Some course sections will be offering a waitlist that students can sign up for via AppalNet once the section is closed. The purpose of waitlisting is to allow students the ability to more easily monitor courses they need that are closed as opposed to frequently checking back on AppalNet. Waitlisting will not be available for every course and being on a waitlist for a section does not guarantee the student will get a seat in that course.
