I did something a bit different- at the end of the term, I would rewrite my notes. A v2.0 of them. In the process I was going over all of my previous notes, but by that point I had a much greater understanding of how all the things fit together, which details were important, etc... and my new set of notes, which were also not written under duress of trying to keep up with the teacher, were much better written.

The second set was always much cleaner, much better organized, and much more deeply ingrained in my brain.

As an aside, when I went to college, my first semester Computer Science teacher was vehemently anti-notetaking in class. He would chastise people who were taking notes either on their laptops, or in notebooks, saying "The slides will be online!" I really struggled that first semester, and found it hard to pay attention, hard to retain the information, hard to even understand what he was talking about, and it took me awhile to realize just how powerful the act of taking notes was.
