Cambridge 9701 · grade thresholds

AS Chemistry 9701 grade boundaries

In May/June 2026, a grade A on Cambridge 9701 Paper 1 cost 30 marks on variant 14 but only 25 on variant 12 — a 5-mark difference on the same paper, in the same series. Thresholds are set after every series so that the standard stays constant while the papers vary, which means a harder paper gets a lower boundary. Variants are the same paper written for different exam zones, and your zone — not you — decides which one you sit.

Below is every series Cambridge has published for 9701 — 2023 to 2026, all three exam series — with each paper’s threshold and the overall syllabus thresholds beneath it. The numbers are Cambridge’s and every series links to the table they came from.

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. Paper 3, the practical, is marked out of 40 but counts as 30 towards the total, and the calculator applies that.

SeriesYour papers

Paper 11 / 40Paper 21 / 60Paper 31 / 40 · counts ×0.75Paper 41 / 100Paper 51 / 30

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 260:

A*	209 / 260 (80.4%)
A	185 / 260 (71.2%)
B	161 / 260 (61.9%)
C	133 / 260 (51.2%)
D	106 / 260 (40.8%)
E	79 / 260 (30.4%)

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 9701 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 23 9701 past papers, and each one shows its own threshold beside its topic breakdown.

Syllabus thresholds — the overall mark, after weighting, needed across a combination of papers. This is where A* exists. Which row applies to a student depends on which papers they were entered for.

Common questions

What do you need for an A* in A Level Chemistry 9701?

In May/June 2026, an A* needed 201 to 219 out of 260 overall — 77.3–84.2%, depending on which variants were sat (7 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 9701 grade boundaries for May/June 2026?

Every paper’s threshold for that series is in the table above. Paper 14 needed 30 of 40 for a A, and Paper 12 needed 25 of 40. 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 9701 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?

As one PDF per syllabus per series, free and without a login, on cambridgeinternational.org. Each series above links to the exact table its numbers were read from — the figures here are re-keyed facts, not a copy of Cambridge’s document.
