A-Level Chemistry (9701) Grade Thresholds

The minimum marks Cambridge set for each grade in 19 AS & A Level Chemistry sessions from 2020 to 2026, taken from Cambridge's grade threshold table for each session. Every table is linked, so you can check any number against the source: from March 2022 the links go to Cambridge's own PDFs; for 2020 and 2021, which Cambridge no longer lists, to copies of the same tables.

Latest: June 2026

For the whole A Level sat in one series, an A* needed 201 to 219 out of 260 (77% to 84%) and an A needed 168 to 187 out of 260 (65% to 72%), depending on the option. At AS Level, grade a needed 79 to 95 out of 130 (61% to 73%).

Where each grade starts on one option: components 11, 21, 31, 41, 51, out of 260. Across all 7 options for the whole A Level sat in one series in June 2026, an A* needed 201 to 219.

How the A* threshold has moved

The mark needed for an A* on the whole A Level sat in one series, as a percentage of the maximum, in each session in our files. Where options differed, the bar runs from the lowest to the highest.

M = March, J = June, N = November. Sessions with no grade threshold table in our files are left out. Every number is in the table below.

How to read these tables

Your grade comes from your total mark across the papers you sat, after Cambridge's weighting. There is no A* on a single paper: Cambridge sets A* for the overall A Level only. Each option is one combination of papers, written as component codes: the first digit is the paper and the second is the variant, so 42 is Paper 4, Variant 2. Schools in different administrative zones sit different variants, which is why one session has several rows. Use the row with your components; your exams officer can tell you which ones you were entered for.

Each session's options fall into three groups. A Level, sat in one series is for candidates who sit all their A Level papers in the same series. AS Level is for the AS papers alone, graded a to e. Staged options are for candidates who carry forward their AS result from an earlier series to complete the A Level; their rows list the A Level papers, usually with an extra code that is not a 9701 paper (such as 85). A2-only options, also in that group, cover the A Level papers alone. Under each session below, the staged options are folded away; open them if that is your route.

Cambridge sets the thresholds after marking, aiming to keep each grade as hard to reach as it was the year before, so they move from session to session.

From 2026 Cambridge's tables list each combination of components without an option code, so the Option column shows a dash for those sessions.

Cambridge's tables up to March 2022 give the maximum marks once, in a sentence, rather than on each row: 260 for A Level and 130 for AS Level and for A2-only options. The "Out of" column for those sessions comes from that sentence. It gives no maximum for staged options that carry an AS result forward, so those rows show a dash.

Cambridge's tables also list a few options made only of components that are not 9701 papers (such as 50 and 60). They are left out here. The linked PDF always has the full table.

Frequently asked questions

How many marks do you need for an A* in A-Level Chemistry?

In June 2026, an A* needed 201 to 219 out of 260 (77% to 84%) for the whole A Level sat in one series, depending on the option (the combination of papers and variants) you were entered for. Across the 19 sessions on this page, that A* threshold ran from 62% to 84% of the marks, so it is worth checking the table for the session you are practising.

How many marks do you need for an a at AS Level Chemistry?

In June 2026, AS grade a needed 79 to 95 out of 130 (61% to 73%), depending on the option. AS Level is graded a to e.

What are the staged options in the 9701 tables?

Cambridge lets candidates carry forward their AS Level result from one series to complete the A Level in a later series. Staged options are the grade thresholds for that route, and A2-only options cover the A Level papers alone. Your exams officer can tell you which option you were entered for.

Where do these 9701 grade thresholds come from?

From Cambridge International's grade threshold table for each session, linked next to every session on this page. Cambridge publishes grade thresholds after each exam series on its grade threshold tables page.

Official source: Cambridge International AS & A Level grade threshold tables. If a number here ever differs from the table your school received, the school's copy is the one that counts, so ask your exams officer.
