When you select a class you will see more information about the class, including prerequisites, corequisites, or other limitations on enrollment.
Additionally, you will be able to enter your Permission Nbr (Add Code) if you received one, or select agrading option: Graded = (A-F) or Pass/No-Pass (P/NP)
If you see the class has a waitlist icon, you must check the waitlist checkbox. Otherwise, if the class is open then just click on "Next"
Important: If you add a class that has a co-requisite, you must add BOTH classes in your shopping cart in order to register. Co-requisite courses are courses that require enrollment in the same semester. For example, Chemistry Lecture will have a required Chemistry Lab class.
