Students who audit a course may attend classes, take part in class discussion and activities and take quizzes and examinations on a voluntary basis. An "AU" grade will be entered on the student’s transcript, with no credit given. Students may audit courses after registration by registering and paying tuition for the course. An audited course cannot be changed to a credited course without the approval of the instructor. Schedule changes to audit a course cannot be made after the sixth week of instruction.
