After receiving all objections, the Commission evaluates each challenge carefully with expert review and supporting evidence. Based on this evaluation, UPSC may accept or reject the objections and then release the final answer key, which is considered the last and most authentic version.

No further objections are accepted after the release of the final answer key. The final result and cut-off are prepared strictly based on this final answer key, and it plays a crucial role in the declaration of the UPSC Prelims result.
