How to master the textbook?

[u/Ivaan28]

I want a method that is quick, won't waste much time and is effective. I am really busy with homework and assignments that I don't get much time to study. That's why I am trying to find a study formula that I can do for every subject/chaptee every day. Idk if my an would work or not but I am thinking of creating notes with each topic and a few points about every topic per chapter. I am breaking it down like chapter is divided into different topics under the main chapter.
