The IIT JAM exam answer key and your response sheet are two different documents. The key shows the correct answers. The response sheet shows what you marked. In 2026, the response sheet was called candidate responses.
| Document | What it shows | When in 2026 |
|---|---|---|
| Candidate responses | Your own recorded answers | From 18 February 2026 |
| Master question paper | The full paper for your code | From 18 February 2026 |

| Final answer key | Answers after review, with cutoff marks | After the result |
How do I match my responses with the IIT JAM answer key?
Match each answer in the IIT JAM exam answer key by question text, not by screen order. IIT JAM questions appear in a random sequence on the screen. Your screen order can differ from the master question paper.
Work section by section through the IIT JAM exam answer key. Section A has 30 MCQs. Section B has 10 MSQs. Section C has 20 NAT questions. Mark each one as correct, wrong or not attempted.

How to Calculate IIT JAM Score Using Answer Key 2027?
Your IIT JAM score is your raw marks out of 100, worked out from the IIT JAM exam answer key. There is no percentile and no normalisation. The scheme below comes from the 2027 Information Brochure. The same scheme applied in the 2025 and 2026 brochures.
| Question type | Correct answer | Wrong answer |
|---|---|---|
| MCQ, 1 mark (Section A) | +1 | minus 1/3 |
| MCQ, 2 marks (Section A) | +2 | minus 2/3 |
| MSQ, 2 marks (Section B) | +2 only if the set matches the key | 0, no partial marks |
| NAT, 1 or 2 marks (Section C) | +1 or +2 | 0 |
Unattempted questions give zero in every section. The paper has 60 questions and 100 marks. Section A is 50 marks, Section B is 20 marks and Section C is 30 marks. The IIT JAM 2027 exam pattern page has the full section table.
How do I work out my IIT JAM marks with an example?
This example uses the official scheme to check a score against the IIT JAM exam answer key. The answers are made up to show the arithmetic.
- Section A, 1-mark MCQs: 6 correct and 2 wrong. Marks: 6 minus 2/3 = 5.33.
- Section A, 2-mark MCQs: 15 correct and 3 wrong. Marks: 30 minus 2 = 28.
- Section B: 6 MSQs match the key exactly. Marks: 12.
- Section C: 7 correct 1-mark NATs and 6 correct 2-mark NATs. Marks: 7 plus 12 = 19.
The total is 5.33 + 28 + 12 + 19 = 64.33 marks. Compare your total with the IIT JAM cutoff 2027 page after the result.
Score Calculation: Frequently Asked Questions
1. Can IIT JAM marks be negative?
Yes. Only Section A has negative marking. In 2026, the lowest raw marks across the seven papers ranged from minus 6.67 to minus 14.
2. Should I guess in Section B and Section C?
A wrong answer costs nothing there. Section B and Section C have no negative marking. A blank gives zero, so a guess cannot lower your score.
3. Does the IIT JAM exam answer key decide my rank?
Your marks decide your rank. The key decides your marks. IIT JAM awards a separate All India Rank for each paper.
4. Is there partial marking in IIT JAM MSQ questions?
No. An MSQ earns 2 marks only when your selected options match the IIT JAM exam answer key exactly. A wrong or incomplete selection earns zero and carries no negative mark.
5. When should I score myself with the IIT JAM exam answer key?
As soon as the responses open. Score yourself with the IIT JAM exam answer key early. Then plan for the cutoff.

He plans the organic content strategy and also owns the structured data that feeds it. He works with a team of product managers, engineers, QA, designers, writers, and SEO specialists. Together they create guides for Indian students and parents on colleges, entrance exams, and studying abroad. Atul has built a step-by-step content process that uses AI tools with a human in the loop. Every page goes through several stages. It starts with research, where each fact is checked on the official source. A second, independent source is then used to confirm that the fact is correct and the latest. Third-party sites are used only to spot differences and are never treated as a source. Before writing, the team studies what students actually search for and what the top results leave out. This study covers Google, Bing, DuckDuckGo, ChatGPT, and Perplexity, including AI answers and “People also ask” questions. Pages written by Atul are in plain English that can be understood in one read, and they open with the question the reader is most likely to have. Before a page goes live, every number, name, date, and fact is checked again against its official source. Finally, an editor reads and humanises every page, however good the draft is. Atul believes that advice on education should be simple, honest, and based on official facts. Fees and figures should come with their source. A student should be told clearly when a college is not the right fit.
