Dear [First],

To make registration as easy as possible, complete these tasks ahead of time:

Register for Classes

Register as soon as your enrollment time begins for the best chance to get the classes, class times and/or instruction modes you want. For step-by-step instructions, see our registration pages.

If a class you want is full, add yourself to the waitlist and set up drop if enrolled to automatically drop a backup class if you're enrolled from the waitlist.

If you’re planning to check your degree progress (audit) to prepare for registration, please note that the degree audit system will be unavailable beginning at 5 p.m. on Friday, Nov. 14 and through Sunday, Nov. 16. Learn more about the upcoming degree audit system upgrades. 

Coming Back After Some Time Away?

Even if you're not taking classes this fall, you're still considered an active student if you've been gone for fewer than two semesters plus summer (undergrads), or if you took an official leave of absence (grad students).

  • To take classes this spring, just follow the steps above to register.
  • If you've decided you need additional time off, see our withdrawal page for your next steps.

If you have questions about registration, feel free to chat, email, call or visit us.
