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.

Yes, several colleges convert a good JEE Main percentile directly into a fee waiver. Graphic Era's GECET-linked scholarships and UPES's merit scholarships can cut your fees by up to 50%.

No, JEE Main has not been mentioned as an accepted entrance exam for BTech at GLA University.

Candidates who want to apply for BTech at this institute must appear in their own entrance exam called GLAET. 

Admissions are based solely on scores obtained in this exam along with performance in PI rounds.
