Schools will sometimes waitlist students requesting particular exams for various reasons. If you receive a message at the end of your registration that you are waitlisted, you will need to wait for the school to approve your request before you are actually registered for the exam. You will not receive a confirmation email or payment information until you have been approved from the wait list.
Students cannot register for the same exam at another school using Total Registration while they pending on the waitlist. If you wish to register at another school you will need to ask the school you are waitlisted at to deny your waitlist request.
