What are some strategies that you take to prevent you from sleeping while studying late at night?
here are some of mine:
Always read at a table. This will prevent you from falling asleep. Use a hard chair to also help keep you awake. Futhermore, the table allows you to have a platform that will support your book and make reading easier.
when you realize that your mind is slugging and you're not understanding what you're studying, go wash your face with cold water. go outside and do a few jumping jacks or something to get your body active. do some pushups or pullups.
take a 20 minute short nap. these are supposed to be very effective in helping you regain your strength. if you think u'll fall asleep until the morning, then take a nap in a chair instead.
