Follow these steps once UPSC releases the provisional answer key.
1
Access the Provisional Answer Key
UPSC has released the official provisional answer key. Log in to the QPRep portal at upsconline.nic.in/login to view the key and your OMR responses. The representation window closes at 6:00 PM on 31 May 2026.
2
Compare with Your Answers
Download the provisional key for your question paper set (A/B/C/D). Compare each answer with what you marked. Note down questions where you believe the official answer is incorrect.
3
Visit the QPRep Portal
Navigate to the QPRep (Question Paper Representation) portal, accessible through the UPSC website. This is the dedicated portal for submitting objections.
4
Login with Your Credentials
Login using your UPSC registration number and other credentials used during the application process. Only candidates who appeared for the exam can access this portal.
5
Select the Question to Challenge
Choose the specific question number you wish to challenge. Clearly state which answer option you believe is correct and why the marked answer is wrong.
6
Provide Justification with Evidence
Write a clear, concise justification explaining why the provisional answer is incorrect. Cite specific page numbers, sections, or quotes from your reference sources.
7
Attach Credible References (3+)
Upload or cite at least 3 credible references supporting your claim. These must be from standard sources like NCERT textbooks, official government publications, or peer-reviewed journals.
8
Review and Submit Before Deadline
Double-check your objection for accuracy, completeness, and clarity. Submit before the deadline — no extensions are granted. Save your submission confirmation.

UPSC requires references from authoritative sources. Coaching institute materials and user-generated content are not accepted.

Economic Survey 2025-26, Volume 2, Chapter 8, Table 8.3

Coaching Institute Notes/KeysNot Accepted
Answer keys or study material prepared by coaching institutes.
Not accepted — these are opinions, not authoritative sources.
Wikipedia / Online BlogsNot Accepted
Wikipedia articles, personal blogs, or unverified online sources.
Not accepted — these are user-generated and not authoritative.
News ArticlesNot Accepted
Newspaper reports or news website articles (unless quoting official data).
Generally not accepted unless citing a government press release or official data.
Tips for Filing Strong Objections
Increase the chances of your objection being accepted by following these guidelines.
Be Specific with Citations
Cite the exact book name, edition, chapter number, page number, and paragraph. Vague references like "as per NCERT" are insufficient.
Quote the Exact Text
When citing a source, quote the exact relevant sentence or paragraph that supports your answer. This makes it easy for the expert panel to verify.
Use Multiple Independent Sources
Provide at least 3 references from different types of sources (e.g., one NCERT, one government publication, one peer-reviewed source). Consistency across sources strengthens your case.
Explain, Do Not Just Assert
Do not just say "Option B is correct." Explain why the marked answer is wrong and why your answer is right, with a clear logical chain supported by evidence.
Focus on Genuinely Disputed Questions
Only challenge questions where you have strong evidence. Check if coaching institutes also disagree on the answer — questions where multiple institutes differ are more likely to have legitimate issues.
Submit Well Before the Deadline
Do not wait until the last hour. Portal traffic may be high near the deadline, and technical issues could prevent submission. Aim to submit at least a day before the cutoff.
What Happens After You File an Objection?
Understanding the review process and outcome.
Expert Panel Reviews All Objections
UPSC appoints subject matter experts to review all objections received. The panel evaluates the evidence provided and determines whether the provisional answer needs to be changed.
Final Answer Key Published
After reviewing all objections, UPSC publishes the final answer key incorporating any valid corrections. The Prelims result is based entirely on this final key.
No Individual Communication
UPSC does not individually inform candidates whether their specific objection was accepted or rejected. You can determine the outcome by comparing the provisional and final answer keys.
Common Mistakes to Avoid
Avoid these pitfalls that weaken your objection or render it invalid.
Filing without credible evidence
Simply stating "I think option B is correct" without providing references will not be considered. Every objection needs at least 3 credible references.
Citing coaching institute keys as evidence
Coaching institute answer keys are unofficial opinions. UPSC does not consider them credible sources, regardless of the institute's reputation.
Missing the submission deadline
The objection window has a strict deadline. No late submissions are accepted. Set reminders and submit well before the last date.
Challenging correctly answered questions
Do not file objections for questions where you are not confident the official answer is wrong. Focus on genuinely disputed questions where you have strong evidence.
Vague justifications without specific citations
Writing "as per NCERT" without specifying the book, chapter, page number, and exact content does not constitute a strong objection.
Not saving the submission confirmation
Always save or screenshot your submission confirmation. UPSC does not communicate individual outcomes, so this is your only record.
Make the next attempt count.
Whether you cleared or fell short, the next stage is practice under exam conditions — full-length Prelims tests with Sherlocking analysis, or the Mains programme if you are through.

Frequently Asked Questions — Answer Key Objections
Who can file objections against the UPSC Prelims 2026 provisional answer key?
Only candidates who actually appeared for the UPSC Civil Services Preliminary Examination 2026 can file objections. You will need your registration number and login credentials to access the QPRep portal on the UPSC website.
Is there a fee to file objections?
UPSC has not announced any fee for filing objections for the 2026 Prelims. Other examination bodies like NTA charge a nominal fee per objection (refundable if the objection is accepted). This page will be updated when UPSC announces the specific terms.
How many objections can I file?
There is no confirmed limit on the number of objections a candidate can file. However, each objection must be supported by credible evidence. Filing frivolous or unsupported objections is unlikely to help and may clutter the process.
Can I use coaching institute answer keys as a reference for my objection?
No. Coaching institute answer keys are not considered credible sources by UPSC. Your objection must be supported by standard references such as NCERT textbooks, official government publications, peer-reviewed journals, Supreme Court judgments, or Gazette notifications.
What happens if my objection is accepted?
If an objection is found valid by the expert panel, the answer key for that question is revised in the final key. All candidates benefit from this correction — it is not limited to the person who filed the objection. UPSC does not individually communicate whether a specific objection was accepted or rejected.
What if a question has no correct answer or multiple correct answers?
If the expert panel determines that a question has no correct option or multiple correct options, UPSC may award marks to all candidates for that question or accept multiple correct answers. This has happened in NEET and other exams that follow the objection mechanism.
Can I file objections after the deadline?
No. The objection window has a fixed deadline, and no submissions are accepted after it closes. Monitor the UPSC website and this page for the exact deadline once announced.
Will the provisional key affect my score calculation?
Your final score is based on the final answer key (after objections are resolved), not the provisional key. However, the provisional key gives you a very close estimate of your actual score. Typically, only 2-5 questions see changes between provisional and final keys in similar exams.
Know Your Score Before the Official Key
