HOW IT WORKS
How the Grade Checker Works
Built around the Cambridge 0580 (2025–2027) paper structure and recent grade boundaries.
1. Add Up Your Papers
Core students add Paper 1 (/80) and Paper 3 (/80) for a total out of 160. Extended students add Paper 2 (/100) and Paper 4 (/100) for a total out of 200.
2. Compare to Boundaries
Your combined mark is compared to the typical grade boundaries for each grade. The highest grade your mark reaches is your likely grade.
3. See the Gap
The checker shows how many marks separate you from the next grade up — often just a few marks per paper, which is very achievable with focused practice.
4. Indicative Only
Cambridge sets official boundaries after each session based on paper difficulty, so treat this as a guide rather than a guarantee.
Indicative Grade Boundaries — Cambridge IGCSE Maths 0580
Core is marked out of 160 (Paper 1 + Paper 3, 80 each); Extended out of 200 (Paper 2 + Paper 4, 100 each). Minimum combined marks typically needed for each grade:
| Core (Papers 1 & 3) | Min marks (of 160) |
|---|---|
| Grade C | 100 |
| Grade D | 75 |
| Grade E | 58 |
| Grade F | 45 |
| Grade G | 35 |
| Extended (Papers 2 & 4) | Min marks (of 200) |
|---|---|
| Grade A* | 170 |
| Grade A | 150 |
| Grade B | 125 |
| Grade C | 95 |
| Grade D | 70 |
| Grade E | 50 |
These grade boundaries are indicative only. Cambridge sets the official boundaries after each exam session based on how difficult that session's papers were, so they shift from one series to the next. Use this checker as a guide to roughly where a mark might land, not as a guarantee of a grade.
