Before you can register for fall or spring classes, you need to complete preregistration for that semester.
Once a semester's classes are posted in CU Boulder Class Search, you can complete your preregistration items through the student portal.
- Log in to the student portal.
- Click the Student tab.
- Click Register for Classes.
- If prompted, select the term you're enrolling in, then click Continue.
You should now be on the first preregistration page.
