The National Testing Agency (NTA) is accepting objections to the provisional answer key for the NEET UG 2026 re-examination until June 28, 2026. Multiple reports say candidates must submit challenges through the official NEET website, neet.nta.nic.in, by the stated deadline (listed as 11:50 p.m.). The provisional answer key was issued for the re-exam taken by over 20 lakh candidates, with NTA also releasing the preliminary answer key on June 25.

To raise a challenge, candidates log in using their application number and password to access the challenge window associated with the answer key. The process is described as online-only, and challenges must be accompanied by a payment. Sources agree that the fee is ₹200 per question, and NDTV and the other outlet note that the fee is non-refundable. Where a challenge is accepted by an expert panel, a full refund policy is described.

After the objection period ends, NTA reviews the submissions and releases OMR-related information, followed by the final answer key. The final key is treated as conclusive for evaluation and result preparation, and NTA states that it cannot be contested further.
