Not good!?!?!?

awww man....I gots a final tomorrow and all i can do is try to cram every thing into my mind(relatively small thnxs to all the video games i play) and it is so frustrating for me. I got my own life to live I can't just stay at the school all day now that is a waste of time, very valuable time and time is money.....Why is that you ask, well it's b/c my grandmother is the only one who is paying for the bills and all and i feel sorry for her, and I really mean this.
