if the notes were for an English class or writing class, take notes on some of the more important things/concepts. if its a science/math class, you should take notes on all equations and concepts and what they mean. Note taking also varies depending on what grade-level you are in. if in college you will take a lot of notes but also likely find resources from your professor online and also will likely find other things outside of class for your own notes. if in high school and below, you will likely only take notes in-class and just from your homework.
