Stages to divide material to study

Good morning! I would like to know if someone has an idea of how to divide the course notes/ text book chapters into stages in order to have a better control of the progress of the material covered. I would like to avoid struggling or spending too much time in some chapters, leaving for the rest not enough time. I have already make a try for the paper one year ago but it seems that I’m not the best manager of resources in order to approve paper F5. I would appreciate any advice regarding this matter.
