Students who wish to enroll in a graduate or a 100- through 400-level undergraduate course without receiving credit may do so if they secure the advance approval of their advisers. At registration, indicate "not-for-credit" status by placing the symbol N in the appropriate column on the registration form. Students must pay the normal graduate tuition fee for the course and fulfill the same requirements during the term, including the execution of any written assignments, as all other students. Students must perform all the assigned work; however, they may not take the final examination. A grade of S (satisfactory) or U (unsatisfactory) is assigned. The course and the letter grade are included on each student`s record, but no credit toward a degree is given. See also Grades and Records later in this chapter for information regarding credit prefixes.
