Set Up Drop If Enrolled

What It Is

If you're a full-time student and you're on a waitlist for a closed class, it's a good idea to enroll in a backup class to ensure you have a full schedule if you don't get into your waitlisted class. If you've set up drop if enrolled and you're enrolled from the waitlist, the system will automatically drop your backup class. (Â鶹ÒùÔº will only be automatically enrolled from the waitlist or have drop if enrolled applied through the add deadline for the semester or session.)
