Description: The USAMO and USAJMO are proof-based problems. In each of the two 4.5-hour sessions contestants are given three problems. All answers must be clear in logic; numerical or incomplete answers will receive no or partial credit. The top performers will be invited to the Mathematical Olympiad Summer Program (MOSP or MOP). Then six elite students will represent the USA at the annual International Mathematical Olympiad (IMO), the toughest math competition for high school students.

Achieving qualification for the USAMO or USAJMO is a remarkable accomplishment, as only approximately 500 students nationwide are selected to participate.
