Hi Ishaan,

JEE Main's questions are based on the syllabus of NCERT.  Difficult level of questions is a bit harder than the NCERT. If you have studied NCERT thoroughly, you would be able to solve most of the questions.

Every year, you will find around 3-4 questions which have been asked before.

Hello aspirant,

The jee main paper is now set by NTA. Nobody knows from where the question will come. It's unpredictable. You need to practice more and more. Its not that if you solve last 40 years question you will be attempt all. But you need to practice everything.

Thank you.
