NTA

The NEET answer key challenge processing fee of INR 200 is non-refundable. NTA has specified the same on the information bulletin. As the answer key objection fee is non-refundable, candidates must crosscheck their challenges and be completely sure about the inaccuracy of the provisional answer key before sending out the objections. Given this information, candidates must not expect a refund of fee even if the NEET answer key challenges are found to be valid.

NTA released the final answer key for NEET exam on June 14, 2025. The NEET 2025 result was declared based on the NEET final answer keys. The provisional NEET answer key was released on June 3, 2025. Candidates could submit challenges or objections against the provisional answer keys till June 5, 2025.  

While NTA releases the NEET answer keys PDF, it does not release the detailed solutions or the answer-solving procedures and explanations. On the other hand, experts from coaching institutes release detailed NEET answer key solutions and candidates may refer to those to note the correct and effective way of solving a question. Hence, to understand if the answer solving methodology, test takers will not have any official source of reference, but would have to rely on the unofficial sources only.
