The Acton-Boxborough Math Competition (ABMC) is a competition designed for middle school students across MA.

We accept teams of 2-4 students as well as individual competitors.


ABMC is uniquely designed such that every participant can solve a sizable portion of the problems. The difficulty ranges from that of simple arithmetic, algebraic, and geometric problems to that of the AMC. All participants will have problems they can solve and problems that will challenge their mathematical problem-solving skills.

Additionally, ABMC provides online contests that are free.

If you have any questions or would like to sponsor us, please do not hesitate to contact us!
