Course descriptions are listed alphabetically by subject prefix. Each course description begins with a three letter subject prefix followed by a three – digit course number and the course title. The number on the right of each course description gives the semester credit hours for that course. If a course includes laboratory or other special activities, that information is contained in the course description. Prerequisites are also listed. A prerequisite is a course, experience, or other required preparation that must be completed before the student is permitted to enroll in the course.
