The Putnam Mathematics Competition
The William Lowell Putnam Mathematics Competition
is held at universities accross North-America
on the first Saturday in December of each year.
The contest is written, by undergraduate students, in two 3-hour sessions.
In each session, students are given 6 problems to work on.
These problems are quite difficult, and most students are
not able to solve more than one or two in the allotted time.
Prizes are awarded to the top 25 students.
