In high school, I barely studied. It usually consisted of cramming the night before and that morning to remember specific terms and their spelling and such (terms in biology, or dates in social studies, etc...). I am a big procrastinator and love to cram. From my own experience the best way to study is to explain it to someone else. In high school, I always had friends or classmates asking me to either explain something or review a topic. I found that in doing so it helped me remember the subject better and be more familiar with it.

In university, I tend to have the same study habits minus people asking for help. That resulted in average marks. I am trying to do more work so that I can bring up my GPA. So I want to try to do about an hour but at the moment I am doing less.

EDIT: Chemical scares me. She is a studying fiend.
