<p>for FinalCut - Oxbridge at least don’t really care about the vagaries of different school systems in the US. If you don’t have the APs they’re looking for in your subject, and won’t be taking them senior year, you won’t get it. Sorry, sounds harsh, but you can always self-study which I know would be difficult for say BC calc or Physics C, but it’s doable for some arts subjects.
They’re going to want 3-4 AP exams that directly relate to your intended course, whether you apply with those scores in hand or plan on taking them sr year (in which case you might get a conditional offer)</p>
