OwlLover, what can I do to help. I'm something of a math guru....Shall I make a cup of tea and help you through tonight? IF I were you, I'd grab a snack, and some tea or coffee. Work hard and as fast as you can, but take a snack break every hour, that'll help you hold out. All nighters suck, not passing would suck more. Hand in your work, and go home sick!
