I am a 3rd year undergrad, and I still haven't mastered the very technical art of note taking. I attend all my lectures, like I haven't missed any! However, I often find I will miss a bit of information, so I rewatch the entire lecture recording, and make more in depth notes then, so I never look at the notes I took in my live lecture again! I'm know I am wasting valuable time doing this, but I don't want to not attend lectures. What are other people's methods, to take valuable notes in lectures, including any preparation work I may need to do?
