Any course numbered 500 or above is designed for graduate students and normally carries credit toward one of the graduate degrees. Certain advanced undergraduate courses numbered in the 300s and 400s also may be approved for a given graduate student, either as a regular part of his or her graduate program or as a means of remedying a deficiency in preparation. When a matriculated graduate student is permitted or requested to enroll in a course numbered below 500, explicit approval by the student`s adviser is required and the credit prefix G, N, or E must appear on the transcript. The definitions for these credit prefixes are listed in the section entitled Grades and Records later in this chapter.
