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.

Olympiad "secret" and "spontaneous" events such as flash mobs. The English term is still often used popularly to indicate the games themselves, a usage that is uncommon in ancient Greek (as an Olympiad is most often the time period "between" and including sets of games). It is also used to indicate international competitions other than physical sports. This includes international science olympiads, such as the International Geography Olympiad, International Mathematical Olympiad and the International Linguistics Olympiad and their associated national qualifying tests (e.g., the United States of America Mathematical Olympiad or the North American Computational Linguistics Olympiad), and also events in
