International Mathematical Olympiad selection process Olympiad. Although in principle students of the lower levels may be selected to go to the IMO, it generally takes many years before they can compete with students of the highest level or nivel superior. After the National Competition the twenty best students of each level are invited to the June Training Session where students undergo the IMO selection process. "Hrvatsko matematičko društvo" invites about 20 contestants who performed best at the national level (national level competition is separated by age) to the Croatian Mathematical Olympiad ("Hrvatska matematička olimpijada", HMO) which consists of 2 days, 4 problems each.

International Mathematical Olympiad selection process International Mathematical Olympiad selection process This article describes the selection process, by country, for entrance into the International Mathematical Olympiad. The International Mathematical Olympiad (IMO) is an annual mathematics olympiad for students younger than 20 who have not started at university. Each year, participating countries send at most 6 students. The selection process varies between countries, but typically involves several rounds of competition, each progressively more difficult, after which the number of candidates is repeatedly reduced until the final 6 are chosen. Many countries also run training events for IMO potentials, with the aim of improving performance as well as
