Enrollment changes are made in CalCentral.
You will not be dropped from a class for non-attendance therefore you could receive a failing grade if you do not attend. With a few exceptions, the only automatic enrollment transaction is a move from waitlist status to enrolled status. We expect students to drop courses they do not wish to attend. If you are not attending a class, you need to submit a "Drop" request through CalCentral. If you did not get added to a class for which you were waitlisted, you will need to submit a "Drop" request. Please read the section on Refunds to be sure you understand the financial consequences of your adds, drops and cancellation/withdrawal.
We strongly encourage you to speak with an adviser in the Berkeley Summer Sessions Office before adding or dropping a course.
