Steps to calculate JEE Main Score using the answer key

Students can easily calculate their scores using the JEE Main 2021 answer key. As per the JEE Main marking scheme, students can award themselves four marks for every correct answer and deduct one mark for every wrong one. There will be no negative marking in the numerical section.

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.
