Total Registration does not save the registration until everything is complete.  If your confirmation does not contain all the information, you never completed the registration, previewed you registration and confirmed your registration.  For some of the online processing options that schools have, the registration is not saved until payment has been sucessfully made or another form of payment is selected.

If your confirmation page is not complete, please log in at www.Student.TotalRegistration.net and click on Register for AP Exams.  If your school's registration window has closed, you will need to talk with your school as the registration end date is set by the school.
