Recreational Problem Sessions

Each fall, usually during the months of October and November, there is a weekly recreational Problem Solving Session.
This is intended to help students prepare for the Big E and Special K contests and for the Putnam competition.
At the sessions, students are given some mathematical problems to solve.

This year, due to Covid and the delay of the Putnam, the sessions will be held online in Winter 2021.
We will be using Piazza as our discussion forum. Here is the sign up link
