Even skimming the subject matter for 5 minutes beforehand helps you get more out of the lecture, by preloading the basics (structure and terminology). I try to understand during the lecture (there's little to revise where I succeed). I can do this while taking notes. In the past, I'd take semantic notes, based on my understanding, flagging keys, as an aide de memoire to trigger my memory rather than be it. But now I try to follow the precise words, in case there's some nuance missing from my understanding.
