The International Mathematics Olympiad (IMO) is the largest, oldest and the most prestigious scientific Olympiad for high school students. It is annually held in different countries. The first IMO was held in 1959 in Romania, with 7 countries participating. Now, over 100 countries from 5 continents participate in the IMO. The IMO Advisory Board ensures that the competition is held every year and the host country observes the regulations and the traditions of the IMO. In 2018, the 59th International Mathematics Olympiad would be held in Romania from 3rd – 14th July 2018.
Each participating country sends a team of up to six secondary students or individuals who have not entered University or the equivalent plus a team leader, one deputy leader and observers if desired. During the competition, contestants have to solve, individually, two contest papers on two consecutive days, with three problems each day. Each problem is of seven points. Gold, Silver and bronze medals are awarded in the ratio of 1:2:3 according to the overall result. A certificate of honourable mention is awarded to each student who obtains 7 points for at least one problem.
The Mathematical Olympiad Programme in India, which leads to the participation of the Indian students in the IMO is spearheaded by the Homi Bhabha Centre for Science Education (HSCSE) on the behalf of the National Board for Higher Mathematics (NBHM) which is a part of the Department of Atomic Energy (DAE), Government of India.
