choose the key points that you need to focus on and keep track of them. details are also important, but don’t add too many unless they all relate to your key points. if you’re one to add color to make your notes more interesting, i suggest sticking to 1-2 colors.
I would recommend planning things out such as your note-taking. Like for example when I am doing my lessons I list them by their titles and make sure to write down important things like a procedure for solving math problems. Try to highlight some words while you're at it, you can also color-code them to help you out in the future!
