What you need to know

When registration opens, meet with your advisor to finalize your academic plans for the term. Your registration is populated with your pre-registration selections, but it is not complete until your advisor or registration officer has given approval and you have submitted your selections online.

Some key points to remember:

  • Before you submit your registration, you must clear any registration holds connected to outstanding obligations from prior terms.
  • If you did not pre-register for a CI-H/HW subject, you will only be able to add yourself to waitlists for those subjects during registration.
  • Undergraduates — if you are registered for fewer than 36 units, you are considered to be less than full-time. Learn how registration load can affect you.
  • You must acknowledge terms and conditions before submitting your registration.
  • Registrations submitted after the first week of term are subject to a $50 late fee, and failure to complete your registration by the end of the second week will result in the loss of student status.
  • A petition ($100 late fee) is required to complete registration after the final deadline. Undergraduates — petition the Committee on Academic Performance. Graduate students — petition the Office of Graduate Education.
