RRB Group D 2026 Answer Key: Expected Release Date, Objection Process & How to Calculate Marks

The RRB Group D 2026 Computer Based Test under CEN 09/2025 is currently underway, and candidates who have completed their examination are now waiting for the provisional answer key, response sheet and question paper.

According to the Railway Recruitment Boards' revised schedule, the Level-1 CBT is being conducted on 3–6, 9–14, 17–21 and 25 August 2026, covering a total of 16 examination days. Therefore, the examination process is not yet complete as of 21 August 2026, with the final scheduled CBT date being 25 August 2026.

RRB has not officially announced the CEN 09/2025 answer-key release date yet.

However, based on the immediately preceding Level-1 recruitment cycle, where the last CBT was held on 10 February 2026 and the provisional answer key was released on 17 February 2026, candidates can reasonably expect the Group D 2026 answer key within several days after the final CBT, potentially in late August or early September 2026. This is an estimate, not an official date.

Once released, candidates should be able to check:

This article explains the expected answer-key date, how to download it, how to challenge incorrect questions and how to calculate your expected RRB Group D marks.

The detailed CEN 09/2025 notification confirms 22,195 Level-1 vacancies, while the revised July 30 notice confirms the August CBT schedule.

Is RRB Group D 2026 Answer Key Released? No.

As of 21 August 2026, the provisional answer key for CEN 09/2025 Level-1 recruitment has not been released.

This is expected because the CBT itself is still in progress.

The revised official schedule includes one final examination date:

25 August 2026

Therefore, candidates should be cautious about websites or social-media posts claiming that the CEN 09/2025 answer key is already available.

RRB advises candidates to rely only on official Railway Recruitment Board websites for recruitment updates.

RRB Group D Answer Key 2026 Expected Release Date

RRB has not announced an official answer-key date.

But the previous Level-1 cycle provides a useful reference.

For CEN 08/2024:

Last CBT date:

10 February 2026

Provisional Answer Key:

17 February 2026 at 5:00 PM

That was approximately seven days after the final CBT.

The current CEN 09/2025 exam is scheduled to finish on:

25 August 2026

Therefore, if RRB follows a broadly similar timeline, the provisional answer key could reasonably appear around:

Late August to Early September 2026

A possible working expectation would be roughly:

26 August – 2 September 2026

but candidates should understand clearly:

This is an expected window, not an official RRB answer-key date.

Only a fresh RRB notice can confirm the exact date and time.

Why the Answer Key Usually Comes After All Exam Shifts

RRB Group D is being conducted on multiple dates and shifts.

Releasing the answer key before all scheduled CBTs are complete could create examination-security and fairness problems.

RRB therefore normally completes the examination process before opening the common facility for candidates to view:

Questions Responses Answer Keys Objection Tracker.

The previous Level-1 answer-key notice followed this same approach.

What Will RRB Group D Answer Key Show?

Once the provisional key is released, candidates can normally access a personalised response interface containing:

Question asked in your CBT Options shown in the exam Option selected by you Correct/provisional answer according to RRB Questions you did not attempt Objection facility for disputed questions/options/answers

This is much more useful than downloading an unofficial memory-based answer key because you can evaluate your actual recorded responses.

Provisional Answer Key vs Final Answer Key

Candidates should understand the difference.

Provisional Answer Key

This is the first official answer key released after the CBT.

Candidates are allowed to challenge questions or answers during a limited objection period.

Final Answer Key

After RRB examines valid objections, it decides whether any:

answer should be changed; question should be treated differently; objection should be rejected.

The final evaluation/result is then prepared according to the finalised key.

The previous Level-1 objection notice stated that the RRBs' decision on objections is final and binding.

How to Download RRB Group D Answer Key 2026

Once the official facility becomes active, candidates can follow these steps.

Step 1: Visit Your Official RRB Website

Open the official Railway Recruitment Board website relevant to your application.

Look for:

CEN 09/2025 – Level-1 Step 2: Find the Answer-Key Notice

Look for wording similar to:

“Viewing of CBT Questions, Responses & Answer Keys and Raising of Objections”

This is the wording RRB used for the immediately preceding Level-1 cycle.

Step 3: Open the Response/Answer-Key Link

Click the official candidate-login/objection-tracker link.

Step 4: Login

Use the credentials required by the portal, such as your:

registration details; date of birth/password; or other login information displayed by RRB.

The exact login fields should be confirmed when the CEN 09/2025 link becomes active.

Step 5: View Your Question Paper

Open your CBT question paper and recorded responses.

Step 6: Check the Provisional Correct Answers

Compare:

Your Answer

with:

RRB Provisional Answer. Step 7: Download or Save the Response Sheet

Save a copy while the facility is open.

Do not assume that the response-sheet link will remain available indefinitely.

RRB Group D 2026 Marking Scheme

The official CEN 09/2025 notification confirms:

Correct Answer +1 mark Wrong Answer −⅓ mark Unattempted Question 0 mark

RRB explicitly states that one-third mark will be deducted for each wrong answer.

RRB Group D Exam Pattern 2026

The official CBT structure is:

Subject Questions Marks General Science 25 25 Mathematics 25 25 General Intelligence & Reasoning 30 30 General Awareness & Current Affairs 20 20 Total 100 100 Exam Duration

90 minutes

Candidates eligible to use a scribe get 120 minutes.

RRB notes that the section-wise distribution is indicative and may vary somewhat in the actual question paper.

How to Calculate RRB Group D Marks

Use this formula:

Estimated Raw Marks = Correct Answers − (Wrong Answers ÷ 3)

Because:

each correct answer gives 1 mark; every wrong answer costs ⅓ mark; unattempted questions carry zero. Example 1

Suppose you have:

Correct Answers = 72 Wrong Answers = 18 Unattempted = 10

First calculate positive marks:

72 × 1 = 72

Negative marks:

18 × ⅓ = 6

Therefore:

72 − 6 = 66 marks

Your estimated raw score would be:

66/100 Example 2

Suppose:

Correct = 80 Wrong = 12 Unattempted = 8

Positive marks:

80

Negative marks:

12 ÷ 3 = 4

Expected raw score:

80 − 4 = 76 marks Example 3

Suppose:

Correct = 60 Wrong = 30 Unattempted = 10

Negative marks:

30 ÷ 3 = 10

Estimated score:

60 − 10 = 50 marks Quick Marks Calculation Table Correct Wrong Unattempted Estimated Raw Marks 85 10 5 81.67 80 15 5 75.00 75 15 10 70.00 70 20 10 63.33 65 25 10 56.67 60 30 10 50.00

These are raw-score calculations only.

Important: Raw Marks May Not Be Your Final Normalized Score

RRB Group D CBT is being conducted across multiple examination shifts.

The official notification states that:

Normalization of marks will be done for CBTs conducted in multiple shifts.

Therefore:

Answer-key calculation = estimated raw score

while

Result/score card = may contain normalized marks used for shortlisting.

Do not assume that a raw score such as 70.00 must appear exactly as 70.00 in the final result.

Why Does RRB Use Normalization?

Different shifts may contain slightly different sets of questions.

Even with a common syllabus, one shift could statistically be somewhat easier or harder than another.

Normalization is used to adjust scores across multi-shift examinations according to RRB's prescribed method.

So two candidates with similar raw marks in different shifts may not necessarily receive exactly identical normalized scores.

Minimum Qualifying Percentage

CEN 09/2025 specifies the following minimum percentages for shortlisting:

Category Minimum Percentage UR 40% EWS 40% OBC-NCL 30% SC 30% ST 30%

RRB may relax these percentages by 2 marks for PwBD candidates in case of a shortage against reserved PwBD vacancies.

Minimum Qualifying Marks Are NOT the Cut-Off

This distinction is extremely important.

Suppose you are an UR candidate.

The minimum qualifying percentage is:

40%

That does not mean a score of 40 guarantees PET selection.

Actual shortlisting will depend on:

number of vacancies; candidate performance; Railway/RRC; category; normalized marks; merit.

RRB states that candidates for PET will generally be shortlisted Railway/RRC-wise at three times the vacancies, though this ratio may be increased or decreased as required.

Therefore:

Qualifying Marks ≠ PET Cut-Off RRB Group D Objection Process 2026

The exact CEN 09/2025 objection notice has not yet been released.

However, the immediately preceding Level-1 cycle gives candidates a clear idea of how the process normally works.

For CEN 08/2024, candidates could challenge:

questions; options; provisional answer keys.

The objection process was conducted completely online.

Expected Steps to Raise an Objection

Once the CEN 09/2025 objection facility opens, the process is likely to be similar to this:

Step 1

Login to the official answer-key/response portal.

Step 2

Open the question you believe contains an error.

Step 3

Select the objection/challenge option.

Step 4

Choose the reason for the objection.

Step 5

Provide supporting details/evidence where the portal permits or requires it.

Step 6

Pay the applicable objection fee.

Step 7

Submit the objection before the deadline.

Step 8

Save the payment/submission acknowledgement.

The final CEN 09/2025 instructions should be followed once RRB publishes them.

RRB Group D Objection Fee 2026 The CEN 09/2025 fee has not yet been officially announced.

In the previous Level-1 cycle, RRB charged:

₹50 per question + applicable bank service charges

for raising an objection.

If an objection was found correct, the fee for that valid objection was refunded after deducting applicable bank charges.

The refund was made to the same account/payment source used to pay the objection fee.

For the 2026 CEN 09/2025 cycle, candidates should wait for the new objection notice before treating ₹50 as definitively confirmed.

Previous Group D Objection Window

For the previous Level-1 cycle:

Answer Key Opened

17 February 2026 at 5:00 PM

Objection Window Closed

23 February 2026 at 5:00 PM

Candidates therefore received approximately six days to view their responses and raise objections.

This does not guarantee that CEN 09/2025 will use the same number of days.

But candidates should expect the objection window to be limited and should review their response sheet promptly.

Which Questions Should You Challenge?

Do not challenge an answer merely because your answer differs from the provisional key.

A useful objection should generally have a clear reason, such as:

RRB's marked answer is factually incorrect More than one option is correct No option is correct Question contains a factual/technical error Translation changes the meaning of the question Correct answer is supported by an authoritative source

Avoid submitting objections based only on:

“My coaching centre says this option is correct.”

Use reliable supporting evidence wherever possible.

Can You Raise Objections After the Deadline?

Normally, no.

In the previous Level-1 cycle, RRB clearly stated that representations received after the prescribed closing time would not be entertained.

Therefore, do not wait until the final minutes of the objection window.

What Happens After Objections Are Submitted?

RRB subject experts examine the challenges.

Then one of several things can happen:

Objection Rejected

The provisional answer remains unchanged.

Objection Accepted

The answer may be corrected according to RRB's decision.

Other Appropriate Evaluation Decision

RRB may take an appropriate decision if it finds a problem with a question/options.

The final decision of RRB is binding under the objection process.

Will RRB Reply to Every Candidate Individually?

Candidates should not expect personal correspondence explaining each objection.

In the previous Level-1 notice, RRB clearly stated that its decision would be final and binding and that no further correspondence on the matter would be entertained.

What Happens After the Answer Key?

The expected recruitment sequence is:

CBT

↓

Provisional Answer Key + Response Sheet

↓

Objection Window

↓

Objection Review / Finalisation of Answers

↓

CBT Result + Cut-Off

↓

PET Shortlisting

↓

Physical Efficiency Test

↓

Document Verification

↓

Medical Examination

The official CEN 09/2025 notification lists the recruitment stages as:

CBT PET Document Verification Medical Examination. How Many Candidates Will Be Called for PET?

The notification states that candidates will generally be shortlisted:

Three times the community-wise total vacancies

Railway/RRC-wise for PET.

RRB retains the right to increase or decrease the ratio according to administrative requirements.

Since CEN 09/2025 has 22,195 vacancies, PET competition will depend heavily on Railway/RRC, category and normalized CBT merit—not only the national vacancy count.

Is PET Qualifying?

Yes.

The official notification says:

PET is mandatory and qualifying in nature.

Final consideration therefore requires both sufficient CBT merit and successful completion of the physical stage, subject to applicable exemptions.

How to Analyse Your Answer Key Properly

When the answer key arrives, do not simply count green and red responses.

Use this method.

Step 1 — Count Correct Answers

Write:

C = Correct

Step 2 — Count Wrong Answers

Write:

W = Wrong

Step 3 — Count Unattempted

Check:

C + W + Unattempted = Total Questions shown

Step 4 — Use the Formula Score = C − W/3 Step 5 — Check Disputed Questions Separately

Do not automatically change your score because you believe an answer key is wrong.

Calculate:

Score according to official provisional key

and separately note:

Possible score if your objection is accepted.

This gives a more realistic range.

Example With Objection

Suppose according to the provisional key:

Correct = 76 Wrong = 20 Unattempted = 4

Raw score:

76 − (20/3)

= 76 − 6.67

= 69.33

Now suppose you believe two of those wrong questions have incorrect official keys.

Do not immediately claim your score is 72+.

Your official provisional score remains approximately:

69.33

until RRB accepts the challenge.

Should You Compare Raw Marks With YouTube Cut-Off Predictions?

Be careful.

Immediately after the answer key, many websites and YouTube channels will publish:

“Safe Score” “Expected Cut-Off” “100% PET Rank”

These are estimates.

Official PET shortlisting depends on the actual:

normalized marks; category; Railway/RRC; vacancy position; number of candidates; final answer key.

Therefore, expected cut-offs can be useful as general analysis but should never be presented as confirmed selection.

CEN 08/2024 vs CEN 09/2025: Do Not Get Confused

There are currently two Level-1 cycles that candidates may see online.

CEN 08/2024

This is the previous Level-1 recruitment cycle.

Its:

CBT has finished; answer key was released on 17 February 2026; result was released on 1 July 2026; candidates were shortlisted for PET. CEN 09/2025

This is the current 22,195-vacancy Level-1 recruitment, whose CBT is being conducted in August 2026.

Its answer key:

Has NOT yet been released.

Do not accidentally open an old CEN 08/2024 answer-key link and think it belongs to the current recruitment.

RRB Group D 2026 Important Dates Event Date/Status CEN 09/2025 Detailed Notification January 2026 CBT Begins 3 August 2026 CBT Dates 3–6, 9–14, 17–21 & 25 August CBT Ends 25 August 2026 Provisional Answer Key Expected after CBT; date not announced Likely Answer-Key Window Late Aug / Early Sept — expected only Objection Window To be announced CBT Result To be announced PET To be announced

The CBT dates above are from the Railway Recruitment Boards' revised official schedule.

What Candidates Should Do Right Now

If your examination is already over:

1. Do not rely on memory-based answer keys as final.
2. Keep your registration details ready.
3. Monitor your official RRB portal.
4. Wait for the official response sheet.
5. Once released, download it immediately.
6. Calculate marks using the −⅓ rule.
7. Check questionable answers carefully.
8. Raise objections only with valid reasoning.
9. Save your response sheet and objection receipt.
10. Begin PET preparation instead of waiting for the result.

If your CBT is scheduled for 25 August, your priority should remain the examination rather than expected answer-key discussions.

12 Common Mistakes to Avoid

1. Saying the answer key is already out

It is not out for CEN 09/2025 as of 21 August 2026.

1. Confusing CEN 08/2024 with CEN 09/2025

The February answer key belongs to the older Level-1 recruitment.

1. Calling an expected answer-key date official

RRB has not announced one.

1. Forgetting negative marking

Every wrong response costs ⅓ mark.

1. Deducting marks for unattempted questions

Unattempted questions do not attract the wrong-answer penalty.

1. Treating raw marks as normalized marks

The CBT is multi-shift and RRB will normalize marks.

1. Treating minimum qualifying marks as cut-off

PET shortlisting will be merit-based.

1. Challenging every wrong answer

Challenge only when there is a legitimate issue.

1. Waiting until the last day to raise objections

The facility closes after a limited period.

1. Forgetting the challenge fee

The previous Level-1 cycle charged ₹50 + bank charges per question; wait for CEN 09/2025 confirmation.

1. Not saving the response sheet

Download it while the link remains active.

1. Waiting for the result before starting PET preparation

Candidates confident of competitive marks should start preparing for the physical stage early.

Frequently Asked Questions Is RRB Group D 2026 answer key released?

No. As of 21 August 2026, the CEN 09/2025 provisional answer key has not been released.

When will the RRB Group D answer key be released?

RRB has not announced an official date.

The final CBT is scheduled for 25 August 2026, so the answer key is expected after that date. Based on the previous Level-1 cycle, late August or early September is a reasonable estimate, but this is not official.

When does the RRB Group D exam end?

Under the revised schedule, the final examination date is:

25 August 2026. How many vacancies are there?

CEN 09/2025 contains:

22,195 Level-1 vacancies. How many questions are there?

The CBT has:

100 questions for 100 marks

with a normal duration of 90 minutes.

How much negative marking is there? ⅓ mark is deducted for every wrong answer. What is the formula to calculate Group D marks? Correct Answers − (Wrong Answers ÷ 3)

Example:

75 correct and 15 wrong:

75 − 5 = 70 marks

Is there negative marking for unattempted questions?

No. The penalty applies to wrong answers.

Will the calculated score be my final score?

Not necessarily.

Your calculation gives an estimated raw score. RRB states that normalization will be applied because the CBT is held in multiple shifts.

What is the objection fee?

The CEN 09/2025 objection fee is not yet confirmed.

For the immediately preceding Level-1 recruitment, RRB charged:

₹50 + applicable bank service charges per question. Is the objection fee refundable?

In the previous cycle, if an objection was found valid, the objection fee was refunded after deduction of applicable bank charges.

Candidates should check the new CEN 09/2025 notice for confirmation.

Can I challenge more than one question?

Normally candidates can challenge multiple questions, with the applicable fee charged per challenged question, subject to the rules in the new objection notice.

What happens after the objection window?

RRB reviews the objections, finalises the answers and later publishes the CBT result/shortlisting information.

What is the minimum qualifying percentage? UR — 40% EWS — 40% OBC-NCL — 30% SC — 30% ST — 30%.

These are minimum qualifying percentages—not guaranteed PET cut-offs.

Final Words

Candidates waiting for the RRB Group D 2026 Answer Key under CEN 09/2025 need to be careful with one important fact:

The answer key is NOT out yet.

The CBT is still ongoing, with examinations scheduled on:

3–6 August 9–14 August 17–21 August 25 August 2026.

RRB has not announced the official provisional-answer-key date.

However, the previous Level-1 cycle released its answer key seven days after the final CBT. Therefore, candidates can reasonably watch for the current key in late August or early September 2026, while treating any precise date as unofficial until RRB publishes a notice.

When the key is released, calculate your marks using:

Correct Answers − Wrong Answers ÷ 3

because the official marking scheme gives:

+1 for correct −⅓ for wrong.

But remember that this gives your raw estimated score. Since the examination is being conducted in multiple shifts, RRB will apply normalization while processing CBT performance.

Candidates should also use only the official CEN 09/2025 answer-key link. The answer key released on 17 February 2026 belongs to the older CEN 08/2024 recruitment, not the current 22,195-vacancy cycle.

Disclaimer: This article was updated on 21 August 2026 using the official CEN 09/2025 notification and Railway Recruitment Board CBT schedule. The CEN 09/2025 provisional-answer-key date and objection fee had not been officially announced at the time of writing. The estimated answer-key window is based on the previous RRB Level-1 cycle and should not be treated as a confirmed Railway notification.
