The U of I Undergraduate Math Contest is a locally organized contest, offered in the spring of each year. It is modeled after the Putnam Exam, a nationwide math contest for undergraduates that has been called the "world's toughest math test" and which takes place in December of each year. The U of I Undergraduate Math Contest, along with a similar contest in the fall, the U of I Mock Putnam Exam, is part of an extensive Putnam training program at the U of I, organized by Professors Jozsef Balog and A.J. Hildebrand.
