## Courses

» Please see the Schedule of Classes for the current semester’s offerings.

Except as noted, all courses are 3 credits. Except in the case of Topics Courses and Problem Seminars, the first semester of any two-semester course will include a survey of the important topics in the course. The second semester, which will be given only upon sufficient student demand, will consist of a deeper treatment of certain topics covered in the first semester.
