I mean when you get accepted as a Freshman in college, they may tell you that you can't or shouldn''t use the credit you got from passing the AP exam and retake the Physics course as a freshman instead, depending on what you are going to major in.

Also, when my son took (either physics or engineering) once he was a Freshman in college, it was the same situation again. The whole class was practically failing the tests and the professor curved the grade. My son was freaked out that he was failing and ended up with an A.
