Day Before the LSAT

1. Take it easy. Plan to do something fun, and don't plan on studying. If you like studying, it won't hurt. But don't feel the need to do so. You're prepared. Now is the time to relax and to get rested for the day ahead. That said, don't get all worried about getting enough sleep; you'll get through the test. Just say no to partying and you'll be good.
2. Figure out how to get to the testing center. And, if possible, go to the testing center. That will ensure you know how to get there, how long it takes, and where to park. Once you're there, if you can get in the building, check out where you'll be sitting, the clock (if any), restrooms, drinking fountains, and so on. The more you know, the more relaxed you'll be.
3. Print out your ticket even if you already have. Make sure your testing center hasn't changed; it's happened before.
4. Pack your zip-lock bag, which must be one gallon (3.79 liter) or smaller. Contents.
5. Set your alarm and go have fun. You've done all you can do.
