IMOCSEA

The INTERNATIONAL MATHEMATICS OLYMPIAD COMPETITION OF SOUTHEAST ASIA is an international competition in Mathematics for Kindergarten, six Primary Levels (Grades 1 to 6), four Secondary Levels (Secondary 1 to 4), and one Senior Secondary Level (Grade 11 & 12). It aims to promote excellence and proficiency in Mathematics through friendly global competitions and to promote Southeast Asia’s tourism, with the Philippines as the first destination, then Indonesia, Singapore, Malaysia, and other SEA countries to other country partners worldwide.
