What Waitlists Are
When a class is full, departments may offer a waitlist to allow non-enrolled students to get in line for the next available seat. When automatic waitlist enrollment is active, the first eligible student on the waitlist is automatically enrolled as soon as anyone drops the class.
When you're on a waitlist, you aren't enrolled in the class; however, you do appear on the class roster and you have access to the online class materials until the waitlist cancellation date.
Although a waitlisted class's credit hours are included in your credit-load limit, they don't count toward your academic or financial aid enrollment status or appear on your bill until you're enrolled.
