Ummm....you can get off of myLot for starters

Usually a quiet environment works best, albeit extremely boring sometimes. If you are like me, (which I have to have something going on in the background) then playing some soft music in the background as a sort of “atmosphere noise” can also work - as long as it is soft, and not to the point where you are singing along instead of focusing. Also, it is said that it is better to study like a half an hour to a hour before you sleep, as once you study and immediately fall asleep, that will be the last thing on your mind, and therefore you will better be able to retain it the next day. Works for me, hope it does for you. Good luck.

just relax
