Common Mistakes to Avoid
- Do not file an objection without proof. The Commission will not look at an objection that has no proof from standard, authentic books.
- Match each objection to the question number in the model question paper on the RPSC website, not to your memory of the paper.
- Pay before you submit. An objection without the fee is not accepted, and the fee is not given back.
- Check everything before you press submit, because the Commission takes objections only once.
- Do not object if you did not sit these exams. Objections from anyone else are not considered.
- Do not leave it for the last evening. The link closes at 12:00 midnight on 16.10.2026, and a busy portal can be slow.
