The College of Liberal Arts and Sciences may provide permission to a student or may add a student to a class with student and instructor permission through Census, provided the room has capacity for that student and all prerequisites have been met, or explicit exception to a prerequisite has been granted and no other circumstances are preventing the student from being eligible, i.e. course overload, time conflict or holds that prevent normal addition of a class and require additional approvals. After Census, a student must petition and obtain permission from the appropriate assistant/associate dean for this to occur, according to deadlines posted in the academic calendar.
