• One Prerequisite Check

    The Prerequisite Check will see if you already have the basic tools you'll need to start to learn. The math that we talk about later in the class will be much more sophisticated and will build upon these tools.

  • Multiple Placement Tests

    There will be multiple Placement Tests, one for each Module. They will help you understand the math theorems and topics covered in the real Module courses.

“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. ”

“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.”
