About Charles

I'm a graduate of Princeton University with a passion for teaching. I quite simply enjoy leading students through difficult course material and preparing them for standardized exams. I believe that learning is a ongoing process and that tutoring should make that process more manageable.

My tutoring services mainly focus on test preparation. Scoring in the 99th percentile on the math and chemistry sections of the GRE, GMAT, MCAT, SAT, SAT Subject and AP exams, I have also obtained high combined scores in the math and verbal sections of the SAT (99th percentile) and GRE (98th percentile) exams.

Tutoring for over 6 years, I credit my success to a single philosophy: above all, I try to instill confidence in my clients by helping them manage their academic workload. In every lesson, I negotiate their expectations while also putting them in the best possible position to succeed. Beyond providing customized worksheets and study guides, my services reduce stress levels and increase sustained focus. Consequently, my sessions are known to be very productive.

My services also cover college/high school math and science courses. Since I have extensive experience working with local students attending Columbia, NYU, Hunter, and other CUNY schools, I am quite familiar with the testing style of specific professors.

Lastly, I am flexible with times and meeting locations. I work as a full-time tutor, so scheduling is rarely an issue. I mainly tutor within Manhattan, but also conduct lessons in Queens or Brooklyn, if my workload allows it. I also enjoy working online whenever students are unable to meet in person.

Approved subjects

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.


Chemistry is one of my favorite subjects to tutor. Ever since taking AP Chemistry in high school and Advanced Chemistry in college, I have gained an appreciation of the work required to master the course. Whether teaching stoichiometry, periodic trends, or kinetic molecular theory, I help students effectively learn complex concepts in a short period of time.


I'm an expert in standardized math test preparation, having recently scored a 50 on the GMAT's quantitative section. Being quite confident in my approach to the exam format (e.g. data sufficiency), I routinely employ methods that maximize time and content knowledge to achieve the highest score possible. Beyond that, I have access to a number of GMAT question banks, which have been helpful to dozens of clients over the years.


I scored in the 98th percentile (Q:163 V:163) of the GRE. I mainly tutor the quantitative section, but I'm fine with discussing strategies and techniques used for both sections. Below you'll find answers to frequently asked questions, but feel free to contact me for any additional information.

1) How much can I expect my score to increase?

Students who start tutoring with me at least one month prior to their exam date tend to improve their quantitative score by more than 8 points.

2) What resources do you provide?

I provide standardized material from a range of test prep companies, including the official ETS material. I also hand out practice worksheets and study guides for review after each session.

3) How do you plan out sessions?

During the first few sessions, I try to assess a client's comfort level with the material, reviewing past exam results and asking diagnostic questions. I then create a study plan, picking the topics and strategies I feel will most likely boost test scores in the shortest period of time.

4) How do you conduct each session?

I spend the first part of each session answering questions about practice problems. I then try to drill though specific math topics as we work through setting up increasingly complicated exam questions.


With years of experience working with college chemistry and physics students, I specialize in tutoring the Physical Science section of the MCAT. Many of my clients have seen a significant improvement in their scores. My approach starts with a general review of high yield concepts and then progresses to a more focused discussion of test-taking strategies, including ways of reading through passages efficiently, performing mental math tasks, and selecting the most appropriate formula for any given question.

Mechanical Engineering

I have a BSE degree in Mechanical Engineering from Princeton University. As a tutor, I specialize in statics and dynamics. In the past, I've successfully tutored engineering students at Harvey Mudd and Case Western.

Organic Chemistry

Organic chemistry is a tricky course. It starts off simple enough, reviewing topics like orbital hybridization, line angle structures, and IUPAC nomenclature. However, when the class starts integrating reactions into the discussion, students are usually overwhelmed by the amount of memorization required. At this point, the difficulty level in Organic Chemistry I increases exponentially and it keeps rising through Organic Chemistry II. Once students fall behind, it's quite challenging for them to solve multi-step synthesis problems, to draw out mechanisms, and/or to memorize reagents confidently.

I have 3 years of experience tutoring organic chemistry students at Hunter, Columbia, and Stonybrook. I've developed methods of organizing reagents and mechanisms by using study guides and worksheets customized to suit college curricula. I've also devised study strategies to maximize study time and to reduce frustrations. A number of students have reached their academic goals using these study techniques.

I first contacted Charles over my winter intersession, after having to drop my Organic Chemistry 2 class the semester before. I had a serious mental block against Organic Chemistry and had tried other tutors with little success. This was going to be my last chance to pass Organic Chemistry and Charles made it happen. Not only did I pass, I got a B in a class that last semester I was failing. He is
