1. Don't try to stay awake by drinking coffee or smoking. Students may keep physically alert, but mentally numb.
2. When taking "a quick breath," don't light a cigarette. Get into fresh air and clear your head. TRY A CIGAR.
3. Don't study in a room that is too hot or too cold. If the room is too hot, you become sleepy. Those
who believe that the brain works better in cold temperature will probably miss exams because of colds or more serious ailments.
4. Don't study beyond 2 a.m. After that the outgo of knowledge may surpass the intake.
