What is the probability that the college board incidentally replaced your AP score with another student’s or improperly scored the multiple choice section of the exam?
Nearly impossible, unless there was a mistake on the form, in which case that would be your fault.
If you got a bad AP score, then it sucks, but it’s not going to get changed.
Pretty close to zero. You can pay for a rescore, but in my experience, the score will not change.
