personally, i dont think that physics c is that hard. it was my first physics class in hs, so it was a little difficult at first, but i got used to it and i did well. the math doesnt get that bad, just pretty basic calculus, but it could depend on the teacher. as for hw, i dont get much. maybe 2-3 problems a night so about 30 minutes. its a fun class, but you would have to like physics and math a little to enjoy it.
