Important topics to be prepared for JEE Main 2018

It is the largest engineering entrance exam in India for admission into the various IIIT’s, NIT’s and CFT’s. Huge number of aspirants appear for this exam every year therefore, it is a challenge to crack JEE Main 2018. The key to crack this exam is full dedication and concentration with the right approach. So every aspirant wants to know what are the important topics from the exam point of view.

Whenever you start preparing, you need a proper time-table. Once you prepare your plan then your first step is to go through the JEE Main Syllabus; When you are reviewing the syllabus you may also try to find-out those topics which are really important for JEE Main 2018 and need to be prepared.

Why is it important?

If you are going with vast and wide topics which are not important for JEE Main point of view, you are wasting your time. Also, you are leaving those topics which are really important which can affect your result.

Some questions/topics are those, which you don’t understand but you have to be prepared for them too.


So If you try to follow the experts then they will suggest you to not leave any topic and prepare them according to their weightage.


Some of the questions asked by students to experts through different forums are as follows:  



  • What are the important topics for JEE Main according to the weightage?
  • What are the important topics to be prepared for JEE Main 2018?
  • I prepared only one year, can you suggest some important topics which must  come into the exam?
  • Which topics should I focussed more to crack JEE Main 2018 with good score?



So once you analyze all the questions you will get what everyone wants to find-out what are the important topics for JEE Main 2018?


Now I am discussing some important topics for every subject i.e.
