Right. Reed (why are we fixated on them?) says bio, chem or physics, but there is variety and these are not high school classes. They also offer credit for scores of 4 and 5 on the biology and environmental science exams.
But OP asked about history. Over time, lots of kids like something about their hs classes and ask about a history major. And so often, can’t describe what in history it is. Or why. Give OP a chance to answer, before we tell him what education format he wants.
