Hi

In your JEE Mains 2021 examination paper 1 , there will be a total of 90 question, out of which 75 questions are  to be attempted

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 20 MCQs or multiple-choice questions. Four options will be there  out of which one will be correct . And you have to choose the correct option.

* Section B :- it will contain 10 questions whose answer is a numerical value , no options will be there ,  you need to enter or type your answer  i. e numerical value .You  have to attempt only 5   questions out of the  total 10 numerical value questions .

So, out of 30 questions in each subject only 25 questions are to be attempted, so in total  25 x 3 = 75 questions out of 90 questions are to be attempted.

Each question carries 4 marks

Exam is conducted for a total of

= 75 x 4
= 300 marks

Marking scheme :-

*four marks will be awarded for your every correct answer
* 1 mark will be deducted for your every wrong answer in case of section A /MCQs
* no marks will be deducted for your wrong answer in case of in case of section B/numerical value question
