Kevin's profile
Kevin
University of Pennsylvania
I am a graduate from the University of Pennsylvania where I received a Bachelor of Arts in Chemistry. I started peer tutoring in high school, staying after school to help fellow students with AP Chemistry content before major exams and quizzes. I currently tutor in math (up to AP Calculus BC/Calculus II), chemistry, physics, biology and offer test prep for the SAT and several SAT Subject tests. However my favorite subjects to tutor involve chemistry, due to the various real world examples that make the subject more comprehensive and ultimately enjoyable for students. My hobbies and interests include dancing, solving crossword puzzles, binging Netflix TV shows and hiking.

From my experience teaching math to a range of students, from middle school through college, I know that it does not come easily to everyone. However, I firmly believe that everyone has the capability for mathematical reasoning. Everyone has their own strengths and challenges, and my job as a tutor begins with identifying these. I like to have students work through problems while I guide them and make suggestions, so that I can get a sense of what they understand and what they don't. Then we can build on their knowledge and break down the challenging parts of the problem into smaller, more manageable chunks. I hold a bachelor's degree from UChicago and a doctorate from MIT, both in mathematics. I am available to tutor Latin, physics, and all levels of math. Outside of academics, I am an avid tournament chess player, and I enjoy running and cycling.

Princeton University
Math has been my passion ever since high school - from earning 1st place nationally in Calculus and Linear Algebra, to competing on the AMC 10, AMC 12, and AIME exams. At Princeton, I tutored peers in Multivariable Calculus, and since then I've worked with middle school through college students in Geometry, Precalculus, Trigonometry, Calculus, and SAT/GRE quantitative prep. I'm dedicated to simplifying complex ideas and helping students build confidence in their own problem-solving skills! I also built my first artificial intelligence tool in 2018, and currently enjoy helping integrate LLMs and Agents for companies!
