Hi Ronak,
I hope you are doing good. Now coming to your query, Ronak reading hours differ from student to student because some students can easily grasp whereas for some it takes time. However, 6 hrs is more than sufficient for any students. But don't study only for the sake of marks in the exam because marks alone don't help you with your life. Along with the marks, You also need to gain subject theory knowledge and practical knowledge. Apart from academics, you should also be updated with technologies or discoveries in your field and it is also necessary to focus on your personality development.
I hope this helps.
All the best.
Thnk you.
