Do you do anything differently? Wake up earlier/stay up later than usual to study? Do you eat differently?

Personally, I go through my notes for the first time (if I hate to) for the semester. I read my notes, book chapters and such probably twice, more if I feel I am not ready for an exam.

I also try and stay away from going out and hanging with friends which is obviously a distraction.

Please share your current or even past "exam-lifestyle".
