MCCT

PROBLEM ARCHIVE

Each Sunday, the Math Circle Competition Team (MCCT) meets to practice competition mathematics. Below are our lessons, problem sets, and solutions since 2016, covering a wide range of topics in competition math. Some solutions will not be posted  because we want our current students to discover solutions on their  own. Cited problems may have online solutions. Visit   the AOPS Community to discuss some of the problems, or e-mail us for help at mcct@mathcircle.us.
