WJEC A Level Biology past papers
30 WJEC A Level Biology papers from 2016 to 2025, 30 with a mark scheme. Every link opens the document on WJEC's own website; we list them in one place and show which topics each series tested.
Which topics come up most
The topics that have carried the most marks across the WJEC A Level Biology papers we have tagged question by question. Topics with a revision guide link to it.
| Topic | Questions | Marks | Papers |
|---|---|---|---|
| Organisms Respond to Changes in their Environments | 29 | 442 | 11 of 24 |
| Genetic Information, Variation and Relationships | 31 | 361 | 17 of 24 |
| Organisms Exchange Substances with their Environment | 30 | 359 | 9 of 24 |
| Genetics, Populations, Evolution and Ecosystems | 26 | 319 | 13 of 24 |
| Energy Transfers in and between Organisms | 19 | 276 | 9 of 24 |
| Cells | 20 | 261 | 10 of 24 |
| Biological Molecules | 22 | 256 | 8 of 24 |
| A-Level Biology: Required Practicals and Data Analysis | 11 | 183 | 8 of 24 |
| The Control of Gene Expression | 5 | 63 | 4 of 24 |
Counted from our own question-by-question tagging of 24 papers. A question that tests two topics counts towards both, so the marks column ranks topics rather than adding up to a paper total.
