Washington, D.C. (August 3, 2021)-- Team USA, sponsored by the Mathematical Association of America American Mathematics Competitions (AMC), earned fourth place in the virtual 62nd International Mathematical Olympiad (IMO) held on July 14-24, 2021. The six high school U.S. team members also won medals for their individual top scores.

The IMO, the preeminent high school math competition, brings together the top mathematics students from across the world to compete in the world championship of math. Similar to the 2020 IMO, this year’s competition was virtual with each country setting up their own exam centers and live streaming the participants as they took the competition. This year five US team members were scattered around the US in 5 different venues, across 3 different time zones, and one US team member sat for the IMO in Macau.

This year, 107 countries and territories participated in the virtual competition hosted by the Russian Federation. The U.S. team scored 165 points for a fourth-place finish. China won first place, Russia placed second, and South Korea placed third in the overall team scores. IMO scores are based on the number of points scored by individual team members on six problems.
