# Math149S: Problem Solving Seminar

This is a resource page for undergraduate level math problem solving, especially those preparing for the Putnam math contest. Here are the lecture slides and problem sets from the Math problem solving class Math149S that I co-taught with Matt Rognlie in Fall 2009 at Duke University. The class met every Wednesday from 7:30pm to 9:00pm. Those who are interested to take the current version of this half-credit class should contact Dr. Kraines. Please cite this page if you use the slides.## Course Schedule
