Who Is This Course For?

Are you taking any math class from 6th Grade Math through Algebra, and in the top 10% of your class? Have you never taken any professional math competition classes at levels above Algebra? If you answered Yes to both, then this class is for you. It is the best thing you can do to transform your potential.

Diagnostic Tests:

Will I understand?Will I learn new things?

Course Structure

This course contains 20 LIVE 1-hour video sessions, of which 16 are lessons, and 4 are exam review sessions that discuss the course's 4 practice 1-hour exams (homework). Each class is co-taught by 2 of our Stars. In total, there are over 150 problems.

Each lesson contains several problems which are meant to be unfamiliar to you, so that they inspire you to invent your own solutions. In our LIVE video class format, you propose your ideas, and we brainstorm together with you to construct a variety of alternative solutions using the class's own ideas. This actively involves you in discovering mathematics.

Each practice exam contains 20 problems, of which half are of average difficulty, and the other half are very challenging.

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.

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