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.
