I offer private tutoring in UCLA classes Math 3A, 3B, 3C, 31A, 31B, 33A, 61, 115A and 115B, among others. I also offer tutoring in high school classes such as AP Calculus or IB Math. If you are interested, send me an email.

Note: I will not privately tutor any student in a class for which I currently grade.


I made a youtube video about a beautiful technique in combinatorics called generating functions. If you are interested, here it is.

I have made some videos on TikTok about math. Check them out here.
