Its finals time and I can't concentrate at all. Before I was trying to find something for my sister, or email, or a handful of other things so I pulled myself away and lay down to study. That didn't turn out very well, or so the large wet drool spot on my papers told me(Slept for about 1 hour) so I moved to a chair and slept for 1.5 hours.

What do you guys do to help concentrate?
