AQA A-level Biology past papers and mark schemes
30 papers · June 2017 – June 2025
AQA A-level Biology (7402) is listed here as Paper 1, Paper 2 and Paper 3, under the codes 7402/1, 7402/2 and 7402/3. Each has 10 papers on this page, running from June 2017 to June 2025 across 9 exam series, with 3 specimen papers among them. All 30 come with a mark scheme. Paper 1 and Paper 2 are each worth 91 marks in 2 hours, while Paper 3 is worth 78 marks in 2 hours.
Most files come from AQA, the board that sets the papers, and some open on Physics & Maths Tutor. The list below is grouped by paper, then by series with the newest first, so you can find a particular sitting quickly. A sensible way to use them is to sit one under timed conditions, mark it honestly against the mark scheme and note the questions that cost you marks. You might begin with June 2017 and leave the most recent series until closer to your exams.
Reschedule is an A-level revision planner. You enter your subjects, exam board, the date of each paper and the hours you can study, and it builds a daily plan from the specification down to individual subtopics. Each subtopic lands before the paper that examines it, and past papers with mark schemes are added to the plan for each paper.
