What is the RRB NTPC Marking Scheme?
By utilizing the RRB NTPC Undergraduate Level Answer Key 2026, candidates can estimate their total scores. To perform an accurate calculation, ensure you strictly follow the official marking scheme mandated by the board.
| Type of Answers | Marks Allotted |
| No. of Questions | 100 |
| Correct Answer | +1 |
| Wrong/Incorrect Answer | -⅓ mark |
| Blank Answer | 0 |
How to Calculate Marks Using the RRB NTPC Answer Key?
- For the correct answers, add one mark. If any answer is wrong, then deduct 1/3 marks
- Add all the marks for correct answers
- Add all the marks for incorrect answers
- In the end, deduct the total marks for correct answers from the incorrect answers. This will give a probable score.
Calculate your actual score based on attempted questions using the following formula:
{Raw Score} = {Total Correct} - {Total Incorrect X 1/3}
Calculation Example:
If you attempted 90 questions, with 72 correct and 18 incorrect answers, apply the formula to determine your final score.
- Positive Marks: 72
- Negative Marks: 18 X 0.33 = 6
- Raw Score: 72 - 6 = 66
RRB NTPC Minimum Qualifying Marks
Below are the minimum qualifying percentage marks required for eligibility across various reservation categories:
- UR – 40%
- EWS – 40%
- OBC (non-creamy layer) - 30%
