I'm also a not-taker (as opposed to a note-taker) and my entire school career consists of binder paper covered with doodles while I listen, with half-hearted notes taken when the teacher required it for some reason. This got me into some trouble once or twice when the teacher lectured a fact that was nowhere to be found in the textbook, but for the most part it was just one of multiple things that made me a poor fit for academia.

I do make use of mind-mapping now, though. It's handy for dissecting a big linear text into branches and partitions and not overlooking parts when I try to review.
