Yes, make sure you get as much sleep as possible. In the morning prior to your test you might want to go over a logic game that you already know well... just to get the juices flowing. Get to the test center relatively early so you are not rushed (at least 40 minutes before). (Bring a silent timer if you don't already have one). Don't talk to other people about the test, especially during the break (unless you have friends there... but even then you might want to talk about other things).
Eat fish (brain food) the night before unless you are allergic etc.
Oatmeal or Total in the morning to keep you going.
Oh ya, bring plenty of pencils, erasers, pens. Not sure if you can use pens anymore, its been a while
Most Importantly, RELAX. You'll do fine.
