主要原因是AP考试越来越商业化，尤其是2015年开始，AP考生随时随地可取消AP成绩(Scores may be canceled at any time.)，该政策饱受争议。许多大学认为，即便学生非常优秀，也反感学生反复刷分而取得高的AP分数：
The AP Program allows you to cancel your AP Exam scores. When you request cancellation, your exam won't be scored, and if it has already been scored, the score will bepermanently deleted from our records. Once a score is canceled, it can't bereinstated. There's no fee for this service, but your exam fee is not refunded. Archived scores cannot be canceled.
Scorescan be canceled at any time, but for scores not to be sent to the collegeindicated on your AP answer sheet, AP Services must receive your request by June 15 of the year you took the AP Exam.
