Steps to calculate JEE Main Score using the answer key

The JEE Main 2021 Session 4 answer key will help students to calculate their scores easily. Candidates must keep in mind the marking scheme for the exam as per which the four marks will be awarded for every correct answer and one mark will be deducted for every wrong one. There will be no negative marking in the numerical section. Check the steps to calculate the probable JEE Main score below:

Step-1: Download the JEE Main 2021 answer key and response sheet.

Step-2: Match answers marked in the response sheet with the answer key

Step-3: For every correct answer add four marks and for every wrong answer deduct one mark from the total score. Do not deduct any mark for wrong answers in the numerical section.

Step-4: After matching all the answers, the final total will be the probable JEE Main score.

Note: JEE Main score thus calculated may vary from the final score.

JEE uses the percentile score to prepare the merit list. As a matter of practice the score is calculated up to 7 decimal places in order to avoid ties.
