## Expected cutoffs (category-wise)
| Category | Expected Cutoff (indicative) |
|----------|------------------------------|
| General | 46-50 / 60 (77-83%) |
| EWS | 44-48 / 60 (73-80%) |
| OBC | 43-47 / 60 (72-78%) |
| SC | 40-44 / 60 (67-73%) |
| ST | 38-42 / 60 (63-70%) |

**Guidance:**

- SOF IMO does not officially implement category-based reservations; the above ranges reflect typical score distributions where SC/ST/OBC students may qualify for recognition awards at slightly lower absolute scores due to internal school/state ranking mechanisms and participation patterns.

- General-vs-OBC differential is modest (4-5 marks), as the exam rewards conceptual strength universally; year-to-year shifts of ±2-3 marks occur based on paper difficulty and the cohort's performance distribution.

- Cutoffs for medals/recognition certificates vary by class level and regional participation density; achieving 76%+ consistently places students in state-level excellence brackets across all backgrounds.
