Try 18 questions and three worked problems on moles, bonding, energetics and inorganic chemistry.

CH02 — Organic 1 and physical 1

Revise first-year organic chemistry, kinetics and K_c, including the epoxyethane reactions.

CH03 — Inorganic 2 and physical 2

Revise thermodynamics, cells, acids and inorganic chemistry, including Period 3 chlorides.

CH04 — Organic 2 and physical 2

Try 20 questions and four worked problems on rates, K_p and second-year organic chemistry.

CH05 — Practical and synoptic

Check the ten required practicals and try a question on evaluating results.

AS and the full A-level

CH01 and CH02 make up International AS. You can take AS on its own or count it towards the full International A-level. For the full A-level, you also need CH03, CH04 and CH05. AS assessments contribute 40% of the full qualification; the A2 assessments contribute 60%.

You can take units in January and May/June, and resit individual units while the specification is current. Your best result for each unit counts. Ask your centre about entries and certification if you’re resitting.

January 2027 chemistry exams

Check the official timetable and local starting time with your centre before making arrangements.

Using UK AQA papers

You can use UK AQA questions for many of the same topics, but you’ll need extra revision for epoxyethane, Period 3 chlorides and some aromatic reactions. The physical chemistry topics also sit in different units.
