I used to do that but found keeping everything online much more effective. I do all my notes in Notion. It’s super easy to use once you get used to it. I also scan all the tests/handouts and keep them in folders on my laptop. I’m a bit of a messy person so i would regularly lose all of the papers. Now I have everything from DP1 nicely stored, if I need a physical copy I just print it out.
As for making notes, I figured a method that’s a bit time consuming but effective. I do some notes in class out of what the teachers say (either on my laptop or on paper doesn’t matter). Then when I have some free time I open Notion and use the syllabus, a textbook, class notes and sometimes other resources to create full notes. That way I revise all of the material after class and I have solid revision notes for before the exam.
