On holiday... free to do homework for you. Math, English, Chinese, Biology and Chemistry.
I'm really bored, on holiday right now. Throw me your high school or uni first year problems! Heck, even if you have questions tougher than those, let me try them out too.
I can do up to single variable calculus with confidence... A little shaky on linear algebra, multivar calculus and its theorems but I can try too.
Took AP Biology, AP Chem, AP Physics, AP Stats and AP Calc last year (I'm not from the US so I don't have to take everything).
Generally I can do physics too but am not as good at it as at the other subjects.
