The course number indicates the level of the course, with the exception of the first-year seminars, all of which are open only to first-year students and considered to be at the 100 level.

100 – 199 – Generally courses numbered 100 to 199 are introductory and open to first-year students. They do not have prerequisites.
200 – 299 – Courses numbered 200-299 are designed primarily for sophomores, juniors, and seniors, though many are also open to first-year students. If they are open to first-year students they should be so designated in the course description in the Catalog. Contact the Registrar’s office to update a course.
300 – 399 – Courses numbered 300-399 are designed for juniors and seniors.
