**Undergraduate Courses**

- Regularly Offered: courses required for the major and minor plus regularly offered electives

** For graduate courses we prefer a model in which the faculty have some flexibility in what topics to cover and how to cover them. This approach keeps the courses fresh, modern, and up-to-date. Therefore, the description of graduate courses are in several forms. Each description should be viewed as an *example* of how the course might be taught, not as a list of required topics taught in a specific order.
