If you want credit in the physics courses that will actually save you time, then you do have to get a 5 on the AP Physics C exams. So…in your rather snippy comment, you displayed the relevance of the point being made by srparent.
You could get a 4 in AP Physics B and get credit for Physics 101 and 102, but this isn’t going to save you any time since engineering students and physics majors don’t take this physics sequence in the first place.
