I agree with this, except for 2. I need to write things to internalize them, and I get a lot more out of lectures I take notes in because it keeps me focused.
I used to feel like this. Then (on advice of my high school history teacher) I stopped, and very quickly found I can keep my focus (and focus better) when I am not taking notes. Some people find that doodling helps. Personally, I find that I need an open notebook and a pencil in my hand, or I get really insecure and distracted.
This. By not worrying about whether your notes are actually complete / sensible, you get the cognitive advantages of writing stuff down without the distraction. You can still make a proper summary after class if need be.
I'm the same way. I remember things a lot better when I've written them down and also find my attention doesn't stray as much when I am writing things down.
