I get maximum 9 hrs from daily routines.so how can I spend this valuable time in last teached 45 chapters and running chapters

Hello dear student,

It's very Important for you to study in class when it's going on with all your concentration. So sad soon as you reach your place then revise whatever you have read in your class. Because by doing so you will be able to memorize that for a longer time and you don't have to put extra effort later to learn that again . So after this , you have to pick old chapters that's already been done in class . Revise them . Divide your chapters in 2 ways . Once that you remember less and you have to focus on them more. Another those you still remember and you can give them less time. I hope this was helpful and you understand this .

Best wishes
