OPSC Assistant Fisheries Officer Answer Key 2026: Download PDF & Raise Objection by 12 Oct
If you sat for the OPSC Assistant Fisheries Officer written exam on 26 September, your wait for the answer key is over. The Odisha Public Service Commission released the provisional answer keys for both Paper-I and Paper-II on 1 October 2026 — and if something in the key looks wrong to you, you have until 12 October to say so online.
That objection window matters more than most candidates realise. This is a provisional key, which means OPSC will actually read valid challenges and correct the key before the final version comes out. Every corrected answer can shift your score — and with negative marking in play, even one reversed question changes where you stand.

How to Raise an Objection (Before 12 October)
Objections are accepted online only — there is no offline or email route. The portal is opscechayan.in, OPSC’s e-Chayan platform.
- Log in to opscechayan.in with your credentials.
- Open the objection link for the AFO provisional answer key.
- Select the question you want to challenge and state your reason clearly.
- Attach supporting evidence if the portal asks for it — a vague “this seems wrong” carries no weight.
- Submit before the deadline. Once the window closes on 12 October, the key becomes final for scoring and no further challenges are entertained.
One practical note: challenge only the answers you can back up. OPSC reviews each objection on merit, and questions that draw no valid objection are treated as final.
Estimating Your Score
The marking scheme is straightforward:
- Correct answer: +1 mark
- Wrong answer: −0.25 mark
- Unattempted: 0
So: (correct answers × 1) − (wrong answers × 0.25) gives you a rough estimate per paper. Do this for both papers separately, since the key covers each one independently.
What Happens Next
After 12 October, OPSC will go through every valid objection and publish a final answer key. The written exam result follows the final key — and candidates who clear the cutoff move to the interview stage. Keep an eye on opsc.gov.in for the final key announcement; there is no fixed date for it yet.
