Charles

College, Test Prep, and Python Tutor: GRE, GMAT, MCAT, Data Science

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 an 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 ...

Susan T. from Brooklyn, NY

Really awesome tutor. Very organized and can answer all my questions very well. Knows the material very well, too.


Crystal A. from Brooklyn, NY

Charles P is a wonderful chemistry tutor. He is very patient and extremely thorough, hence he is able to make difficult subjects such as chemistry, well, not so difficult. His ability to convey such a puzzling subject in an elucidating way is applaudable. He has been my tutor for almost two months now and I am pleased with his level of teaching and professionalism; I am also satisfied with my progress.


Debbi B. from Stamford, CT

Charles was so helpful to me during my semester of chemistry. He was able to make complex topics easy to understand. It was a pleasure working with him.


Becky K. from Great Neck, NY

Charles is an excellent tutor! He is very polite, very professional, and very knowledgeable. I worked with him for several months on college level-Calculus 2, Physics 2 and Statics. He is very patient with his students, and will spend as much time as is needed to ensure understanding. He is exceptionally good at explaining complicated things in a way that’s easy to understand. He shows you how to organize your solutions to problems by breaking everything down into a set up easy-to-understand, methodical steps. He will help you work through all the problems logically. Rather than just showing you the solution to the problem, he works with you step by step and gives you hints so that you can work it out, yourself. This really helps to truly understand the problems, how they work, and the proper way to solve any similar problem. He was always prepared for each session, with example problems from other texts to cover during the session, along with some additional problems to practice on your own. He is always determined to make the most of the tutoring session, and remains focused on the subject. I VERY highly recommend Charles for any subject. He is an excellent tutor, and a great person.


Michael S. from New York, NY

Charles is a very professional and knowledgeable tutor. He is prompt for appointments and covers all of the materials required. His thorough and understandable explanations for questions and concepts in a very difficult subject make learning easy.


Van W. from New York, NY

Charles is a great tutor. He is patient and explains the work so well that he makes a once hard problem seem easy. The tools and tips he provided for doing well on the GRE were invaluable.


Louisa L. from San Francisco, CA

My son was so amazed with the immense help he received from Charles P. during their first tutoring session in Organic Chemistry. Thank-you, Charles!


Randall I. from New York, NY

Charles is patient and supportive, but also thoughtful. He is helping our son feel comfortable that he can manage the physics work he did not think he could do. He is also practical about what can be accomplished in the time available and how to be strategic in working through the lessons. We are very pleased. Feb 10, 2014 The physics course that Charles was tutoring our son to complete has ended. We did not rate each lesson, as it was unnecessary. He was unfailingly supportive and professional. He helped our son manage virtual labs, prepare for quizzes and prepare the work in each unit. Thank you for your help.


Rachel M. from Yonkers, NY

Great tutor. Very patient, went through all of the material I needed to learn. He helped me understand the concepts as well as worked through some practice problems I had. Excellent tutor, I would highly recommend Charles.


Jackie S. from Port Washington, NY

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 very patient and takes great care in understanding how each of his students think to give them the best chance of understanding the information. He came to each session prepared with examples to increase my understanding of the subject. Not only is he thorough, but he also made me very comfortable asking questions and gave me a lot of encouragement along the way. I am so glad I found Charles to get me through this class. If you are in need of a tutor, I highly recommend Charles for the job!


Robin R. from Brooklyn, NY

Charles went through my practice exam with me, and helped me identify concepts to study further on the Quantitative Reasoning portion of the GRE. He then helped me create an action plan for further study until my real test. Exactly what I needed and I feel very confident!


Naoko I. from Michigan City, IN

Although it was year-end, he was very fast to respond to my emails, and scheduling was easy. He was extremely knowledgeable in the subject and provided the study material. Very professional and efficient. Highly recommend!


Steven D. from New York, NY

Needed a tutor stat for my 9th and 11th grade year old sons. Physics, calculus and Algebra required some brushing up. Charles is easy going, and my boys enjoy working with him. Now cruising thru exams


Mary N. from New York, NY

Definitely knows his physics. I've only had one session with him for MCAT physics and will update, but so far so good!


Greta B. from Saint Louis, MO

Charles very clearly knows what he is talking about and is able to put together a very fluid and thorough lesson plan. I was very pleased with his tutoring abilities!


Mahathi K. from New York, NY

I have been working with Charles for the past month for GRE math tutoring and have learned new concepts that are useful for both testing and everyday math. I look forward to our sessions and genuinely enjoy his teaching method. He motivates and challenges me while also being patient. I highly recommend Charles to anyone seeking an attentive and fun tutor!


Adam R. from Cape Coral, FL

Not only does Charles explain everything thoroughly, he provides several different approaches to attack the information as well as sample problems. I'd definitely recommend him to anyone struggling with Organic Chemistry 1 or 2. An excellent tutor!
