AP scores do not have to be reported if you did not do as well as you hoped. The tests are expensive and a lot of kids take the classes but not the tests. The tests that WP considers for admission are the SAT and/or ACT - not AP - AP tests factor into validating classes (skipping to next level) but validating can occur in their absence if you do well on subject validation test during BCT.
Forgot about that, my HS district paid for everyone's AP tests, so thats an additional factor I wasn't considering.
Very few AP tests affect validation, so their primary purpose, if not taken parallel to the class, would be for plans B through Z schools, for validation and admission perks.
Bulldog, that's not accurate. I'd stick to letting the people who have some experience with the validation process answer these types of questions
