IGCSE Maths 0580 Grade Boundaries: A* to G

What do you need for each grade?

Pick a series and the papers you are entered for, type the marks you have or expect, and leave one paper blank: the calculator shows what that paper needs for each grade.

SeriesYour papers

Paper 11 / 80Paper 31 / 80

Enter the marks you have or expect on every paper but one, and this shows what the last one needs. The May/June 2026 thresholds for these papers, out of 160:

C	82 / 160 (51.3%)
D	68 / 160 (42.5%)
E	55 / 160 (34.4%)
F	42 / 160 (26.3%)
G	29 / 160 (18.1%)

Thresholds move every series, so this is an estimate for yours, not a promise. Cambridge’s May/June 2026 table

Component and syllabus thresholds are different numbers

Almost every page that quotes “the 0580 grade boundaries” is quoting one of two different things, so it is worth separating them:

A component threshold is the raw mark one paper needed. Cambridge states that grade A* does not exist at the level of an individual component — so if you see an A* against a single paper anywhere, it is invented.
A syllabus threshold is the total across a combination of papers, after weighting, and it is the grade that appears on the certificate. A* exists only here.

The combinations matter more than students expect. Cambridge offers several entry routes, each a different set of papers with its own maximum and its own thresholds — which is why two candidates with the same raw total can be awarded different grades. Quanta has broken down 42 0580 past papers, and each one shows its own threshold beside its topic breakdown.

Common questions

What do you need for an A* in IGCSE Maths 0580?

In May/June 2026, an A* needed 162 to 177 out of 200 overall — 81–88.5%, depending on which variants were sat (3 combinations of papers). A* is awarded only on that overall total; no single paper has an A* threshold. The calculator above shows what you need on a paper you haven’t sat yet.

What were the 0580 grade boundaries for May/June 2026?

Every paper’s threshold for that series is in the table above. Paper 42 needed 79 of 100 for a A, and Paper 21 needed 64 of 100. The overall syllabus thresholds, which are the ones that decide the grade on your certificate, are listed beneath them.

Why do grade boundaries change every series?

Because the papers differ slightly in difficulty and the standard must not. Cambridge sets thresholds after marking, so a harder paper gets a lower boundary and a candidate is not penalised for which version they sat. It also means last year’s boundary is a guide, never a promise.

Is there an A* for a single 0580 paper?

No. Cambridge’s own tables say grade A* does not exist at the level of an individual component. A* is set only on the overall syllabus thresholds, across the combination of papers you were entered for.

Where does Cambridge publish these?
