Choose the National Defence Academy and Naval Academy Examination (II), 2026 from the available examinations.

Make sure that you select the correct examination before proceeding with your registration.

Step 4: Select the Relevant Paper

The NDA 2 2026 written examination consists of two papers:

• Mathematics – 300 marks
• General Ability Test (GAT) – 600 marks

The official UPSC provisional answer-key page provides separate answer-key documents for Mathematics and GAT. 

Select the paper containing the question against which you want to raise a representation.

Step 5: Identify the Question Carefully

Before submitting the representation, compare the official provisional answer key with your question paper.

Pay particular attention to:

• Paper
• Question number
• Booklet series
• Question wording
• Answer option given in the provisional key

NDA question papers are issued in different booklet series, so candidates should verify the correct series before raising a representation.

Step 6: Explain the Objection

Clearly explain why you believe the answer provided in the provisional key is incorrect or why the question contains an issue.

A useful representation should identify:

Question: Mention the exact question number.

Issue: Explain the discrepancy in the question or answer.

Correct Answer: State the answer you believe should be considered correct.

Reason: Provide a concise explanation supporting your claim.

Step 7: Provide Supporting Evidence

Candidates should support their representation with reliable references wherever applicable.

For example, depending on the question, candidates may refer to:

• NCERT or standard textbooks
• Government publications
• Official government websites
• Standard academic reference books
• Authentic subject-specific sources

UPSC's QPRep process requires candidates to provide supporting material for their representations. In its 2026 implementation, UPSC has stated that representations are reviewed by subject experts along with the supporting material submitted by candidates. 

Step 8: Submit the Representation

Review all the information entered in the QPRep portal before submitting it.

Once the representation is submitted, save the acknowledgement or submission details for your records.

Candidates should submit their representations within the prescribed window. UPSC's general instructions state that representations received after the specified period are not accepted. 

What Can Be Challenged in the NDA 2 2026 Answer Key?

Candidates can raise a representation when they identify a genuine discrepancy in a question or the provisional answer.

Some possible grounds include:

The representation should focus on the specific question and the evidence supporting the objection, rather than simply stating that the answer appears wrong.

How to Challenge an NDA 2 Maths Answer?

For the Mathematics paper, candidates should first compare their booklet with the official UPSC provisional answer key.

If a question appears incorrect, check:

• The mathematical concept used
• Formula applied
• Calculation
• Given data
• Answer options
• Whether more than one option could be correct

The representation should clearly explain the mathematical basis of the objection and provide supporting evidence where required.

How to Challenge an NDA 2 GAT Answer?

For the General Ability Test, candidates should first identify whether the disputed question belongs to English or General Knowledge.

For a General Knowledge question, use authoritative sources such as government publications, official websites, or standard reference books wherever possible.

For an English question, provide a relevant grammatical or language reference supporting the proposed answer.

The stronger the documentary basis of the representation, the easier it is for the subject experts to examine the issue.

Is There a Fee for NDA 2 2026 Answer Key Objection?

Candidates should follow the instructions displayed on the official QPRep portal when submitting their representation. UPSC's published QPRep instructions focus on the online representation process and do not prescribe a separate objection fee in the general instructions. 

Candidates should rely on the instructions displayed on the official UPSC portal rather than information circulated through unofficial websites or social media.

Can You Send the NDA 2 Answer Key Objection by Email or Post?

Candidates should not rely on email, post, or offline submissions for raising a representation against the NDA 2 2026 question paper or provisional answer key.

The prescribed process is through the UPSC Online Question Paper Representation Portal (QPRep).

UPSC's QPRep system provides an online route for candidates to submit representations regarding questions and provisional answer keys. 

What Happens After You Submit the NDA 2 2026 Objection?

After representations are submitted, they are examined through the UPSC review process.

For the new provisional answer-key system, UPSC has stated that representations are placed before teams of subject experts for detailed examination. The experts review the representation and supporting material before arriving at their considered view on the disputed question or answer. 

Therefore, candidates should understand that submitting a representation does not automatically mean that the answer will be changed.

The final treatment of a disputed question depends on UPSC's review process.

Important Points Before Raising an NDA 2 2026 Answer-Key Objection

Candidates should keep these points in mind before submitting a representation:

NDA 2 2026 Answer Key: Check Your Answers Before Raising an Objection

The NDA 2 2026 Provisional Answer Key gives candidates an opportunity to compare their responses with the answers published by UPSC.

UPSC has released separate provisional answer keys for Mathematics and GAT. Candidates can use these keys to identify possible discrepancies before deciding whether a representation is required. 

Candidates can also compare the UPSC key with an unofficial answer key and detailed solutions from coaching institutes such as MKC. However, an unofficial answer key should be used only for comparison and analysis. Any formal representation against the UPSC provisional answer key should be submitted through the official UPSC process.
