MD

This course gave me the best understanding of middle school math than I ever had!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!.

OL

Although I have been pretty good at math, I had not been enthusiastic about learning competition math until I took this course. Previously, competition math appeared to me to be incoherent and therefore not beautiful. There were always some kids who were willing to have more training and were so much better than me. Since I didn't like to take tutoring for competition math, I saw little point to pursue competition math. On the other hand, school math is too easy for me. This course shows me math is beautiful and interesting, and piques my interest in working on challenging problems.

DW

I like how you condense it so understanding it is easy. The fact that it has many different solutions are also cool with different hidden concepts.

CD

This course was clear and amazing and easy to understand

JZ

These daily challenges are very good for helping you think better.

JH

I really liked the explanations, and although I got all of them correct, I learned lots of new things! This course is really interesting
