Hi there!

To keep on learning and retaining things constantly, one needs to study efficiently for however long duration one can sit in one go. Also, one must do a quick recap of all the things studied before starting a new topic. This helps us in maintaining the continuity and better understanding of the concepts. Once a chapter is done, make sure to revisit the short notes of the chapter in an interval of every 3 days. Once you are well-familiar with the chapter, now you can visit the chapter once in every 5-6 days. Hope this helps!

Thanks
