## Expected cutoffs (category-wise)
| Category | Expected Cutoff (Indicative) |
|----------|------------------------------|
| General | 87–90 marks (29–30%) |
| EWS | 78–81 marks (26–27%) |
| OBC-NCL | 75–78 marks (25–26%) |
| SC | 48–54 marks (16–18%) |
| ST | 42–48 marks (14–16%) |
| PwD (General) | 30–36 marks (10–12%) |
| PwD (OBC-NCL) | 27–33 marks (9–11%) |
| PwD (SC/ST) | 24–30 marks (8–10%) |

**Guidance:**
- The General-to-OBC gap typically ranges 12–15 marks (4–5 percentage points), while SC/ST cutoffs run approximately 45–50% of General cutoffs, reflecting reservation proportions.
- Cutoffs fluctuate year-to-year based on paper difficulty, number of shifts normalized, total applicants, and seat matrix changes; relatively easier papers push cutoffs up by 3–5 marks across categories.
- These are *qualifying* cutoffs for JEE Advanced eligibility; actual admission to specific IITs/NITs/IIITs depends on JEE Advanced rank (for IITs) or JoSAA/CSAB counseling ranks (for NITs/IIITs), where competition is substantially higher.
