Putnam Exam

The William Lowell Putnam Exam is the premier undergraduate Mathematics competition in the US and Canada.  It is given annually on the first Saturday in December and consists of 6 problems in each of two 3-hour sessions.  The problems are always challenging, and a score of one correct problem usually places a student in the top quartile.

I will be running Putnam problem solving sessions for ISU undergraduate students on Fridays at 1pm beginning September 6.  Typically we will talk about problems from the previous week, discuss a new idea or problem strategy, and hand out problems for the following week.  The hope is that students might solve a couple and be willing to present solutions a week later.
