How does the NEET answer key challenge work and is the fee refunded if I am right?

Previous-year referenceApproved by M.B. Patil Education admissions team, 23 Oct 2026 · source-checked 22 Oct 2026

Short answer

After the exam, NTA publishes a provisional answer key, and you can challenge it online by paying a non-refundable processing fee of ₹200 per answer challenged. A panel of subject experts checks each challenge; if one is found correct, the answer key is revised for all candidates and the result is based on the final key. The bulletin calls the fee non-refundable and does not mention any refund for a correct challenge.

Based on the NEET (UG) 2026 Information Bulletin and NTA's 16 July 2026 result press release. The 2027 bulletin hasn't been published yet — rules can change, so check it when it is.

Who this applies to

All NEET (UG) candidates who appeared in the exam

The rule, explained

Challenges must be made within the period given in NTA's Public Notice. The exact dates are announced on the NTA website after the exam.

No individual candidate is told whether their challenge was accepted. The final answer key is put on the NTA website before the result.

Separately, NTA displays the scanned OMR answer sheets and the responses recorded by the machine. You can challenge the OMR grading by paying a non-refundable processing fee of ₹200 per question challenged.

There is no re-checking or re-evaluation of answer sheets.

Example: In 2026, NTA published the provisional answer key on 25 June 2026, with the challenge window open from 25 to 28 June 2026. The final answer key was published, and the result declared, on 16 July 2026.

What the official document says

Candidates will be given an opportunity to make an online challenge against the provisional Answer Key by paying a non-refundable processing fee of ₹ 200/- per answer challenged, within a specified period as indicated in the Public Notice.
