Math Challenge III

Course Description

The Math Challenge III course is for students who are qualified to participate in the AIME contest, or at the equivalent level of experience. The MC-III topics includes everything covered in MC-II with more depth, and the focus is more on various problem solving strategies, including pairing, change of variables, some advanced techniques in number theory and combinatorics, advanced probability theory and techniques, solid geometry, geometrical transformations, etc. Through the effective guidance and direction by our experienced teachers, students develop strong problem solving skills that make them perform well in contests such as AIME, ZIML, and ARML.

Course Terms

Math Challenge III is offered in four terms:

  • Summer, covering Algebra
  • Fall, covering Geometry
  • Winter, covering Combinatorics
  • Spring, covering Number Theory

We recommend that students take all four terms, but the terms do not build on previous terms, so they do not need to be taken in order and students can take single terms if they want to focus on specific topics. For more information about the topics covered each term, please click here.
