AP = Advanced Placement? (I think I may have heard the term mentioned on the Couch before - I'm reading up on it now but I'm not quite sure I understand it. I just don't know enough about the US college/university system, not from the students' point of view anyway. I have colleagues who have lived and worked in the US and who have told me about the tenure system, but how undergraduate courses work is pretty much unknown to me. I have to look up "college credit" next... )
