NEET Chapter wise Weightage & Important Chapters for NEET 2021 | For cracking NEET, it is important that you know which are the important chapters for NEET and what is the chapter wise weightage of each chapter in NEET. With NEET important chapters in hand, you can focus more on those chapters. Chapter wise weightage for NEET tells us exactly which chapters carry more questions and accordingly more weight in the NEET examination. As such, don’t commit the mistake of taking these important chapters for NEET lightly or ignoring these chapters.
As NEET is a highly competitive exam, you cannot risk ignoring the important chapters and the chapters having more weightage in the NEET exam. Once you have familiarised yourself with the NEET syllabus and you know which important topics you need to prepare well, you should prepare strategically for cracking NEET; your preparation becomes easier, focussed and streamlined. In this article, CareerOrbits’ experts have analysed the chapter wise weightage for NEET 2021 which helps you to plan and manage your preparations for the NEET exam.
In the official syllabus for NEET, specific weightage is not assigned to any chapter. So, firstly and most importantly, you should cover each and every topic and chapter in NEET syllabus and clear your basics in all the chapters and not just the important chapters for NEET.
Based on the analysis of the previous year NEET question papers, we are providing a list of all the important chapters for NEET and the chapter wise weightage in every subject in NEET.

NEET Mock Tests as per the New Pattern (for class 11th students)
Full syllabus mock tests for NEET covering all chapters. The new pattern NEET Mock Tests for NEET 2021 aspirants will help them prepare the as per the latest NTA pattern. |
there is a variation in marks of botany and zoology...previously both the subjects are for 180 marks...but now botany is for 200 and zoology is for 160 according to the weightage...will this change occur in neet 2020 examination?
The total marks for Botany and Zoology put together would be 360, as confirmed in the latest offical notification also. NTA does not prescribe relative weightage of zoology or botany within the overall 360 marks. There could be variations year to year in the proportion of marks for Botany and Zoology.
This blog describes the expected weightage based on our expert analysis of the latest trends. The actual weightage of topics in NEET 2020 could be different from what is stated here in this blog.
As per the announcement NEET, JIPMER and AIIMS are merged. So, will the questions be purely based on NCERT, nothing out from NCERT?? Will biology and chemistry questions not be asked from outside of NCERT??
Tejasvi, the announcement simply states that selection for JIMPER and AIIMS shall also be made through NEET. The announcement nowhere states that JIPMER and AIIMS admission tests have been merged into NEET.
If you look minutely, there's a lot of difference in the question that you have asked and the announcement made by the Govt. In case the tests are merged, yes obviously there could have emerged a new pattern, probably accommodating the difficulty levels of AIIMS and JIPMER too. But the simple announcement is that selection for AIIMS & JIPMER would also be through NEET.
So, we expect that there would be not much changes in the level of questions or pattern of questions in NEET 2020. This should largely conform to the difficulty levels and pattern as per NEET 2019, with may be, minor variations.
