Frankly speaking NCERT is not enough. It’s the basic and most important that one must read for NEET. Biology is full NCERT based but not Physics and a Chemistry. Now it’s time for revision only. So divide the days in 3 parts like morning , afternoon and night. Read each of three subjects in each phase and also practice questions. 

Make a time table covering each chapter everyday. On weekends, take mock tests and practice the mistakes.

Thanks for the question.

Only one month is left and you can now focus on practising sample papers and completing them within 180 minutes. 

Next what you should do is read NCERT biology again and again. Master the book so that the bulk subject  is best.

Practice numericals. 

Good luck 

Hello Prakash,
In order to score a good marks in the NEET 2019 examination, you should read NCERT books of Physics, Chemistry & Biology of class 11th & 12th at least 2 or 3 times for basics, your basics should be very clear upto class 12th. After that HC Verma for Physics (part -1&2), Biology by Trueman (volume-1&2) and Pradeep Guide on Biology, OP Tendon for Physical & Inorganic Chemistry, and Organic Chemistry of "Arihant Publication" for detail or extra knowledge. Your study materials provided in the coaching could also be helpful. You can also read more books whose names are given in the link given below

You should also try to solve the previous years question papers, this helps too much and you should also give the mock test to rectify yourself and build your confidence level.
For preparation of exam, the most important thing is your confidence after that you should know the whole syllabus and make your plan properly for learning new chapters, solving the numericals and revision. All three things should be the part of your preparation strategy in daily routine.
The main thing is that you have to build your concentration level, then only you can stay focused on your goal. I would like to say that please limit the study time between 10 to 12 hours and please increase your concentration and speed of reading, understanding and solving the problems then you will not face any kind of difficulty.
