Overview
The Hong Kong Mathematical Olympiad (HKMO) is a school-based maths competition for secondary schools in Hong Kong. It is organised jointly by the Mathematics Education Section of the Education Bureau and the Department of Mathematics and Information Technology of the Education University of Hong Kong. The 2025/26 edition was the 43rd, and past papers back to 1983/84 are published for download.
