"... Printed in large, friendly letters, the words 'DON'T PANIC'."

There's only one day of class left for me.

You and I both know what comes next.

..... FINALS! *dun dun duuuuun*

I can see you freaking out at the mere mention of the word, oh yes. You're terrified that you're going to fail. You're wondering how I can be so calm about it.
I'll tell you how I can be so calm about it: I know that flipping out will do me no good. Running around like a headless chicken only brings your grades down. Same with trying to cram. Really, the best thing you can do before finals or any large test is ...

1. DON'T PANIC. No, really, don't panic.

2. Get lots of sleep and eat well.

3. Study in a quiet place where you can concentrate without being distracted.

4. Study in 1 - 3 hour chunks. After each, take a break for 15 - 30 minutes. Go get some fresh air, stretch, or eat. You could even take a nap if you need to.

5. Study for 10 - 15 minutes right before the test. Just review the information quickly. This will ensure that it's fresh in your mind and you'll be able to remember it better.
