These AP tests, which are already probably one of the few objective competence-based exams, are going to be not trustworthy given all these issues. While probably not being grossly cheated on under this new format by huge numbers of students, it just is not believable that they're producing results fairly comparable with controlled testing environments.
Add to that the asinine notion to move everyone to Pass/Fail (or even "all-As", ala Berkeley) out of equity reasons, and this year is just an exercise in social promotion -- it's for sure not an exercise in effective education. I'm sure this will just add to the calls to toss out all tests (SAT, ACT, AP, etc), and just move to having your own teachers assess you on whether you're ready for college (no unintended consequences there, I'm sure!).
