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. On occasion, an upper level student may be given priority as long as it does not hinder the progress of another student.
