Courses with numbers in the 5000 series are offered both as advanced undergraduate and beginning graduate courses. Graduate or undergraduate credit is awarded based on whether the student is admitted to the university as a graduate or undergraduate student. Any exceptions require the written approval of the appropriate graduate program director or academic dean; this approval must be presented by the student at the time of registration in order for the student to be registered for credit differing from admission status. Courses with numbers in the 6000 series or above are open to graduate students only.
