Judge your time well, or at least limit yourself to the same amount of questions in a small limit of time when you practice. This will give you extra time just in case you run into something on the exam that you can't solve and give you time to look over your problems. On second glace you can always find something else to change or re-solve just in case. Solve more problems on your own time then just in class.
I think I'll get a 5 or at least a high 4. (knock on wood of course)
