Courses in School Enrichment (SE) Series build students' understanding of the concepts they are likely to encounter in general school curriculum with extra depth and breadth. SE Series courses are Algebra 1 (ALG1), Geometry (GEO), Algebra 2 (ALG2)

Courses in Accelerated Championship (XC) Series intend to improve top level young students' command of the core knowledge leading to higher studies in mathematics. XC Series courses are XC7, XC9, XC10.
From 2000 to 2022, the Phillips Exeter Academy Red Lion (PEARL) math club/team, under the supervision of IDEA MATH academic director Dr. Zuming Feng (joined by IDEA MATH staff member Ivan Borsenco more recently), has become a dominant force in US high school math contests. Students from PEARL have diverse backgrounds, skillsets, and personalities. What do they have in common? Well, almost all of them have studied PEA Math Transition 3X (or 31X-40X-41X) and PEA Math 431-511-521. The materials in the XC Series build upon materials that Zuming has used for these PEA courses. Courses in the XC series are designed to improve students' command of the core knowledge, leading to higher studies in mathematics. Students will be surprised to discover that the school curriculum could be as challenging and as useful for preparing for higher-level contests (such as AMC 12/AIME/ARML/HMMT/USAJMO/USAMO), if the right problems are posed, and more importantly, the school curriculum could and should be far more important, if learned with good depth and breadth. While math contests are not the main focus for these courses, these courses cultivate young talented math students’ vision on the flow of mathematics and the ability to reason and argue mathematically and rigorously. Therefore, students’ achievements in math contests tends to follow as a natural result.

Courses in the Contest Edge (CE) Series are intended to be supplementary courses to courses in the SE, EC, XC, and MO series. These courses provide additional preparation opportunities for various math contests such as MATHCOUNTS (School, Chapter, State, National rounds) and American Math Competitions (AMC 8/10/12, AIME, USA(J)MO). Materials in these courses are oriented by subject and topic. The CE Series courses are CE1 to CE10.

Courses in Extra Curricular (EC) Series are designed for students pursuing extra curricular mathematics far beyond general school curriculum and provides extensive preparation for contests such as MATHCOUNTS, AMC8/10/12, and AIME etc. EC Series courses are PC0, PCA, PC1, PC2, PCX, UC1, UC2, UC3

Courses in the Math Olympiad (MO) Series focus on systematic development on math reasoning skills to prepare for math olympiads. The MO Series courses are MO1, MO2, MO3, MO4, and MO5.
From 2000 to 2022, the Phillips Exeter Academy Red Lion (PEARL) math club/team, under the supervision of IDEA MATH academic director Dr. Zuming Feng (joined by IDEA MATH staff member Ivan Borsenco more recently), has become a dominant force in US high school math contests. In this period, students from PEARL have been USAMO winners more than 45 times and have won 27 IMO gold medals, 11 silver medals, and 8 bronze medals. The materials in the Math Olympiad (MO) Series build upon materials that Zuming and Ivan have used for PEARL math club activities and the US Math Olympiad Summer Program (MOSP) entry level courses.

Courses in the Winter Contest (CW) Prep Series are intended to be supplementary courses to courses in the SE, EC, XC, and MO series. In each course, materials for the CW Series are different from year to year. Courses in the 2022 CW Series will focus upon Contest Review 2022: selected high-quality problems from US math competitions (such as AMC 8/10/12, AIME, USAJMO/USAMO, MATHCOUNTS chapter, ARML, HMNT, HMMT) and around the world from 2012, 2002, and 1992. These courses also feature about 16 new (original) practice sets (covering all different levels) written by our academic team.
