I don't take notes, but use a pen and paper as a scratch pad. If the paper has some math, I can sketch it out and try to break it down, allowing me to understand it better. Or if there's a weird concept, I can draw it out and visualize the issue. It's also useful when the information is really dense and there are certain things I need to go back and recall but don't want to search my short term memory for.
