The very first thing that you need to know while preparing for the NEET 2020 is that syllabus of the exam. Without knowing syllabus, you will not get a proper direction in the subject and you will not be able to score good marks. For preparing theory questions from the subjects physics, chemistry and biology (botany and zoology), you need to take help of NCERT textbooks which covers almost all the NEET syllabus. For practicing MCQ questions, choose at least 2 books for each subject and refer them. Note that, you need to prepare short notes of each chapter of the subject which will help in your final preparation. But, before going to start your exam preparation, it is also necessary and very important for you to check out the distribution of marks in each subject for the Class XI and XII syllabus. Also check the important chapters that have more NEET chapter wise weightage and that cover more number of questions. By preparing those chapters or units thoroughly, you will get maximum number of marks in the exam which leads you to qualify the test easily. We have given all those details below and we advise you to refer them.
NEET Chapter Wise Weightage PDF
Candidates can go through the topic wise weightage and the overall NEET chapter wise weightage 2020 from each subject of the NEET paper from the below given tables. This is the previous year weightage and once the exam conducting authorities issue the chapter wise weightage for this year, we will update the PDF in this post and we advise the candidates to keep watching this post for the update.
NEET Marks Distribution for All Subjects in Class XI and Class XII
Candidates can check out the Number of Questions along with the marks distributed for each subject from the syllabus of Class XI and Class XII below. Based on this marks distribution, one can give more importance for the subjects of the class from which the candidate can score more marks.
| Subject | Class XI | Class XII | ||
| No. of Questions | Total marks | No. 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 |
When it comes to the overall questions and marks in the NEET paper, there are a total of 180 questions for which each question is worth of 4 marks. All the questions are of multiple choice questions. From physics and chemistry you will get 45 questions whereas from Biology 90 questions i.e., 45 from botany and 45 from zoology.
