I have AP credit for calc I and II and also for physics I. When I was getting ready to apply, I called every school I thought I might be interested in (I spent a LONG day on the phone
) to ask whether or not AP credit would be accepted. Most of the people I talked to had an answer for me...I got the impression that it is a common question. Most of the schools said it was fine, as long as the class I received credit for was listed on my transcript. However, I was also told by several schools, very nicely, that no AP credit at all would be accepted for pre-reqs. I wrote them all down, so here's a list as of last June :
Does not accept any AP:Boston University, Columbia, SLU, Yale
AP is fine:Cornell, Dartmouth, Duke, GW, JHU, Colorado, Northwestern, UPenn, Rochester, Stanford, Tulane, Wash U
This is just what I was told over the phone, so the list is not definite by any means! I have been accepted without taking any AP credit over again. Hope this helps!
