Thanks all!
How nasty - in my last (3rd) year of university, I land up with my last 2 exams both falling on the same day!

The first one went ok and I really should pass (honestly - I did put the effort in) and the second is a bit indecisive. I have had too much on my plate recently to really put the effort in, and therefore don't deserve to pass it. So I won't be too upset either way.

Really appreciate the thoughts everyone!
