What's New in GATE Answer Key 2026?
GATE 2027 answer-key and challenge dates are not announced. Use the matching official key and candidate responses to estimate raw marks after release. Provisional answers can change; final evaluation uses the organiser's accepted answers.
GATE 2027 Answer Key and Challenge Dates
Table of Contents
The 2027 answer-key release and challenge dates have not been announced. The examination runs on 6, 7, 13, 14, 20 and 21 February, and results are scheduled for 19 March. No 2026 key is an active 2027 answer key.
Keep the paper code and session with each downloaded paper. Previous-year papers remain useful for practice, with their original year labels.
Provisional and Final Answer Keys
The provisional key supports the challenge process. A final key incorporates the organiser's decisions and is used for evaluation. A coaching solution is not the official provisional or final key.
For MSQ, check the full accepted option set. For NAT, check the accepted numerical value or range. A single remembered number is insufficient when the official key gives an interval.
How to Match the Key with Your Responses
| Match this | Why it matters |
|---|---|
| Year and paper code | A similarly named older paper is not the current key |
| Session / paper version | Questions and option orders can differ |
| Question identifier | Match the same master question, not just a remembered screen position |
| Question type and marks | MCQ penalties differ; MSQ/NAT have no negative marking |
| Official answer or accepted numerical range | Use the key's exact set or interval rather than a single coaching answer |
The candidate response sheet shows what you entered. The official key supplies what earns marks; neither should be substituted for the other.
How to Prepare an Answer-key Challenge
| Evidence | Include |
|---|---|
| Question identity | Paper code, session and exact question identifier |
| Disputed answer | Published key and the specific proposed correction |
| Technical explanation | Derivation, counterexample or calculation showing why the key is disputed |
| Supporting reference | Relevant textbook edition, page or authoritative source, not only a coaching opinion |
| Submission proof | Portal acknowledgement and required payment record |
Submit through the challenge facility within its notified window. A complete 2027 challenge-fee and deadline notice is not yet available, so an old fee should not be presented as the current charge. A disagreement needs a technical reason; merely preferring another option is not a substantiated objection.
Marks from the Answer Key
| Question | Correct | Incorrect | Blank |
|---|---|---|---|
| 1-mark MCQ | 1 | -1/3 | 0 |
| 2-mark MCQ | 2 | -2/3 | 0 |
| MSQ | 1 or 2, for the exact correct set | 0; no partial credit | 0 |
| NAT | 1 or 2, for an accepted numerical answer | 0 | 0 |
| Illustrative answers | Calculation | Raw marks |
|---|---|---|
| 12 correct and 3 wrong one-mark MCQs | 12 - 3/3 | 11 |
| 15 correct and 3 wrong two-mark MCQs | 30 - 6/3 | 28 |
| 4 correct two-mark MSQs | 4 x 2 | 8 |
| 6 correct two-mark NATs | 6 x 2 | 12 |
| Total | 11 + 28 + 8 + 12 | 59 / 100 |
This calculation gives raw marks. The GATE score formula needs the official paper benchmarks, and multi-session normalisation requires session statistics. Do not label this total a rank prediction.
GATE Answer Key FAQs
Can I challenge an answer because a coaching key differs?+
A different coaching answer can prompt a recheck, but it is not sufficient proof by itself. Identify the exact question and support the proposed correction with a derivation or authoritative reference through the notified process.
Can an MSQ have more than two correct options?+
Yes. Select the entire correct set shown by the key. GATE awards no partial credit for an incomplete set.
Should a NAT answer match every decimal in a solution?+
Use the accepted value or range in the official key and the precision requested by the question. A answer explanation's extra decimal places do not by themselves define the accepted interval.
Can I use a 2026 key to calculate 2027 marks?+
No. The year, paper and session must match the questions attempted. Older keys belong only to their dated papers.
Is the answer-key score my official GATE score?+
It is a raw-marks estimate. The official standardised score uses additional paper-level benchmarks and, for multi-session papers, normalised marks.
