my personal notetaking decreased as I went through the first two years. We have a notetaking service, and we quickly learned who did good notes and who did poor notes. So, when I knew who was doing the notes, that might influence my decision on how much personal notetaking to do. I took all my own notes for gross anatomy, as they were often based on diagrams the instructor drew or passed out. '
I also was one of the people that other students would pay to do notes for them, so I did take lots of notes that went into the notes system. During the second year, mostly I followed along with the handouts and the prior year's notes (big sib system like the previous poster) and jotted down a few things.
Very few people can keep up with the pace of notes for a long time in med school. I think most schools have some sort of notes system, along with handouts, that keep your frantic scribbling to a minimum. But definitely try to jot down a few things, at least, as it keeps you more actively involved in the lecture. Or, better yet, practice selective skipping. IN retrospect, I wish I had gone to class less and spent that time memorizing the triva (I'm not a good memorizer)that appeared on our exams.
