TWMC  Math Olympaid (TWMCO)


About TWMC Math Olympaid (TWMCO)

TWMCO exams and scoring criteria are authorized for use by the Bay Area Math Olympiad (BAMO). BAMO is a highly renowned math competition in the San Francisco Bay Area, co-founded by Zvezdelina Stankova and Paul Zeitz of the Mathematical Sciences Research Institute (MSRI), and organized jointly by the Berkeley Math Circle (BMC) and other math organizations. Known for its depth and challenge, BAMO attracts many Olympiad contestants and Math Circle participants. The competition covers middle and high school levels, with two divisions: BAMO-8 and BAMO-12, each consisting of 7 problems to be solved within a 4-hour time frame. It typically takes place on the last Tuesday or Wednesday of February each year.

The authorization for TWMC to use BAMO exam questions is a great honor. Our aim is to provide Taiwanese students aspiring to participate in the International Mathematical Olympiad (IMO) an opportunity to gauge their level of proficiency, serving as a pre-competition test for future Olympiad challenges. Additionally, we offer students who enjoy tackling challenging problems and Math Circle participants a chance to participate in the prestigious BAMO alongside American peers. Proceeds from this competition organized by TWMC will be donated to charitable organizations, and schools setting up examination centers can participate free of charge.

Rules of BMC Montly Contest


There are two categories: TWMCO-8 and TWMCO-12.

Both exams consist of 7 questions to be completed within a time limit of 4 hours. Questions in TWMCO-8 are labeled A, B, C, D, E in increasing order of difficulty. TWMCO-12 questions are numbered 1-5, also in increasing order of difficulty. Generally, the last three questions of TWMCO-8 overlap with the first three questions of TWMCO-12, meaning that problems C, D, and E in TWMCO-8 correspond to questions 1, 2, and 3 in TWMCO-12.

TWMCO-8: Middle school second grade and below.

TWMCO-12: High school second grade and below.
