Hello,

NO, NCERT contains 65-70% of the total syllabus for NEET from which you won't get 600+ marks. Along with NCERT practice reference books, sample papers and give mock test at regular interval to improve your time management skills.

Hope this helps you,

All the best for your future.

It is not mandatory to join any coaching centre for Neet preparation. If you are dedicated enough and have enough potential, you'll surely get good marks. Being one of the toughest exams, one needs a lot of hard work and determination to get good score in Neet.
First you should go through the entire syllabus. Then make a proper a programmatic study schedule.
Instead of choosing a random topic from the syllabus, you must break your preparation into sections. Sub-topics from each section should be selected and then strategy on clearing concepts must be made.
Whenever any doubt pops up in your mind, try to solve it by then.

• According to toppers and experts, NCERTs are the best book to start your preparation with. So you must focus on NCERTs first. Many questions are directly asked from NCERTs.
• Don't forget about negative marking. Answer if and only if you are sure about that.
• Revision is a must thing. At least 10 days before the examination you must start your revision along with short notes.
• Once you complete your syllabus give mock tests once you are done with your syllabus. Solve previous years' exam papers available on Internet. Then analyse it. Find out your weak areas and work on them. Solving previous year exam papers are the most important thing for Neet preparation.
• Read all the chapters, ignoring low weightage chapters and studying only most important chapters can cost a lot. So study from first to last. During last few days of examination, you can focus more on the chapters with high weightage.

Going by last few years' question analysis, we have the chapter wise weightage.

However, there are chances that Neet 2021 syllabus will be reduced as the academic year has been delayed and due to this pandemic all educational institutes are closed so it is difficult to complete the entire syllabus. To complement that, CBSE has reduced the syllabus 30%.
However, Careers360 has come up with Neet knock out package to help medical aspirants in their preparation. http://learn.careers360.com/knockout-neet-may/
