## Expected cutoffs (category-wise)
| Category | Expected Cutoff (Indicative) |
|----------|------------------------------|
| General | 68-75 marks out of 100 |
| EWS | 65-72 marks out of 100 |
| OBC | 63-70 marks out of 100 |
| SC | 55-62 marks out of 100 |
| ST | 50-58 marks out of 100 |
| PwD | 45-52 marks out of 100 |

**Guidance Notes:**

- **Category differential**: General cutoffs typically run 5-8 marks higher than OBC, 13-18 marks above SC, and 18-25 marks above ST categories, reflecting reservation policy implementation.

- **Year-on-year shifts**: Cutoffs fluctuate based on vacancy numbers (Bihar Police announces large recruitments periodically), paper difficulty (especially reasoning and general knowledge sections), and total applicant pool strength—easier papers push cutoffs 3-5 marks higher.

- **PwD consideration**: PwD cutoffs generally align 5-10 marks below the corresponding social category baseline; final selection depends on horizontal reservation availability and medical fitness clearance.
