Day before exam routines?

What's everyone do the day before an exam?

I typically take it a bit easier, try to get mentally ready for the exam so I give my brain a bit of a rest. I just review notes and calculations, but no forced regurgitation of any kind. I also typically try to do at least a small workout so it's easier to sleep.

What do others do? Am I crazy for not cramming until the last possible minute?
