The International Mathematical Olympiad

The International Mathematical Olympiad is the World Championship Mathematics Contest for second level students. Each country is invited to send a team of up to six students to compete in this contest. The competition itself involves tackling very difficult mathematical problems which require a great deal of ingenuity to solve. Participation alone in this competition is regarded as very prestigious. Indeed, many of the world's leading mathematicians are past participants of the IMO.
