Pre-requisites consist of course, courses, or competencies a student must have before being allowed to register for a more advanced course in the same or related subject area. Co-requisites are courses that a student is required to take while enrolled or prior to enrollment in another related course. If a course description does not list a specific requirement, the successful demonstration of proficiency in basic academic skills is understood.
Not all courses are offered each semester. A schedule of course offerings is published for each semester.
