The supporting document should clearly establish why the provisional answer is incorrect and why the proposed answer should be considered.

What Happens After the CSIR NET Answer Key Challenge?

After the objection window closes, NTA will review the challenges submitted by candidates.

The provisional answer key may be revised based on the objections found valid during the review process. The final answer key will then be used for preparing the CSIR NET 2026 result.
