SZF IOS · Estimate my score
We can't state one marking scheme for the SZF IOS paper
On our records +1 per question over 50 scored questions does not add up to the paper's 60 marks — different papers or sections of SZF IOS score differently.
On our records SZF IOS does not carry the same marks on every question — different papers or sections score differently, or not every question counts towards the total. A single calculator would hand you a wrong number, so we don't show one. Take the marking scheme from the official notice and count your marks against that.
Indicative cutoff (estimate, not official)
Indicative cutoff bands below are estimates from score bands, not official. The official cutoff comes with the result.
| Category | Expected cutoff (indicative) |
|---|---|
| General | 46-50 / 60 (76-83%) |
| EWS | 44-48 / 60 (73-80%) |
| OBC | 43-47 / 60 (71-78%) |
| SC | 40-44 / 60 (66-73%) |
| ST | 38-42 / 60 (63-70%) |
| PwD | 36-40 / 60 (60-66%) |
- Category differential: General-to-OBC gap typically 5-8%, OBC-to-SC another 5-7%, reflecting reservation norms. PwD cutoffs align near SC/ST thresholds with slight relaxation.
- Cutoff drivers: Annual cutoffs shift based on paper difficulty, participation volume, and performance distribution. Science Olympiads see tighter clustering at mid-high scores; a 3-5 mark swing can significantly alter rank brackets.
- Achievement context: These cutoffs target State/Regional Rank Holder tier (76-85% band). Elite performers (93%+) transcend category distinctions; cutoffs matter most for zonal/school-level recognition certificates.
