OJEE 2026 Answer Key Challenge: Dates, Process & Fee

The Odisha Joint Entrance Examination Board (OJEE) has opened the answer key challenge window for OJEE 2026. The provisional answer key and your response sheet will be available on your candidate login from May 14, 2026. You have until May 17, 2026 to challenge any answer you believe is incorrect. If your challenge is found valid by the expert committee, the answer key will be corrected and your ₹100 challenge fee will be refunded. This is your chance to ensure your score is calculated fairly — but you must provide solid proof from credible sources to support your objection.

What Is the Answer Key Challenge and Why It Matters

The OJEE 2026 answer key challenge is a formal process that allows you to dispute any answer in the provisional answer key if you believe it is wrong. This is not optional — it is a critical safeguard built into the exam system to ensure fairness and accuracy in scoring.

Why does this matter to you? Your final score depends entirely on the answer key used to mark your paper. If an answer in the key is incorrect and you caught it, challenging it could directly improve your score and your rank. Even if your own answer was wrong, a successful challenge corrects the key for all candidates, which is fair to everyone.

The OJEE committee will review every challenge you submit using subject experts. If your objection is found valid, the answer key is corrected, and the final merit list is recalculated. This is why the challenge window is so important — it is your only chance to flag errors before your score becomes final.

Important Dates: When to Challenge

The timeline for the answer key challenge is tight, so mark these dates clearly in your calendar.

The provisional answer key and your response sheet will be published on the OJEE candidate portal on May 14, 2026. You must log in with your application number and date of birth to access them. The objection window opens on the same day.

You have exactly four days — May 14 to May 17, 2026 — to review the answer key, identify errors, upload proof, pay the fee, and submit your challenges. After May 17, the portal will close and no further challenges will be accepted. Once the objection window closes, the OJEE committee will review all challenges and publish the final answer key.

• Provisional answer key and response sheet available: May 14, 2026
• Answer key objection period: May 14 to May 17, 2026 (4 days only)
• Final answer key published: After expert review (date not specified in notice)

Who Can Challenge and What You Need to Know

Any candidate who appeared for OJEE 2026 can challenge the answer key. You do not need special permission or eligibility — if you took the exam, you can raise an objection.

However, there are important rules. You can only challenge an answer if you have solid proof that it is wrong. Baseless objections — ones without supporting evidence — will not be accepted and your fee will not be refunded. The proof must come from a credible source, such as NCERT textbooks, official syllabus books, or other standard reference materials. Screenshots from websites, personal notes, or unverified sources will not be accepted.

You must also understand the question numbering and paper set you took before raising an objection. If you challenge the wrong question or misidentify the paper set, your objection will be rejected. Take time to carefully match the question ID in the portal with the question you want to challenge.

• You are eligible to challenge if you appeared for OJEE 2026
• You can challenge multiple questions, but each costs ₹100
• Proof must be from credible sources (NCERT, official syllabus, standard textbooks)
• Baseless objections without proof will be rejected and fee will not be refunded
• You must match the correct question ID before submitting

Challenge Fee: ₹100 Per Question (Refundable if Valid)

There is a non-refundable processing fee of ₹100 (one hundred rupees only) for each question you challenge. If you challenge 5 questions, you pay ₹500. This fee is charged to prevent frivolous objections and to cover the cost of expert review.

However, there is an important exception: if your challenge is found to be valid after thorough review by the OJEE committee, your ₹100 fee will be refunded. This means if you have genuine proof that an answer is wrong, you get your money back. Only candidates whose challenges are accepted receive refunds.

Payment is made online through the portal using credit card, debit card, net banking, or UPI. You must pay the fee before you can submit your challenge. The payment must be completed during the objection window (May 14–17, 2026).

• Challenge fee: ₹100 per question (non-refundable by default)
• Fee is refunded only if your challenge is found valid by the expert committee
• Payment methods: credit/debit card, net banking, UPI
• Payment must be made before submitting the challenge
• Multiple challenges = multiple fees (e.g., 3 questions = ₹300)

Step-by-Step: How to Challenge the Answer Key

Follow these 9 steps carefully to submit your challenge. Each step must be completed in order, and you must do everything within the May 14–17 window.

Steps 1–5 are about accessing the answer key and identifying errors. Steps 6–9 are about formally submitting your objection with proof and payment. Read through all steps before you start, so you know what documents you will need to upload.

• Step 1: Visit the official OJEE portal and look for the 'Challenge Answer Key OJEE 2026' link
• Step 2: Log in using your Application Number and Date of Birth (format: DDMMYYYY) or Password. This gives you access to your response, question paper, and provisional answer key
• Step 3: Go to the 'Candidate Response' tab to view questions and answers. Click on the 'Objection Form' tab and select your Subject/Course
• Step 4: View the questions, options, answers, and your attempted options on the same page
• Step 5: Cross-check your responses with the provisional answers. Mark any question where you believe the answer is incorrect
• Step 6: Select the question(s) you want to challenge. For each objection, choose the Question ID from the dropdown, select the Nature of Objection (e.g., 'Question is wrong', 'Incorrect Option', 'Multiple Options Correct'), and enter a clear justification in the Remarks field
• Step 7: Upload mandatory supporting documents (e.g., a page from a standard textbook) as PDF, JPG, or JPEG to prove your challenge
• Step 8: Pay the challenge fee of ₹100 per question online using credit/debit card, net banking, or UPI
• Step 9: Submit your challenge. The system will generate a confirmation receipt — save it for your records

What Proof You Must Upload (Critical Trap)

This is where many candidates fail. You MUST upload supporting documents to prove your challenge. Without proof, your objection will be rejected and you will lose your ₹100 fee.

The proof must be from a credible, standard source. Acceptable sources include: NCERT textbooks, official syllabus books, standard reference textbooks used in schools and colleges, and official government publications. Unacceptable sources include: personal notes, coaching materials, websites without official authority, screenshots from social media, YouTube videos, or any unverified source.

The document you upload must clearly show the correct answer or explanation. For example, if you are challenging a Biology question, upload a clear photo or scan of the relevant page from an NCERT Biology textbook that shows the correct answer. The uploaded file must be in PDF, JPG, or JPEG format only. Do not upload Word documents, images in other formats, or files larger than the portal's size limit (if specified).

⚠️ TRAP: If you upload proof from a non-credible source, or if the proof does not clearly support your objection, the expert committee will reject your challenge. You will lose your ₹100 fee and your score will not change. Spend time finding the right source before you upload.

• Proof is mandatory — no proof = automatic rejection and fee forfeited
• Acceptable sources: NCERT, official syllabus, standard textbooks, government publications
• Unacceptable sources: personal notes, coaching materials, websites, social media, YouTube
• Upload format: PDF, JPG, or JPEG only
• Proof must clearly show the correct answer or explanation
• The expert committee will verify your source — if it is not credible, your challenge is rejected

Types of Objections You Can Raise

When you submit a challenge, you must select the 'Nature of Objection' — the reason why you believe the answer is wrong. The portal gives you three options to choose from.

The first option is 'Question is wrong' — use this if you believe the question itself is unclear, ambiguous, or contains an error that makes it impossible to answer correctly. For example, if the question is missing information or has a typo that changes the meaning.

The second option is 'Incorrect Option' — use this if you believe the answer key has marked the wrong option as correct. For example, if the key says the answer is Option B, but you have proof that Option C is correct.

The third option is 'Multiple Options Correct' — use this if you believe more than one option is correct based on the question wording and standard references. For example, if both Option A and Option B can be justified as correct answers.

Choose the option that best describes your objection. Be specific in your Remarks field — explain exactly why you believe the answer is wrong and reference the proof you are uploading.

• Question is wrong: The question itself is unclear, ambiguous, or contains an error
• Incorrect Option: The answer key has marked the wrong option as correct
• Multiple Options Correct: More than one option is correct based on standard references

What Happens After You Submit: The Review Process

Once you submit your challenge by May 17, 2026, your work is done. The OJEE committee takes over from there.

After the objection window closes, the OJEE committee will review all submitted challenges. They will use subject experts — people with deep knowledge of the subject — to evaluate each objection. The experts will check your proof, verify whether your claim is valid, and decide whether the answer key should be corrected.

If your challenge is found valid, the answer key will be corrected for that question. The final answer key will then be published, and all scores will be recalculated using the corrected key. Your ₹100 fee will be refunded to your account. If your challenge is rejected, the answer key remains unchanged and your fee is not refunded.

The notice does not specify an exact date for when the final answer key will be published. It only says it will be published after the expert review is complete. Check the OJEE portal regularly after May 17 for updates.

• OJEE committee reviews all challenges after May 17, 2026
• Subject experts evaluate each objection using your proof
• If valid: answer key is corrected, scores are recalculated, your ₹100 fee is refunded
• If invalid: answer key remains unchanged, your fee is not refunded
• Final answer key is published after expert review (date TBD)
• Check the OJEE portal regularly for the final answer key

Common Mistakes That Get Your Challenge Rejected

Many candidates lose their ₹100 fee because they make preventable mistakes. Here are the most common ones — avoid them.

Mistake 1: Uploading proof from a non-credible source. If you upload a screenshot from a website, a coaching material, or a personal note, the expert committee will reject it immediately. Always use NCERT or official textbooks.

Mistake 2: Uploading proof that does not clearly support your objection. For example, uploading a page from a textbook that mentions the topic but does not show the correct answer. The proof must be specific and directly relevant to the question.

Mistake 3: Challenging the wrong question. If you select the wrong Question ID from the dropdown, your objection will be for a different question than the one you intended. Double-check the question ID before submitting.

Mistake 4: Not understanding the question numbering or paper set. If you took Paper Set A but challenge a question from Paper Set B, your objection will be rejected. Verify your paper set before challenging.

Mistake 5: Submitting a baseless objection without proof. If you submit an objection with no supporting document or with a document that does not prove your claim, it will be rejected.

Mistake 6: Missing the deadline. The objection window closes on May 17, 2026 at the end of the day. If you submit after this date, your challenge will not be accepted. Do not wait until the last minute.

Mistake 7: Not saving your confirmation receipt. After you submit, the system generates a receipt. Save this receipt — it is your proof that you submitted a challenge and can be used to follow up if there are issues.

• Do not upload proof from non-credible sources (websites, coaching materials, personal notes)
• Proof must clearly and directly support your objection
• Select the correct Question ID from the dropdown
• Verify your paper set before challenging
• Always upload supporting documents — no proof = automatic rejection
• Submit before May 17, 2026 — no late submissions accepted
• Save your confirmation receipt for your records

Important Tips Before You Challenge

Before you start challenging, take a moment to prepare. These tips will help you avoid mistakes and increase the chance that your challenges are accepted.

Tip 1: Always check the official OJEE announcement for the exact dates and times. The objection window is May 14–17, 2026, but always verify on the portal in case there are any last-minute changes.

Tip 2: Only challenge if you have a solid reason and valid proof. Do not challenge just because you are unsure about an answer. If you cannot find credible proof that the answer is wrong, do not waste your ₹100.

Tip 3: Keep your login details and application number handy. You will need them to access the portal. Write them down or save them in a secure place so you do not waste time searching for them during the objection window.

Tip 4: Check that the supporting references you provide are from credible sources. NCERT, official syllabus books, and standard textbooks are safe choices. If you are unsure whether a source is credible, do not use it.

Tip 5: Understand the question numbering and paper set properly before raising any objection. If you took Paper Set A, only challenge questions from Paper Set A. If you are unsure which paper set you took, check your admit card or the portal.

Tip 6: Review all your objections before submitting. Once you submit, you cannot edit or add more objections. Make sure you have challenged all the questions you want to challenge and that all your proof is uploaded correctly.

Tip 7: Do not challenge too many questions unless you have solid proof for each one. Submitting many weak objections will waste your money and damage your credibility with the expert committee.

• Verify the exact dates on the OJEE portal — objection window is May 14–17, 2026
• Only challenge if you have solid proof — do not waste ₹100 on weak objections
• Keep your application number and login details handy
• Use only credible sources (NCERT, official syllabus, standard textbooks)
• Verify your paper set before challenging
• Review all objections before submitting — you cannot edit after submission
• Do not challenge too many questions unless you have proof for each one

How This Affects Your Final Score and Merit List

The answer key challenge process directly affects your final score and rank. Here is how.

Your score is calculated by comparing your answers to the answer key. If the answer key is wrong, your score will be wrong. For example, if the key says the answer to Question 5 is Option B, but the correct answer is Option C, and you marked Option C, you will be marked wrong even though you are correct. By challenging and correcting the answer key, you ensure your score is calculated fairly.

Once the final answer key is published after all challenges are reviewed, all scores are recalculated using the corrected key. If your challenge was successful, your score may increase. If many candidates' challenges were successful, the merit list will be recalculated and ranks may change.

This is why the answer key challenge is so important — it is your last chance to ensure your score is accurate before the merit list is finalized and counselling begins. Do not skip this step if you believe an answer is wrong.

• Your score depends on the answer key used to mark your paper
• If the answer key is wrong, your score will be wrong
• Successful challenges result in answer key corrections
• All scores are recalculated using the final answer key
• The merit list is finalized based on the corrected scores
• This is your last chance to correct errors before counselling begins
