A Level Biology Past Papers: Where to Find Them and How to Use Them
Where to find official A Level Biology past papers for AQA, Edexcel, OCR, Cambridge International and Edexcel International, how each board's exams are structured, and how to write answers that match the mark scheme.
Official A Level Biology past papers come from your exam board: AQA, Pearson Edexcel or OCR in the UK, and Cambridge International or Pearson Edexcel International at most international schools. Biology rewards precise answers on every board, and past papers are the best way to learn them. In 2026, just 27.4% of Biology results in England were A or A\* (tutor2u, 2026), against 34.6% for Cambridge International candidates (Cambridge International, 2026).
This guide shows where to find official papers for each board, how the exams are structured and how to use past papers to write answers that score.
Key Takeaways
- Use official papers and mark schemes from your own board and specification.
- Pearson Edexcel has two UK Biology specifications, so check which one you take.
- Mark schemes reward exact terminology, so learn the wording, not just the idea.
- Use examiner reports to see the mistakes most candidates make.
Where Can You Find Official Biology Past Papers?
Every board publishes papers free, with different rules. Pearson keeps papers from the most recent 12 months for teachers only (Pearson, 2026). AQA's summer 2026 papers reach its public website on 9 July 2027 (AQA, 2026).
| Board | Specification | Where to find papers | Access |
|---|---|---|---|
| AQA | Biology 7402 | AQA past papers | Public about a year after the exam |
| Pearson Edexcel (UK) | Biology A (Salters-Nuffield) 9BN0 or Biology B 9BI0 | Pearson past papers | Free, except papers from the last 12 months |
| OCR | Biology A H420 | OCR past paper finder | Public The newest papers may be restricted |
| Cambridge International | Biology 9700 | Cambridge 9700 past papers | Public selection Full archive for schools |
| Pearson Edexcel International | Biology YBI11 | Pearson past papers | Free, except papers from the last 12 months |
Cambridge's public 9700 page offers a selection of recent papers, mark schemes and examiner reports, with the full archive on the School Support Hub (Cambridge International, 2026). Edexcel's Biology A and Biology B are different courses, so don't mix their papers.
How Are AQA, Edexcel and OCR Biology Papers Structured?
UK A Level Biology is linear, with three papers at the end of Year 13. AQA's papers are 2 hours each, worth 91, 91 and 78 marks (AQA, 2026). AQA's Paper 3 includes an essay question, which needs its own practice.
| Board | Paper 1 | Paper 2 | Paper 3 |
|---|---|---|---|
| AQA (7402) | 2 hr, 91 marks (35%) | 2 hr, 91 marks (35%) | 2 hr, 78 marks (30%), including an essay |
| OCR (H420) | 2 hr 15 min | 2 hr 15 min | 1 hr 30 min: unified biology |
| Pearson Edexcel (9BN0 / 9BI0) | Three written papers on each specification Check your specification for timings |
Practical skills are assessed within these written papers, and in England a separate practical endorsement is reported alongside your grade.
How Are the Cambridge 9700 Biology Papers Structured?
Cambridge A Level Biology has five papers. Paper 4, the A Level structured paper, is worth 38.5% of the A Level, and the two practical skills papers together are worth 23% (Cambridge International, 2026).
| Paper | Time | Marks | Weighting |
|---|---|---|---|
| 1: Multiple Choice | 1 hr 15 min | 40 | 31% of AS / 15.5% of A Level |
| 2: AS Level Structured Questions | 1 hr 15 min | 60 | 46% of AS / 23% of A Level |
| 3: Advanced Practical Skills | 2 hr | 40 | 23% of AS / 11.5% of A Level |
| 4: A Level Structured Questions | 2 hr | 100 | 38.5% of A Level |
| 5: Planning, Analysis and Evaluation | 1 hr 15 min | 30 | 11.5% of A Level |
Paper 3 is a lab practical, often including microscope drawings, investigations and data handling. Paper 5 asks you to plan an investigation and analyse results, including statistics.
How Are Edexcel International Biology Papers Structured?
Pearson Edexcel International A Level Biology (YBI11) has six units. Units 1 and 2 are 1 hour 30 minutes and 80 marks; Units 4 and 5 are 1 hour 45 minutes and 90 marks; Units 3 and 6 are 50-mark written papers on practical skills.
The A\* needs an A overall plus at least 270 uniform marks on the A2 units (Pearson, 2026). See how A Level grades are calculated for how each board totals marks.
How Should You Use Biology Past Papers?
Use them as tests. A major review rated practice testing one of only two "high utility" learning methods (Dunlosky et al., 2013). In Biology, there's a second benefit: mark schemes show the exact wording examiners expect.
Mark strictly. Biology mark schemes on every board list specific points, and vague answers miss them. "The enzyme is destroyed" won't earn the mark that "the active site changes shape, so the substrate no longer fits" does. Build a list of the precise phrases that keep appearing in mark schemes, then use them in your own answers.
Command words matter more in Biology than many students expect. "Describe" a graph means quoting the trend with figures from the graph; "explain" means giving the biological reason. Many candidates explain when asked to describe, or describe when asked to explain, and lose most of the marks. Our A Level command words guide covers each word in detail.
When Should You Start Biology Past Papers?
Start with topic questions after each topic in Year 12, then move to full papers once the course is covered. Biology has a lot of content, so spacing your practice over many months works far better than cramming at the end (Dunlosky et al., 2013).
Save the most recent series for timed mocks in the final month. Our guide on how to revise for A Levels includes a month-by-month plan.
What Grade Can You Expect in A Level Biology?
Top grades in Biology are demanding. In England in 2026, 9.0% of Biology results were A\* and 27.4% were A or A\* (tutor2u, 2026). Among Cambridge International candidates, 13.7% got A\* and 34.6% got A or A\* (Cambridge International, 2026).
Boundaries vary too. In Cambridge's June 2026 series, an A on Paper 4 needed 60 out of 100 on variant 41 but 71 out of 100 on variant 42 (Cambridge International, 2026). On any board, grade a practice paper with the boundaries for that exact series.
Many of the Biology students we support are heading for medicine or life sciences. The biggest gains we see come from rewriting answers after marking: taking a 2-mark answer that scored 1 and rewriting it with the mark scheme's precise points. After a few weeks, students start writing that way first time. Our best A Levels for medicine guide explains why strong Biology grades matter.

Frequently Asked Questions
Where can I find AQA and Edexcel A Level Biology past papers?
On each board's website. AQA publishes papers about a year after the exam, and Pearson makes them free once they're more than 12 months old (AQA, 2026; Pearson, 2026). For Edexcel, check whether you take Biology A or Biology B.
Where can I find Cambridge 9700 Biology past papers?
Cambridge publishes a selection of recent 9700 papers, mark schemes and examiner reports on its public syllabus page. The full archive is on the School Support Hub for registered schools (Cambridge International, 2026).
Is A Level Biology harder than Chemistry?
They're hard in different ways. Biology has more content and demands precise wording; Chemistry is more conceptual and mathematical. In England in 2026, 27.4% of Biology results and 31.8% of Chemistry results were A or A\* (tutor2u, 2026).
How do I get better at Biology data questions?
Practise them from past papers, and always quote figures with units when describing data. On Cambridge, the planning, analysis and evaluation paper alone is worth 11.5% of the A Level (Cambridge International, 2026). Review examiner reports for common errors.
The Bottom Line
- Use official papers and mark schemes from your own board and specification.
- Learn the exact wording mark schemes reward.
- Match your answer to the command word: describe, explain or evaluate.
- Fewer than a third of Biology students in England got A or A\* in 2026.
