Aplogises for spamming,unforuntaely i pressed the enter button. So for giving NEET one must know three subjects PCB. NEET comprises of 540 marks and different category has different cutoff and sectional cut off as well. NCERT is the basic book and should never be ignored. For chemistry it is the bible. For P and B one must go through notes and practise as much questions as one can. hope this answers your query,cheers!

Thank you sir...the question pattern remains same in ISC and CBSE board? 

No, there is a difference.
