A prerequisite means a course or other requirement that a student must have taken prior to enrolling in a specific course or program.

A corequisite means a course or other requirement that a student must take at the same time as another course or requirement. Should a student withdraw from a course that is a corequisite to another course, they will be administratively withdrawn from the remaining corequisite course(s) with a grade of "W." Withdrawal from these courses may result in withdrawal from the University.
