I missed March 13th 2026 Deadline to register my son for AP BC Calc Exam

Hello,
My student is enrolled UC Scout for AP BC. But he did not know that he has to enroll himself for AP Exam.

Internet search revealed the March 13th which was yesterday was the last day to enroll. He is a good student and he hard work should not go waste. Not sure what should I do. Please advise.
Thanks
Thanks
