RRB NTPC Answer Key 2025 — Full Details
RRB NTPC Answer Key
What is the RRB NTPC UG Exam & Answer Key
- RRB NTPC stands for Railway Recruitment Board Non-Technical Popular Categories. The “UG” or “Undergraduate” level refers to posts for candidates who have completed 12th grade (or equivalent).
- CBT-1 is the first computer-based test in the selection process. After CBT-1, candidates who clear it move on to further stages (CBT-2 etc.).
- The answer key is a set of correct answers (provisional) released by RRB, along with candidate response sheets and question papers. It allows candidates to cross-check their answers, calculate tentative scores, identify mistakes, and if necessary, raise objections to any incorrect answers before the final key is released.

How to Download NTPC UG Answer Key / View
You’ll typically follow these steps:
- Go to the RRB NTPC official portal (rrb.digialm.com) or the regional RRB site.
- Look for the notification titled something like “CEN-05/2024 (NTPC-Under Graduate) – Tentative CBT-1 Answer Key & Response Sheet”.
- Login using your registration number (or user ID) and date of birth / password as required.
- Once logged in, you should be able to view/download:
- The provisional answer key (shift-wise)
- Your response sheet (i.e. what you answered)
- The question paper for that shift.
What’s in the Answer Key / Response Sheet
- Correct answers for all questions in the exam.
- Your responses. Which ones you attempted, which ones left blank.
- Question IDs / Shift information. So you can match your test SHIFT with the relevant set of answers.
How to Calculate Your Estimated Score
- Each correct answer = +1 mark.
- Each wrong answer = – 1/3 mark (i.e. negative marking).
- Unattempted questions = 0 mark.
- Use your response sheet vs. answer key to count correct / wrong. Do the arithmetic accordingly to estimate your score.
Objection / Challenge Process
If you find an error in the provisional answer key (e.g., correct option seems wrong, or some ambiguity), RRB has provided a process:
- You can raise objections online through the official portal (Digialm, RRB site) within the specified window.
- There is an objection fee: ₹ 50 per question / answer challenged. If the objection is found valid, the fee is refunded.
- You may need to provide a valid reason / justification / proof/documentation for the objection.
Vacancies & Other Context
- Total undergraduate-level vacancies under this notification are 3,445 across various posts (Commercial cum Ticket Clerk, Accounts Clerk cum Typist, Junior Clerk cum Typist, Trains Clerk).
- The exam being “12th level / undergraduate level” means candidates applying for such posts need 12th pass or equivalent.
What Happens Next After Objection Window
- After the objection period ends, RRB will review all valid objections. If there are valid corrections, the final answer key will be published.
- Based on the final answer key, they will compute scores for all candidates.
- Then, the result for CBT-1 (Undergraduate) will be declared. Those who qualify move to CBT-2 (if applicable) or the next stage.
Why This Matters for You
- Helps you estimate your score ahead of result announcements so you know where you stand.
- You can see if you’re likely to qualify and start planning next steps (revision, preparation for next stage).
- If you believe some answer is wrong, raising objection gives you a chance to correct it — this ensures fairness and transparency.
Important Reminders / Tips for Candidates
- Always make sure you download / check the shift-wise answer key that corresponds to your exam shift. Using wrong shift can lead to wrong conclusions.
- Keep a record / screenshot / print of your responses, objection submission if you raise them (so in case of any dispute you have proof).
- Objections submitted after the deadline are usually not accepted, so don’t delay.
- Negative marking can significantly impact scores, especially if many guesses are wrong — be cautious when estimating.
- For any clarifications / updates (extension of objection window, changes, etc.), regularly check the official RRB / Digialm portal.

Expected Cut-Offs 2025 (Category-Wise)
| Category | Expected Cut-Off Range* (out of 100) |
|---|---|
| General / UR | 74 – 82 |
| OBC | 70 – 78 |
| EWS | 68 – 76 |
| SC | 62 – 70 |
| ST | 57 – 65 |
| Ex-Servicemen | 42 – 52 |
*These ranges are based on exam difficulty, previous trends, and expected competition. Actual cut-offs might differ slightly.
Basis / What These Estimates Assume
- Standard marking scheme: +1 for each correct answer, –⅓ for each incorrect answer.
- Exam held across many shifts, so there might be normalisation required (if difficulties vary between shifts) which could affect final cut-offs.
- Number of vacancies (3,445 for UG level posts) and high number of applicants increases competition, pushing cut-offs higher.
What You Should Aim For
To be safely above cut-off, depending on your category, here are target scores you might shoot for:
| Category | Safe Target Score |
|---|---|
| General / UR | ~ 80+ marks |
| OBC | ~ 75+ marks |
| EWS | ~ 72-75 marks |
| SC | ~ 65-68 marks |
| ST | ~ 60-63 marks |
| Ex-Servicemen | ~ 50+ marks |
