Princeton grad/Berkeley PhD student with 10+ years of experience tutoring all college level math + SAT/ACT/AP prep

Going to a top university is tough, and learning calculus at a top university is even more tough! I have worked with Kubrat for one year, and he has become the most important factor in my mathematics education, inspiring confidence and ability that I didn't know I had. He always keeps me on my toes and makes sure I understand all concepts before moving ahead to problem solving. If you thought being excited for math tutoring was impossible, you should definitely try Kubrat, because he'll change your mind.

I’m with Kubrat for a year already. He tutored me classes ranging from Linear Algebra, Probability, to Calculus. Best teacher ever meet in my life. Saved my life for all quizzes and midterms! Got A in all classes tutored by him!

I've been working with Kubrat for more than a year, and through that time, he's proven to be an incredibly effective and helpful tutor that produces quick results. Excelling at multitask-teaching, he coached me through my SAT preparation, increasing my score in only a few months. While simultaneously helping with SAT prep, Kubrat has helped me to understand the core concepts, not just how to apply tools learned in the classroom. This has been invaluable for all the tests I've taken since, since questions often bring together multiple units and require intense understanding and problem-solving skills, not just knowing how to apply formulae. Knowledgeable in everything from high school mathematics to complex university courses (and way beyond!!), Kubrat is truly the best tutor we've found on any site, and his method of teaching certainly pays off.

I cannot say enough about Kubrat. As a college student I was extremely apprehensive about my math courses, he has taken my understanding to the next level. Not only is his expertise in the field phenomenal, his teaching style identifies nuances in your thought process & plugs them. He is always punctual, very flexible with scheduling & has no problems if you need to me taught the same concept repeatedly. A trait not my tutors have in common. I would definitely recommend him for high school and college courses. I have taken calc1,2 and multi variable calculus with him ; been absolutely fantastic!
