AP registration is a two step process:
Step 1: Please login to your College Board account and use your AP classroom's "Join Code" to gain access to your AP resources. If you plan on taking the exam, you must change the "Order Exam?" prompt from "undecided" to "yes".
Step 2: Payment is done through Total Registration and the link to pay will be live on August 12th - November 6th. No registrations after this time will be accepted. Please open the attached letter for more information. You can go to https://user.totalregistration.net/AP/030581 to register and pay for your exam today.
