Lowest mark you've ever recieved for a final grade?

[EricW]

Errrm... There's this class that I'm taking and I've left all the studying until the last minute. I was sick for the mid term so the final is 70% of my total mark. The other 30% is from assignments but I didn't do those either.

Realistically, I can see myself getting maybe 25-30% for my final mark. This is not going to look good as my final is tomrorow.

What's the lowest final grade you've ever recieved?
