The list of courses offered under each program includes for each course the catalog number, title of course, credit in semester hours, class and laboratory hours per week and the description of the course. It is the responsibility of the student to check with his or her department for verification of the scheduled offerings. Graduate credit can be earned only for courses numbered 600 or above. Each 600-level course carries a 400-series undergraduate level course. The 400/600-series courses are taught concurrently in the same classroom setting. Courses numbered in the 300 and 400 sequence are primarily for advanced undergraduates but are offered also for graduate credit when they carry the corresponding 600-level number. Students who receive graduate credit in such courses must do extra work of an appropriate nature as determined by the department and are graded according to graduate standards. Courses numbered 700 or above are restricted to graduate students and certain qualified Clemson University seniors. The 700-level courses are designed primarily for the degrees that emphasize professional practice rather than research. A secondary listing of a course in parentheses implies that this course is cross-listed with another program.
