If a test taker registers for the wrong exam, can it be changed?

If a test taker registers for the wrong exam, they must log in to the My CLEP student portal, cancel the incorrect exam title, and then reregister for the correct exam. They must also print an updated registration ticket. 

To cancel an exam, go to the Exam Card on the "Upcoming Exams" tab and then click on the arrow to view registration details. Next to Exam Details, click on the link to cancel your registration.
