Preparation for NEET involves a lot of aspects: - BOOKS: Please follow the link https://www.careers360.com/question-to-score-top-ranks-in-neet-which-book-should-be-preffered?icn=question-title-details&ici=topic-detail-page - PAPERS: When you practice these papers, solve them in a mock exam format and analyse your papers after that, outlining strengths and weaknesses. These questions are seldom repeated, their main purpose is to develop time management skills. Here are some links: https://www.entrancecorner.com/medical/articles/neet-2018-sample-papers/ http://www.careerpoint.ac.in/free-sample-paper/neet-sample-papers-download.aspx https://medicine.careers360.com/articles/neet-sample-paper - STUDY MANAGEMENT: 1) Skills: Everybody shows a diversity of study skills and tactics. To know how you learn best, check out this site, http://vark-learn.com/ It contains a questionnaire that will tell you your learning preference and various strategies to strengthen it further. 2) Habits: You need to figure out which duration of the day you attain your peak concentration levels and do the most difficult topics during that time. Study the other topics during other timings. Also, figure out which place is most ideal for you, clear of things you find distracting. 3) Planning: The old saying, "If you are failing to plan, then you're planning to fail" applies here as well. It saves a lot of time as you have an agenda of what you want to accomplish. Don't be disheartened if you are not able to complete one of the goals, no plan can be 100% perfect. I recommend, not to make rigid plans, keep it flexible - MANAGING YOURSELF: Preparing for this exam is not an easy feat but it is a learning experience. You should also enjoy and keep yourself happy, otherwise a bitter attitude will take a toll on you late

I think the best materials for every subject is different.

Ncert only for biology
Allen material/books for physics
For chemistry ncert+general concepts

NEET covers 80-85% syllabus from NCERT so I would suggest you to focus on that first properly as these will be helpful to make all your concepts strong and clear. Apart from these, you can follow below reference books -
Biology:
NCERT Biology of Class XI and XII
Trueman's Biology Vol 1 and 2
Objective Biology by Dinesh
Pradeep Publication's Biology
GRB Bathla's Publication's for Biology
Physics:
Concepts of Physics by H. C. Verma
NCERT- Physics Part 1 and Part 2
D C Pandey Objective Physics
Fundamentals of Physics by Halliday, Resnick and Walker
Problems in General Physics by I. E. Irodov
Chemistry:
NCERT Chemistry
Physical Chemistry by O.P. Tandon
Organic Chemistry by Morrison and Boyd for Organic Chemistry
Modern’s ABC of Chemistry for class 11th and 12th
Concise Inorganic Chemistry by J. D. Lee for Inorganic Chemistry
Dinesh Chemistrys
And to make it more easier to you, below I am mentioning few preparation tips as well -
1. Know the syllabus very well as this is the first step and you will have to understand what you are up against and this information you need before you plan and then begin the actual preparation.
2. Read standard books only as there are many books available in the market so it is advisable to use the books which make all your concepts clear and which are easy to understand.
3. Understand the weightage of topics properly and accordingly devote time because I wont suggest you to give more time to those topics which has less weightage but those topics should not be ignored.
4. Proper Revision plan should be followed as this would be helping you alot.
5. Mock Tests and Practice Tests should be done as this will help you to learn time management skills and this will also make you familiar with the exam pattern. Also, to make the best use of mock tests, better to check test analysis report properly as this will show where all you are still lacking or where all you have to work really hard.
Hope this helps!!!
