This  syllabus  will  be  very  helpful  in  your  preparation  because  it  will  let  you know  the  topics  and  chapters which are included  in  your  examination   , so go well  through  your  syllabus  and  plan your  studies  so  that  you  can  score  well in  your  jee main  examination.

But yes,

As CBSE and many other state boards have reduced their syllabus JEE Mains 2021 examination pattern is changed a little bit in order to provide more internal choices.

Now,

In your JEE Mains 2021 examination paper 1 , there will be a total of 90 question instead of only 75 questions which used to be there earlier  , and out of  those 90 questions, only 75 questions are  to be attempted. S

And these questions are from three subjects :-

*  30 questions from physics.

* 30 questions  from Chemistry .

* 30 questions  from maths.

The 30 questions  in each Subject,  will be divided into two sections -

*Section A :- A Section will contain 10 MCQs or multiple-choice questions.

* Section B :-

it will contain 10 numerical value questions whose   answers are to be filled in by you as a numerical value. You  have to attempt only 5   questions out of the  total 10 numerical value questions. So, now there is internal choices .
