NEET 2020 – Chapter wise weightage and Important Chapters.

by admin

To score good marks in 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.

NTA is the respective body which organizes NEET UG exam for aspirants seeking admission to MBBS and BDS programmes.  The exam pattern of NEET will also be defined by NTA.  It is advisable for the candidates to completely go through the NEET exam pattern because it helps in understanding the structure of paper such as the number of questions, duration of exam, marking scheme, negative marking, syllabus etc. As per NEET examination pattern, the question paper includes 180 objective type questions from the subjects Physics, Chemistry, Biology (Botany and Zoology) studied in class 10+1 & 10+2. The maximum time given to complete the test is 3 hours.

As per NEET exam pattern, 4 marks to be given for a right response and 1 mark will be deducted for every wrong answer

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.

First, let’s have a look at the distribution of marks between Class 11 and Class 12 syllabus in the NEET exam.
