nervous

my first biochem test is tomorrow. i've been studying and memorizing and trying to understand the concepts, but it's so much information. i really don't know if i can get everything i need to into my brain by tomorrow. i think i'm most nervouse because it is biochem and the first time and last time i took biochem, it was a complete and total disaster (although, i will admit that it was still better than organic chemistry). well, i have to get a B or better no matter what, so there's really no use in complaining. *sigh* back to work...
