Dear jatin
Its good to know that you have finished your course and you want to revise it.
I would suggest you a very simple way.
You first note down the no. of chapters you have in each subject. After that just fix a time say 15 days to revise it. .
Divide the course equally among the 3 sections and divide the time you want to study each day as well among the 3 equally.  This way you will be able to revise it.
All the best. I hope this was helpful to you.
