<p>I’m asking because I am thinking about self-studying a science AP. So if I get like a 2 on the exam, I can just cancel the scores after seeing them, rite?? So there isn’t too much of a risk taking an AP exam after self-studying rite (except for the test fee)?? Also, I need to understand the difference btween grade cancelling and grade witholding. Can some1 explain to me under which circumstances would u use each AP exam service??</p>
