how to clear her main? how are the questions ?

Hello,

To clear JEE Main, you need strong concept base and good practice.

First you need to complete NCERT along with textual exercises. Then you need to go for practice from Reference books or Coaching material. You need to dedicate 1hr approx. for each subject to be able to make it to NITs. Since it is a concept based exam, you need to focus on understanding the concept rather than just solving the numerical.

Questions in all levels of difficulty can be found in the exam paper. Few theory questions and simple numericals will also be there. But these alone won't make you pass. You need to carefully choose the questions to improve your accuracy.
