military graduate question

I'm working on my Masters degree and only get 1100 a month from the 9/11 gi bill bah. I'm looking for more free money to help pay for books and other bills. 1 class books cost 200$, far more then what the gi bill pays for. I'm plaing on taking 3 or 4 classes this semester if I could afford it. I'm taking 1 class on campus to get the full bah, and for 1 class parking it cost 120$ for the semester.
