Need advice...fast

Ok, for one of my courses, I got really well on the midterm and kinda stopped going to class after that My fault and I'm not going to argue, I did a really stupid mistake. Well I have my final exam this friday (from this moment it will in in exactly 36hrs). It is humanely impossible for me to sit down for 20hrs and study so it will be pointless to suggest that, but I do have to things to my aid
1.) I am allowed a double sided 8.5 x 11 cheat sheet
2.) I have access to previous years' finals.

This is the course outline...

Now some of you who have gone through computer science might know a thing or two about this, what's my best course of action right now?
I'm not asking for a miracle of any kind, and right now I have something like 88% in the course more of less, but we HAVE to get 50% or above to get a credit. I have defianetly learned from my mistakes and am going to go to class from now on. Ijust don't want this to cost me. I was thinking I should look at the the previous exams and find the repeating questions, learn them, put them on the cheat sheet, and try to learn the rest. Anyone else have any ingenious ideas? HELP!
