How do I report a wrong answer key in a PYQ?

The best way to flag a suspected answer key error: use the Report button on the question card itself. It's the small icon on the question — tapping it sends a flag to the moderation queue with the question ID already attached, so there's no manual lookup needed on our end. If you'd prefer to provide more detail, posting here works too — include the year, slot, section, and question number, plus your answer and a brief explanation of why you think the official answer is incorrect. We cross-check against the official CAT answer key and at least two independent solution writeups before making any change to the answer or explanation. Thank you for flagging it — these reports are genuinely useful. A question with a wrong answer key is worse than a missing question, and they're not always easy to catch in a bank of hundreds.
