After 2 years in college I stopped taking notes and just started listening. My GPA went from Deans list to "average," but my learning increased exponentially (ever notice how science types like an excuse to use that work?). I did horrible in classes that were only about memorizing facts, like sociology, even though, I have learned now, that that was a horrible way to approach such an awesome topic.
However, I did excel in classes where I had an "endeavor to conquer the subject matter." Most notably, I ended up working way ahead of my CS degree without realizing it. I was just following a path of reading material with just a few conversations with good professors.
In the end, I learned how to learn. I don't really remember much of anything from any of my coursework (4 years out now). But I know how to learn it again if I need to, and more importantly, there is no topic that I fear approaching for the first time or repeatedly.
