The William Lowell Putnam Mathematical Competition

Scope

Undergraduate mathematics; demanding, clever and non-typical problems intended to challenge even excellent students.

Rules

The competition is open only to regularly enrolled undergraduates, in colleges and universities of the United States and Canada, who have not yet received a college degree. No individual may participate in the competition more than four times. An eligible entrant who is also a high school student must be informed of this four time limit. A college or university with at least three registered entrants obtains a team rank through the positions achieved by three designated individual contestants. No collaboration or outside assistance is permitted during the examination. Each contestant, even if designated as a team member, must work independently on the examination questions. Please note that there are no provisions for “unofficial’ entrants. The local supervisor must be a regular faculty member.
