What to Do If You Find a Mistake in the Answer Key?

If you disagree with any answer in the UPSC ISS Answer Key 2026, you are allowed to raise an objection. Here is how you can do it:

• First, download the provisional answer key PDF for the relevant paper.

• Identify the question number(s) where you believe the answer is wrong.

• Prepare a written representation explaining your objection. Make sure to support your claim with references from standard textbooks or authentic study materials.

• Submit your representation to UPSC through the official channel mentioned in the answer key notification. This is usually done via post or online submission.

• UPSC will review all valid objections before publishing the Final Answer Key.

What Happens After the Provisional Answer Key is Released?

Once the objection window closes, UPSC's team of subject experts examines every representation submitted by candidates. If they find that an answer in the provisional key is incorrect based on valid references, they make necessary changes. After this review process, UPSC publishes the Final Answer Key on its official website. It is important to understand that final marks are calculated based on this final answer key, not the provisional one. These marks then determine the merit list and ultimately decide the selection of candidates for the Indian Statistical Service.
