely about discrete math at Brown. In addition, I participated in math contests throughout high school where many of the problems related to discrete math. This is a subject I know in great detail.
Geometry

GRE

GRE

I got a perfect 340 score on the GRE, and have tutored the GRE for many students since 2016. My students often achieve 10+ point improvements in their composite scores, and have gotten into graduate programs at schools such as Harvard and NYU Stern.
Linear Algebra

Linear Algebra

I got my bachelor of science in mathematics from Brown in 2015, and took linear algebra courses in both high school and college, getting A's in both.

In-tune and highly knowledgeable for an accelerated student

Zachary has been an exceptional tutor for my accelerated student! Not only is he highly knowledgeable to cover the top-level math problems on the SAT's, Calculus BC, and bonus - he can help with SAT's verbal, too! But what really makes him stand out is that he is in tune with my son. It's hard to find both of these qualities in a tutor! He flexibly listens and can identify gaps and learning needs. I could not ask for more. If you have a kid who is capable of top scores if given the right instructor, I can't say enough about Zachary!
