Dear aspirant;

NEET exam is only 4 months away now and for preparing in the best possible way you should cover your NCERT biology properly at first. You can solve your questions from trueman biology vol. 1 and 2 . This will help you a lot.

Now for chemistry inorganic NCERT is enough. Physical chemistry by op Tandon and organic chemistry from Ms Chauhan is preferable.

Physics is most important to crack NEET. For that you should have grip over the theory concept and keep solving as many problems as possible. That will help a lot.

Hope this helps and all the best!
