When a student prepares for NEET UG, it is important for him / her to know the complete syllabus. Even in syllabus, it is a smart thing to do to know about most important chapters for NEET 2018 (or NEET 2019 if appearing in 2 years). One who attends coaching classes may get expert tips from teachers there about which chapters to pay more attention to. But what about those who have not been told or have no idea about it? Well, this article here is a starting point.

How to start preparations for NEET 2018 or NEET 2019?

If you are planning to appear in NEET 2018, then your first goal should be to complete the syllabus. For theory, you must refer to NCERT textbooks as they cover the NEET syllabus most comprehensively. Next, you can use one or two books for each subject to practice MCQs. You should complete these two steps for all chapters by December.

If you will appear in NEET 2019 then you have a good time to plan and prepare. Make sure that you take down notes for each chapter so that when the time comes to revise, you can do it well. Theory should be studied from NCERT along with state board textbooks if you have different books.

Let us first take a look at marks distribution between class 11 and 12 topics

Subject Class XI Class XII
Number of questions Total marks Number of questions Total marks
Physics 19 76 26 104
Chemistry 16 64 29 116
Botany 28 112 22 88
Zoology 25 100 15 60
Total 88 352 92 368

As can be seen, the marks distribution is almost equal between the two classes. Hence, it is of utmost importance to study chapters taught in class 11 as well as class 12 properly.

What are the do or die chapters for NEET 2018 and NEET 2019?

Before we dive into answering this question, a little word of caution: CBSE has simply laid down a syllabus for NEET exam. It has not specified any weightage to any chapter. Most important chapters for NEET 2018 and NEET 2019 are recommended on basis of past year paper analysis.

Important Chapters for NEET 2018 and NEET 2019In NEET 2017, maximum questions were from NCERT.

So firstly we will look at the sections which had maximum importance in the last National Eligibility cum Entrance Test (NEET UG).

Physics: Mechanics is the most important topic. 12-13 questions were asked on it last time.

Chemistry: Organic Chemistry dominates the chemistry question paper. 14-15 questions were from topics related to it.

Biology: There was a more uniform distribution of questions in Biology. There was no single unit or topic from which more than 6 questions were asked. Hence it would be wrong to deem any one single chapter most important as all are important.

    • Marking scheme of NEET 2018 is +4 , -1.

      As far as topic wise weightage is concerned, it is as per analysis of past year papers. As per CBSE all chapters are equally important, and CBSE can give any question from any of the chapters that are in the syllabus of NEET. The important chapters of NEET are only for reference. Its purpose are as follows.

      a. If you have very less time, and can only study some chapters, then it is better to focus on chapters with more weightage as per analysis.
      b. During revision, you can revise these chapters more vigorously.

      When it comes to studying, you should definitely study ALL chapters, and not just the ones given here.

  6. Sir/mam
    Can I qualify neet exam only with the help of ncert of all three subjects viz.bio , physics1 and 2 , chemistry1 and 2 of both 11 and 12 class.

    • Hi Mohammad
      you should give your priority to the ncert books because many questions of bio including diagrams comes from ncert and more over should read each and every chapter properly from chem and phy .
      Not only ncert you can refer previous year question paper and notes that will help you score good marks

      All the Best !!
