AP credits later on...

I was wondering about AP credits…
If I were to get a 3 on an AP exam and went to a college that gave me (idk 5 credits) many credits because of the AP score…
Would I still keep these credits if I were to transfer to a different college later on which required a higher AP score (like a 4)?

Or would I have to go back and do the classes for the credits?

If the college requires a higher score, it is unlikely that they will accept the transfer credit, but this really depends upon the college in question.

Your transcript from the old school would indicate which credit hours came from AP exams, so the new school would ask you to send those AP scores from the College Board.
