The Putnam Archive

The William Lowell Putnam Mathematics Competition is a North American math contest for college students, organized by the Mathematical Association of America (MAA). Each year on the first Saturday in December, several thousand US and Canadian students spend 6 hours (in two sittings) trying to solve 12 problems. Individual and team winners (and their schools, in the latter case) get some money and a few minutes of fame.

This web site contains problem statements, solutions, and competition results for recent years.

Some additional resources concerning the Putnam competition include the following.

This page is maintained by Kiran Kedlaya; contact me with corrections and other comments about this material only. I cannot provide individual scores (see your school's Putnam coordinator) or assist with exam administration (see the MAA's Putnam home page for instructions).

Results from the 2017 competition, held December 2, were posted on February 20. My understanding is that this timing, which is 4-6 weeks earlier than in previous years, is likely to continue in the future.
