Due to space limitations or pedagogical principle, all courses have a maximum number of students that can be enrolled. Once the maximum enrollment has been reached during the pre-registration period, students can be placed on a waiting list. As students with seats reserved in a course drop or withdraw, students on the waiting list will be moved into those empty seats on a first-come-first-served basis. Students who are still on a waiting list for a class when the term begins should meet immediately with their advisor to reconsider their course schedule.
