About

Hi, I’m Leo!

I love teaching math and physics, especially AP Calculus, AP Statistics, and problem-solving strategies from competition math (3x AIME qualifier). I’m also experienced in AP Physics and enjoy breaking down tough concepts into simple steps. Since I grew up in Korea, I’m fluent in Korean and can teach bilingually if that helps learners. Outside of academics, I’m a clarinetist and pianist who mentors younger musicians, so I know how to explain things patiently and build confidence.

He made sure everyone understand the topic. It really helped me develop strong foundations for logarithms. It was interactive and he was patient until everyone understood. One of the best tutors I've seen.

I learned so much about Complex Numbers from Leo L! I learned about many rules from him. His method of teaching is very easy to understand and he makes learning fun! He makes these classes feel even more worth it because they are free! He was very patient, and answered my questions in a very comprehensible manner. I'm looking forward to my next class with him.
