Additionally, candidates can submit representations against the OMR grading by paying a non-refundable processing fee of ₹200 per question challenged.

Candidates must make the fee payment through debit card, credit card, or net banking by May 31, 2024, until 11:50 PM. Challenges will not be considered without receipt of the processing fee and will not be accepted through any other method.

"Challenges submitted by candidates will be reviewed by a panel of subject experts. If a candidate's challenge is found to be correct, the answer key will be revised and applied to all candidates' responses accordingly. The final result will be prepared and declared based on the revised answer key. Individual candidates will not be informed about the acceptance or rejection of their challenges. The answer key finalized by the experts after the review will be final," the notice stated.
