JEE Main 2020: Most Important Chapters and Topics
JEE Main 2020: Most Important Chapters and Topics

Every aspirant who is going to appear for JEE Main 2020 wants to score maximum marks as the competition is increasing day by day. Every year lakhs of students appeared for the examination but only few get entry into the colleges of their choices.  Students always confused about the questions like:

What are the most important chapters for JEE Main 2020?

Do or die chapters for JEE Main?

What are the important topics of Mathematics for JEE Main 2020?

What are the important topics of Chemistry for JEE Main 2020?

What are the important topics of Physics for JEE Main 2020?

Will they get good rank if they cover only important topics?

First of all NTA does not allocate any weightage to any chapter. Students should concentrate on each and every topic/chapter of all subjects. But if students have less time for the preparation, then they can focus only on the important chapters as it is impossible to cover all chapters in a very less time.

After analyzing the pattern of last few years’ papers of JEE Main, Subject Experts have prepared a list of the important chapters along with the important topics. It will help you in your preparation for the examination.

Important Chapters of Mathematics for JEE Main 2020:

Students will definitely get good score in Mathematics if they prepare well for it. All the formulae should be at finger tips. If you face any difficulty while recalling any formula in the examination, then you will not be able to get good marks.

The important chapters of Mathematics are given below:
