Actually, it's the reverse. If you score well on AP and then elect to take the class, you'll probably get a high grade. However, if you take the class and realize you're in over your head, you damaged your GPA. AP credits didn't count at my school for your final GPA, so fewer classes meant each class counted more. I skipped almost 30 hours of credit with AP. It still took me 5 years to graduate after switching my major 2nd year. If I had to re-take those classes I skipped, I would be 1) bored, and 2) loaded with busy work instead of being able to take classes I wanted. I have friends that had to take Calc 1, whereas I went right to calc 2. Can't say I would have wanted to take it again.
