If I have an AP credit for biology, which counts as the first class in the two-semester "general bio" sequence at my school, will the second class in that sequence plus another advanced bio class fill the "Year of bio" requirement at most schools? Or do I need to take both general bio classes? Is there any reason not to take them both in the same semester? (I'm graduating next semester -- if I take, say, bio I and chem I I'll have to finish those classes at another school.)
