Students with little or no background in the social sciences should usually start with one of the 100-level Introductory courses. 200-level courses deal with topical materials at a sophomore level of difficulty, and are designed both for non-majors and majors with little or no background on the subject. 300-level courses are designed to meet the Political Science major requirements, but are open to non-majors and are not beyond the grasp of any dedicated undergraduate. They are offered only in the day, except as otherwise noted.
