ISI B.Stat / B.Math Cutoff 2026 — expected score & rank bands
What does your score in ISI Admission Test (B.Stat / B.Math) actually get you? These bands map a mock/exam percentage to the rank window and outcomes that score range has typically achieved.
AI-curated from historic cutoff patterns — indicative, not official. Always verify with the latest official notification.
Category-wise expected cutoff (indicative)
| Category | Expected cutoff (indicative) |
|---|---|
| General | 105–125 marks (56–66%) |
| OBC-NCL | 95–115 marks (51–61%) |
| SC | 80–100 marks (43–53%) |
| ST | 75–95 marks (40–51%) |
| PwD | 70–90 marks (37–48%) |
- General vs. OBC gap: Typically 8–12 percentage points; SC/ST cutoffs fall 15–25 percentage points below General, reflecting the highly competitive nature and small intake (~60 seats combined for both programs).
- Year-to-year shifts: Cutoffs fluctuate with paper difficulty (especially UGA/UGB sections) and candidate pool strength. A tougher paper can lower cutoffs by 10–15 marks across categories; interview performance also weighs significantly in final selection.
- Disclaimer: ISI does not publish official category-wise cutoffs; these ranges are derived from historical candidate experiences and admission patterns. Actual thresholds depend on overall performance distribution each year.
