Suggested program plan

The CBE curriculum is designed so that the courses from one semester serve as the foundation for those taken in subsequent semesters. This relationship among courses is expressed in the course catalog as lists of prerequisites courses.

Understanding the importance of these prerequisites is important for planning which courses will be taken when, especially when one considers that CBE courses are offered only once per year (i.e., either in the fall or the spring semester).

Of particular importance in the first two years of the CBE program are the requirements for math (MATH) and physics (PH) courses.
