JEE Main 2018 is a national level entrance exam conducted by CBSE. Paper 1 of JEE Mains acts as the gateway for undergraduate engineering admissions, and Paper 2 does that for undergraduate architecture admissions. As the days towards JEE Main 2018 get closer, one question that keeps popping in a future JEE topper’s mind is “which are the most important chapters for JEE Mains 2018 or JEE Mains 2019?

After exam check JEE Main 2018 answer key, result.

There are many variations of this question. You may be wondering “what is the chapter wise weightage of JEE Mains physics?” or “what is the chapter wise weightage of JEE Mains chemistry?” or “what is the chapter wise weightage of JEE Mains mathematics?”.

Here, we answer these questions.

To start with, it should be clear that the exam conducting body CBSE does not allocate any weightage to any chapter. For CBSE, all chapters are important.

If you are preparing for JEE Mains 2019 then we would suggest that you go through the syllabus of JEE Main and prepare all subjects. Save this page and refer to it when you have lesser time left for your exam.

But of course, if you are preparing for JEE Mains 2018 and are in your last lap of preparation, then this article here is important.
