“Charles has been a terrific tutor for my 17-year-old daughter in AP Chemistry. He reviews the material in a manner that is easy to understand and fosters a positive learning environment. My daughter’s ability to comprehend the material has increased greatly since Charles has been assisting her. Her grades show that as well. Charles makes scheduling easy and is always accessible for questions. We highly recommend Charles!”

— Whitney, 1 lesson with Charles
“Charles is a very careful, methodical teacher who takes the time to explain the material at hand in a detailed manner. Whenever there’s a concept that evades understanding on the first attempt, he finds a way to break it down into it’s simplest building blocks to make it as digestible as possible. Couldn’t recommend him any more highly.”
— Leland, 760 lessons with Charles
“Charles virtually tutored me and a classmate in Machine Learning. I had tried out other tutors for the subject and was coming across a lack of knowledge on the topic and professionalism. Charles, literally, came prepared not only to help complete assignments but to teach and inspire as well. Charles went above and beyond not only to accommodate schedules but answer questions and get a good understanding of Machine Learning/Data Science. I genuinely believe that without Charles's help I would have dropped the class, but he gave me the confidence to focus and keep going. Very lucky to have found him and couldn't give higher praise!”

“Charles is amazing. He has been helping me perfect my Python programming skills and understanding of the concepts. In this day and age of distance learning, he provides customized and detailed instruction of the ins and outs of programming. When I have specific questions on a topic or need a more detailed explanation of how something works, he does not hesitate to go above and beyond any expectations. Without his tutoring sessions, I would be nowhere near as proficient in Python as I am now. 10/10.”

“Charles was very practical in his approaches to scoring well on GR. His mastery of the quantitative problems was very impressive and he made me feel that I could also master them. He worked with me to focus on how to improve my score to achieve my score goal. I would without a doubt recommend to anyone committed to studying for the GRE. I had only two sessions with Charles and saw my score improve by 6 points on the quantitative section. I intend to schedule 2 or 3 more lessons before my test date. Thank you Charles!”

“Charles really knows his stuff, and imparts it well. I've used him for two subjects: Calculus III and Statics. For Calculus, he made Series/Sequences, a topic typically dreaded by students, less stressful by explaining when to use which tests in an easy to understand fashion. For Statics, he explained things that my professor didn't, describing importance of defining line of actions, and even more conceptual aspects of the course material. I highly recommend him!”

— Christine, 5 lessons with Charles
“I presented charles with a worksheet given by my professor and he was able to work through the entirety of the worksheet with me without any stumps along the way. He was able to clearly identify all of the necessary steps in a very simple manner. I was not able to complete the worksheet on my own before the session, but after the session, I was able to complete it fully and got a much better understanding of the concepts (much better than I would've if I was to continue to attempt them on my own). Also, his notes are very organized and helpful!”

— Robin, 1 lesson with Charles
“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!”
— Jackie, 29 lessons with Charles
“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.”
— Rachel, 1 lesson with Charles
“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.”
— Randall, 17 lessons with Charles
“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!”

“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.”
— Michael, 2 lessons with Charles
“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.”
