The Asian Pacific Mathematics Olympiad (APMO) starting from 1989 is a regional mathematics competition which involves countries from the Asian Pacific region. The United States also takes part in the APMO. Every year, APMO is held in the afternoon of the second Monday of March for participating countries in the North and South Americas, and in the morning of the second Tuesday of March for participating countries on the Western Pacific and in Asia.
The APMO contest consists of one four-hour paper consisting of five questions of varying difficulty and each having a maximum score of 7 points. Contestants should not have formally enrolled at a university (or equivalent post-secondary institution) and they must be younger than 20 years of age on 1 July of the year of the contest.
The APMO is about as difficult as the USAJMO.
