Personally, i wouldn't do the CAT. Do some review 2 days prior, formulas, SC rules, and do some problems to exercise your brain. But don't do a CAT. Day before- don't do anything, just relax.

In my opinion, don't eat any new foods or combinations. If you have eaten this before, cool. But there are too many risks to screwing things up to throw a new food into your system the day before or of the test.

I completely agree with the above advice! Relax, review some easy concepts and go over relatively easy problems, and take the day off on Sunday to just unwind. Don't try to do a CAT or tackle harder problems, since it'll only stress you out if you find you didn't do as well as you thought you should.

On the day of the test, keep your normal routine. If you usually eat a huge breakfast, then eat a huge breakfast. If you normally stay away from coffee, don't try it out the day of. Bananas do sound great for a snack though!

Good luck!

I guess I'm not worried about "cramming" since I'm a college student, so I'm used to prepping well into the night the day before my exam. I also do better if I keep things fresh in my mind, so I'll probably do the CAT but maybe just beef up on some easy problems Sunday for an hour and relax the rest of the day. The test isn't until 4 on Monday afternoon so I'll be pretty relaxed (or as relaxed as I can be before the GMAT!)

I have also seen around here that some people say it's a good idea to do 5 or 6 easy problems of each type on test day to get your juices flowing. Do you guys agree?

And yes, I'm used to bananas and chocolate.

I agree with not doing CAT before test. You do not run marathon a day before marathon.

Thanks guys. I tempered your advice and did a GMATPrep test without the AWA (I'm not worried about anything in the AWA section) because I wasn't comfortable going in not having done a GMATPrep at all.

I scored a 770 (48Q, 51V)! Goodness gracious. While I know this is skewed higher than it would be if I had never taken the GMATPrep tests before (I took them almost 5 months ago), the only thing I recognized was one RC passage and I didn't remember the answers to the questions so I answered them as if I had never seen them before. I'm sure there was some unconscious recognition going but I definitely did not look at any question and think "Oh, I remember that question, it's D." I'm sure it's also skewed higher than it should be since I didn't do the AWA but that was hugely encouraging!

I'm starting to get nervous for the test, but I'm glad this gave me a nice boost of confidence.
