What this calculator does

It reads your official NTA response sheet, compares every answer with the official answer key, and applies the same marking scheme the exam uses. In a few seconds you get your total out of 300, your marks in Physics, Chemistry and Mathematics, your accuracy, and a question by question review showing what you marked against what was correct.

No sign up, nothing saved. You paste a link, you get a result. Your response sheet is not stored and not shared.

How to get your response sheet link

Open the official JEE Main website and go to the candidate login
Log in with your application number and password, or date of birth
Open the response sheet for your paper and shift
Copy the full URL from the browser address bar
Paste it in the box above and press Calculate My Score

Copy the link of the response sheet page itself, not the login page. NTA also closes this window after a few days, and the link stops working once it does. Save a PDF copy of your response sheet while it is still open.

Marking scheme used

Response	Marks
Correct answer	+4
Incorrect answer	-1
Unattempted	0
Question dropped by NTA	+4 to every candidate
Two options found correct	+4 for either option

Numerical questions carry the same penalty as multiple choice ones. This is where most students lose marks without realising it, because a guessed numerical value is almost never right.

What your result shows

Part	What you see
Total score	Marks out of 300, with correct, incorrect and unattempted counts
Subject split	Physics, Chemistry and Mathematics out of 100 each
Accuracy	Correct answers as a share of what you attempted
Question review	Every question with your answer, the correct answer and the marks earned

Marks, percentile and rank are three different things

This calculator gives you marks. The result NTA publishes is a percentile, and the rank comes later. Mixing these up leads to a lot of unnecessary panic every year.

Term	What it means	Who produces it
Marks	Raw score out of 300 from the answer key	This calculator
NTA score	Percentile showing your position within your shift	NTA, with the result
All India Rank	Final rank after both sessions, using the better NTA score	NTA, after session 2

Two students with the same marks in different shifts can get slightly different percentiles. That is normalisation doing its job, not a mistake.

What to do after you see your score

Check the answer key properly. If a question looks wrong, raise an objection within the window. The fee is refunded if your objection is accepted.
Look at accuracy, not just the total. Low accuracy with many attempts means negative marking is eating your score, and that is fixable in a month.
Compare with last year's closing ranks for the branches you want, from the final JoSAA round.
Plan session 2. The better of the two scores counts, so a second attempt can only help you.

Common questions

Ques. Is this calculator free?

Yes, and no account is needed. Paste the link and you get the result.

Ques. Is my response sheet stored anywhere?

No. The link is read to work out your score and nothing is kept afterwards.

Ques. Why is my score different from another calculator?

Usually because of dropped questions or a changed answer key. We use the latest key available at the time you calculate. If the final key changes an answer later, your score can move slightly.

Ques. Does this give my rank or percentile?

No. It gives marks. Percentile depends on how everyone in your shift performed, which only NTA can compute.

Ques. Can I calculate for both sessions?

Yes. Run it once with each session's response sheet link and compare.

Ques. The link is not working. What should I do?

Check that you copied the response sheet page URL and not the login page, and that NTA has not closed the window. If it is closed, nothing can be calculated from it.

Ques. Does it work for Paper 2 as well?

It is built for Paper 1. Paper 2 has a drawing section that cannot be scored from a response sheet.

This score is an estimate for your own planning. The result declared by NTA is final.
