GATE 2026 Answer Key

Answer keys, response sheets and challenges

The candidate response sheet records the responses entered, while the master question paper and answer key provide the examination's reference material. Question order can differ between the candidate view and the master paper. Match questions carefully before deciding that a response has been assessed against the wrong answer.

A useful challenge identifies the exact question, the disputed issue and a defensible technical explanation. A statement that a different answer appeared in personal notes is weaker than a derivation showing why the published answer or wording is inconsistent. Challenges must follow the official window and procedure; an old challenge guide does not establish that objections remain open after final results.

When estimating marks, use the correct question type and its penalty rule. An MSQ with an incomplete option set does not receive partial credit, and an incorrect NAT does not carry the MCQ penalty. Keep provisional estimates labelled as estimates until the final key and result are available.

If a question is revised or treated specially after challenges, use the final official treatment. Do not combine a provisional answer key for some questions with a final key for others without checking the differences. The final result incorporates the authority's decisions and remains the relevant document for admission.
