THERE ARE LOTS OF QUESTION PATTERNS IN LOTS OF BOOKS,ITS DIFFECULT TO DO ALL QUESTIONS SO WHICH QUESTIONS SHOULD I PREPARE FOR IIT??SHOULD I FOLLOW ANY SPECIEAL BOOK??IF YES WHICH BOOK SHOULD I FOLLOW FOR ALL SUBJECTS????

Do not follow so many books. Each and every book is defined from the same concept of the lesson. You concentrate on only 1 book and do it perfectly. But remember NCERT is the main base for everything. so concentrate on NCERT.

Start practising and plz approve my answer if u like it.
