About the competition

William Lowell Putnam, Image source: math.scu.edu/putnam/ The Putnam competition annualy takes place in December. From the description:
The Putnam examination tests originality, technical competence and familiarity with the formal theories embodied in undergraduate mathematics. Questions cut across the bounds of various disciplines, and include self-contained questions that do not fit into any of the usual categories. These self-contained questions can involve elementary concepts from group theory, set theory, graph theory, lattice theory, number theory or cardinal arithmetic.
