Passing the AP Physics C Tests usually gives credit at college for a similar class. However, I was wondering, if I'm majoring in Physics and did pass the AP Physics C Tests, should I skip the classes in college and move on? Or would it be better to take the classes at a college anyway in order to master it better and learn the things that my high school teachers left out? Is the AP test/class any real indicator of how well I know the subject(s)? Any thoughts/input on this subject would be appreciated.
