Heaviest topic: Cell Structure, 175 marks across 175 questions.
| Topic | Questions | Marks |
|---|---|---|
| Cell Structure | 33 | 160 |
| Biological Molecules | 37 | 177 |
| Enzymes | 26 | 143 |
| Cell Membranes and Transport | 26 | 119 |
| The Mitotic Cell Cycle | 25 | 126 |
| Nucleic Acids and Protein Synthesis | 30 | 162 |
| Transport in Plants | 28 | 164 |
| Transport in Mammals | 34 | 226 |
| Gas Exchange | 23 | 99 |
| Infectious Diseases | 25 | 123 |
| Immunity | 29 | 181 |
Heaviest topic: Transport in Mammals, 226 marks across 34 questions.
| Topic | Questions | Marks |
|---|---|---|
| Energy and Respiration | 33 | 293 |
| Photosynthesis | 27 | 262 |
| Homeostasis | 38 | 368 |
| Control and Coordination | 44 | 347 |
| Inheritance | 52 | 413 |
| Selection and Evolution | 44 | 337 |
| Classification, Biodiversity and | 36 | 320 |
| Genetic Technology | 38 | 356 |
Heaviest topic: Inheritance, 413 marks across 52 questions.
Across every 9700 paper in these banks, the three heaviest topics are Inheritance (413 marks), Homeostasis (368 marks) and Genetic Technology (356 marks). The first of those alone is about 7% of every mark on offer. The lightest is Gas Exchange at 62 marks.
That matters because revising by whole past paper spreads your time evenly over topics the examiner does not weight evenly. Working topic by topic lets you spend the most time where the most marks are, and it shows you the handful of question shapes each topic actually uses rather than meeting one of them every few weeks.
Past papers are easiest to use when the questions are already sorted by topic, so you can finish one topic before starting the next instead of meeting it once every few papers. ExamYard prints the real Cambridge questions for AS Level Biology 9700 arranged that way, with the mark scheme kept separate from the question. Chapter 1 of every book is free to read, with no account and no email address.

The questions in these banks come from papers set between 2023 and 2026. Nothing older is included, because Cambridge changes syllabuses and older questions can test content that is no longer examined.
