CM700 – Introduction to Olympiad Math

Description:This class is intended for students who have been active in math competitions for a few years but are relatively new to Olympiad Math (proofs). Students will learn how to write proofs and learn more in depths topics and techniques to transition from AIME type of problems to USA(J)MO type of problems. In terms of difficulty of problems solved in class we will be focusing on and solving USA(J)MO-level Olympiad problems and various competitions from around the world. CM700 helps students improve their USA(J)MO scores.

Who should take this course? Students who wish to enroll this class are expected to have qualified for the USA(J)MO in the past.

Homework: 2 Olympiad problems are assigned to each student to solve and upload on Canvas each week. Students are expected to spend about 5-6 hours per week outside the class to prepare for the online meeting and to finish the homework after the meeting.
