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. The best
Indian National Mathematical Olympiad attend the IMO Training Camp are sent postal problems during the period July -- December that they have to solve and send back (if they are still in school). Based on their responses, some of the students are invited to the IMO Training Camp the next year directly. Others have to rewrite the INMO again (they do not have to write the Regional Mathematics Olympiad). Indian National Mathematical Olympiad The Indian National Mathematical Olympiad (INMO) is a high school mathematics competition held annually in India since 1989. It is the second tier in the Indian team selection procedure for the
