Iranian Geometry Olympiad (IGO) 2026: Online for Grades 7-12, 16 October

For school students in grades 7-12 from any country (levels for grades 7-8, 9-10 and 11-12; participants must be younger than 20 and not enrolled at a university) and for anyone at the free level with no limit on grade or age. The olympiad takes place on 16 October 2026: each level has 5 problems, and 270 minutes are usually given for the work. If a country has no official organizer, a student can take part individually: contact the organizing committee through the website, receive the problems at the specified time and send scans of the solutions in English; the committee sets a fee to cover costs. The awards are gold, silver and bronze rulers, and all participants receive certificates.
