Automatic enrollment from a class waitlist ends the day before the semester begins. After that, a student on the waitlist is not moved into the class, even if a seat opens. To add a class once the semester has started, attend the first class meeting and ask the instructor for an add code. Instructors give codes only to students who attend, and only when a seat is available.

An add code must be entered in the online registration system by the end of the second week of the semester. Codes expire after that point, even if they were never used. Fees for an added class are due within five days of enrolling, or the student is dropped from the class. High school students taking college classes must also upload an approval form signed by their high school counselor before an add code will be accepted.
