PANIC!!!!

ARGHHH!!! I have an interview on Monday for a job that sounds great is close to home and has awesome benifits (one of which is Fridays off all summer, with pay. How kick ass is that?), and now the University I'm attending wants me to come in to do a civil service test tomorrow at 7:30 a.m. This would be so completely awesome because I would have fully paid tuition if I got it. I'm scared to death. I'm such a dweeb during interviews. I can never think of the correct thing to say, and end up coming off like I've been whacked in the head a couple of times. ARGHHH!!!! That and one of the tests is on budgeting. What??? Huh??? Please pray I don't make a complete ass of myself!!!!
