The William Lowell Putnam Mathematical Competition , often abbreviated to Putnam Competition , is an annual mathematics competition for undergraduate college students enrolled at institutions of higher learning in the United States and Canada regardless of the students' nationalities. It is widely considered to be the most prestigious university-level mathematics competition in the world, and its difficulty is such that the median score is often zero out of despite being attempted by students specializing in mathematics. The competition was founded in by Elizabeth Lowell Putnam in memory of her husband William Lowell Putnam , who was an advocate of intercollegiate intellectual competition. The exam has been offered annually since and is administered by the Mathematical Association of America. The Putnam competition now takes place on the first Saturday in December, and consists of two three-hour sittings separated by a lunch break. The test is supervised by faculty members at the participating schools. Each test consists of twelve challenging problems.
