Hello dear student,

If you have studied the chapters thoroughly and you are confident enough that you can solve the questions of a particular chapter. then it will be better for you to solve previous year question papers directly and you can check by solving those question papers in which questions you are stuck and then you can pick the book and start over with that particular topic and after that you can try to solve questions from paper making that topic questions.that way you can stronger your concepts and you will get a feedback by your own where you are lagging.

I hope this helps

Thank you
