JEE Main 2019: Most Important Chapters and Topics

Every aspirant who is going to appear for JEE Main 2019 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. The National Testing Agency has scheduled JEE Main between January 6 and 20 in fully computer based test mode. Students always confused about the questions like:

What are the most important chapters for JEE Main 2019?

Do or die chapters for JEE Main?

What are the important topics of Mathematics for JEE Main 2019?

What are the important topics of Chemistry for JEE Main 2019?

What are the important topics of Physics for JEE Main 2019?

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.
