Depressed and Hopeless

There's only three days left before my SAT II subject tests and I know almost nothing. I scored below average in two of the practice tests in Math IIc, can't ****ing understand most of the problems, and don't have a graphing calculator which the books makes out to be a life saver.

I hate studying, I hate cramming but I hate failing.

Guess when your on the side of the hill you'll only go in one direction, down.
