New reg process & timing this year! AP Exam Registration is open now through Nov. 1. Beginning this year, students register in two places, on CollegeBoard.org (with a “Join Code” from AP Teacher) and on the Acalanes Web Store. Detailed information, including step by step instructions, is available on the Web Store and will be discussed in AP Classes. Please contact Hannah Welling, Testing Coordinator in the Counseling Office if you have questions or concerns.
