When I was in college I asked my math professor who taught previously at Duke University before teaching at the small Georgia College I attended, "What is the difference between a the students at Duke and the students here at this college?"
If you would, take a moment before reading ahead to think to your self what the difference is a small Georgia college and Duke University would be. ... Okay, now back to the story.
As I waited for his reply to my question, my mind started racing with possible answers such as the students had higher SAT scores, better study habits, are good at school, had really smart parents, and so on. But these are not even close to his answers because it was simple. First he said the student read the math section before coming to class (just read the section, they did not solve the problems). And second he said that they students would re-write their notes after class.
How difficult would this really be to do? To spend 10 minutes to read a math section and then about 10-15 minutes at home to re-write (re-organize neatly) the notes from class?
Wow!! You can make better grades and be more successful by using these two approaches.
