I'm dyslexic, lecturers talk to fast for me to notetske anything other than utter scribbles in the margins. That's why I like have the slides in advance I can add to them as I listen. Actively listening is how I do most of my learning, I didnt really reread notes (much) or do any extra study before exams. (Again, dyslexia put me off reading (for a long time) although I did manage to read some textbooks ok but it took a lot)
