For the one year of college I did it, taking notes on a yellow note pass during class, then copying and cleaning those notes into a dedicated spiral for that class made a huge difference. Every test was easy and I was a superhero. Then I got into the social scene in a big way and the extra hour or two per day it required was too much! I still regret not keeping with it and think there is a way to incorporate it today but not entirely sure. I use one note a lot to keep electronic records of my meetings but there isn’t a way to analyze after the fact.
