ZIO cutoff: expected score and rank bands
No official ZIO cutoff is published on Shishya yet — the score bands below are indicative, not official. Official cutoffs are published at iarcs.org.in.
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 | 55–65 marks out of 100 |
| EWS | 50–60 marks out of 100 |
| OBC | 48–58 marks out of 100 |
| SC | 40–50 marks out of 100 |
| ST | 38–48 marks out of 100 |
| PwD | 35–45 marks out of 100 |
- ZIO historically maintains a General category cutoff in the 55–65 range for INOI qualification; OBC typically receives a 5–8 mark relaxation, SC/ST enjoy 10–18 mark concessions to broaden access to national-level training.
- Year-to-year shifts depend on problem difficulty (particularly algorithmic complexity), overall candidature strength, and IARCS policy on cohort size for INOI; a harder paper may depress cutoffs by 5–10 marks across all categories.
- Top performers (82+ marks) across all categories secure direct IOI training camp selection; the cutoff primarily governs the threshold for INOI eligibility, not excellence recognition.
