I am just a high school student but I am highly interested in human biology and medicine. my learning is mostly out of syllabus which I learn curiosity driven and what i learn mostly curiousity driven is like asking doubts, asking application based doubts and by that I learn something.but I cannot seem to take notes of what I learn properly.of course I can remember many thing, many names of systems and complex terminologies but it is just that i forget one or two things. so I need to take efficient notes right now. I don't know how to take proper notes so please give me some suggestions
