Might be a little late for this advice, but here's what I did. My last semester of college, I took Becker and treated it like any other class. Showed up for every class, listened and studied hard. I also worked as a tutor for lower-level accounting courses at school, which gave me additional review on some of the accounting coursework I hadn't seen for a while. I took it the first week of November 1986, and I remember I gave up going to a couple of Halloween parties and a concert to study, but it was worth it, because I passed all four parts on the first try.
So study hard, but don't get too stressed about it, either. I remember, we used to refer to it as "the quiz"

in order to keep stress levels lower.
I think Newt tells you all this, but get a good nights sleep the night before. If you don't know the stuff by then, a couple extra hours of cramming is not going to help, it's only going to make you tired and less able to concentrate the next day. Eat a good breakfast. Bring along an apple or something if they let you. If you're stuck on something or feeling too overwhelmed, get up and take a break, it'll help to clear your head.
One thing I disagreed with Newt on, was sitting near your friends. He said not to, but I had a couple friends close by and I'll tell you it was a huge morale booster to look up and get a little smile or a shrug from one of them when we were stuck on something. They may assign seats now, though, so that might not be possible.
Good luck!
