The International Mathematics Competition for University Students (IMC) is an annual mathematics competition open to all undergraduate students of mathematics. Participating students are expected to be at most twenty three year of age. There is no minimum age requirement. It is held at the end of July or beginning of August. The IMC is primarily a competition for individuals, although most participating universities select and send one or more teams of students of approximately four student per team, plus one or more Team Leaders. Students coming on their own, or in a group without a Team Leader, are welcome and encouraged to participate.
