Improving Students Division
(geared for 4th and 5th grade)

This section is for students just starting their journey in competitive math and looking to hone their fundamentals.

Elementary Masters Division
(geared for 4th and 5th grade)

Looking for an even more challenging set of problems? This section is perfect for elementary students who want to stretch their mathematical abilities!

Smooth and Steady Senior Division
(up to 8th grade)

Most middle schoolers will find this division the most appealing. There will be a wide variety of problems ranging from straightforward to very challenging!

Genius Division
(up to 8th grade)

When we say "genius," we mean it! There are no straightforward problems and only a few medium level problems. This section is for students who aren't afraid to tackle hard questions under time constraints.

Software Engineer Division
(adults, ages 21 and above)

Parents get to play too! The questions will be hard, but it will be a great brain exercise for 60 minutes. Any adult can enroll in this division (you do not have to be a software engineer!).

Why do students love HCMMC?
It's challenging.

From 2021 to 2024, the average of the top three scores in the student divisions was just over 6. Over these four years, nobody in the Genius Division has even scored higher than 6!

It's fun.

Attempting to solve 12 problems in only an hour is crazy, but it's also really fun because there's no pressure and the problems are hilarious.

Pick your division.

Students get to choose the division that best suits their math experience level.

Brownies!

Mr. G. baking brownies for a math event? 'Nuff said.

Why do parents love HCMMC?
Challenging questions.

All divisions have at least three really hard problems, so students will learn to budget their time according to what they can reasonably finish in 60 minutes. If they make it through the first nine problems, the last three will offer a substantial challenge!

It's free!

Mr. G. and the executive team organize the event and write most of the problems. The City of Cupertino provides the space, the Math Olympiads TAs proctor the contest and grade them, and Mr. G. and the Chen family provide snacks and awards. Harrison would have liked it this way, so that's the way we've always done it.

In memory of Harrison Chen...

Harrison Chen was a gifted student who attended Palo Alto schools through 9th grade until his untimely death during November of 2015. In honor of his contibrutions to the class, the staff of Cupertino Math Olympiads began to organize an annual math competition in his memory.

At HCMMC, we celebrate Harrison's life and the joy of problem solving. The mood will be upbeat. Please join us!
