Yes, SSC charges a fixed fee per question for raising objections to the provisional answer key.
The fee is paid online and is non-refundable, even if your objection is accepted.
Objections must be submitted within the objection window through the candidate login — late objections are not accepted.
Quote the question ID and give a clear reason for each objection you raise.
SSC reviews all valid objections and then publishes the final answer key, which is used for evaluation.
