Hello Arbaz

Dear there is abundant study material available for preparation for the entrance exam. However, students often struggle to find out the right material for preparation but some end up following the wrong ones and then face result issues. There are many good reference books but it's not possible to study or refer them all. So, one should identify the right and result oriented material for competitive levels. NCERTs are highly important especially for NEET to understand the basics, the theories and concept clearing. 70% to 75% questions comes from NCERT books. 

Once you are thorough with the NCERTs then you can refer the following reference books for practicing levelled questions for the entrance:

Physics: DC Pandey, Universal Selfscorer- Errorless, HC Verma (this book is the most referred one- for understanding the basics + NEET level questions)

Chemistry: OP Tandon, Objective Chemistry by Arihant Publications

Biology: NCERT is more than enough for preparing biology for the entrance. As maximum number of questions are asked from NCERT itself. For detailed study + question practice- refer Truemans Biology volume 1-2, Objective Biology by Dinesh.

Undoubtedly, NCERT books give an excellent head stays for NEET as majority part is covered from it. Try to be thorough with the NCERTs first for all 3- PCB and practice questions- solve previous years question papers for better idea of question-pattern-level. Hope you're getting my point.! Prepare well and study smart.! Practice maximum to score maximum..

Hope this helps.! Good Luck.!
