My wife’s grad program in bio was basically a full-time job. They payed her, though. I don’t think she could have made it doing an extra job on top of that.

I’m not sure what your math questions are, but they might be answerable by WolframAlpha. it will sometimes even give you how a solution is worked out (if you pay, it will always do that).
