Marking Scheme
The marking scheme for the RRB Group D CBT is straightforward but has an important negative marking component that candidates must be aware of:
| Action | Marks | Details |
|---|---|---|
| Correct Answer | +1 | Full 1 mark awarded for each correct answer |
| Wrong Answer | -1/3 (0.33) | 1/3 of the marks allotted to that question is deducted |
| Unanswered | 0 | No marks awarded or deducted for unanswered questions |
Strategy Tip: With 1/3 negative marking, if you can eliminate even one option from a 4-option question, attempting it gives you a statistical advantage. If you can narrow down to 2 options, the expected value of attempting is positive. However, blind guessing across all 4 options has a negative expected value — avoid it.
Category-Wise Qualifying Marks
To be shortlisted for the Physical Efficiency Test (PET), candidates must score above the minimum qualifying percentage in the CBT. These are minimum qualifying marks, not cut-off marks — the actual cut-off is typically much higher.
| Category | Minimum Qualifying % | Marks (out of 100) |
|---|---|---|
| UR (Unreserved / General) | 40% | 40 |
| OBC-NCL (Non-Creamy Layer) | 30% | 30 |
| SC (Scheduled Caste) | 30% | 30 |
| ST (Scheduled Tribe) | 25% | 25 |
| EWS (Economically Weaker Section) | 40% | 40 |
Candidates who score above the minimum qualifying marks are ranked based on their normalised CBT scores. Those ranking within the shortlist (typically 3-4 times the number of vacancies) are called for the Physical Efficiency Test. For detailed cut-off analysis, visit our RRB Group D Cut-Off page.
