For me I always wrote as i listened, still do often. I rarely read the notes back.

'Revision' was just writing a whole new set of notes either from memory or from sources. Then, never reading that set of notes.

Massive waste of paper and ink, but it's part of how i pay attention. Most of my lecturers did provide printouts of all the slides, but I'd scribble all over them anyway.

Typing doesn't do the same thing at all for me.
