The China Mathematical Olympiad (CMO) is one of the highest-level mathematics competitions for secondary school students in China, organized by the Chinese Mathematical Society. Commonly known as the National High School Mathematics Winter Camp, CMO serves as a major stage in the selection process for China’s national mathematics training team and brings together top-performing students from across the country.

Competition Format

CMO is typically held once each year, with qualification primarily based on outstanding performance in the National High School Mathematics League competitions. The competition usually lasts two days and consists of multiple highly challenging proof-based problems covering algebra, geometry, number theory, combinatorics, and related advanced mathematical topics. The competition emphasizes rigorous proof-writing, deep logical reasoning, creativity, and advanced mathematical problem-solving ability.

Skills Development and Competition Value

CMO helps students significantly strengthen advanced mathematical thinking, analytical reasoning, abstract problem-solving, and proof-writing skills. Preparation for the competition requires systematic study of Olympiad mathematics and extensive experience solving highly difficult problems. CMO is regarded as one of the most prestigious academic achievements within the Chinese and international mathematics competition systems, especially for students interested in mathematics, theoretical computer science, and other highly quantitative STEM disciplines.

Role in University Applications

Participation in and strong performance at the China Mathematical Olympiad demonstrates exceptional mathematical talent and academic potential. For students planning to apply to competitive programs in mathematics, computer science, artificial intelligence, engineering, physics, economics, and related STEM fields, CMO achievement is considered highly valuable. In applications to top universities in China, the UK, and the US, CMO serves as strong evidence of advanced analytical ability, intellectual depth, and high-level academic competition experience.
