Q: What is CIE Biology Paper 5?
A: Paper 5 is the written Planning, Analysis and Evaluation paper for Cambridge International A Level Biology 9700. It tests AO3 practical reasoning without requiring lab work during the paper.
TL;DR
Biology 9700 Paper 5 lasts 1 hour 15 minutes, carries 30 marks, and contributes 11.5% of A Level. It tests planning, analysis, and evaluation. Biology candidates should expect experimental design, variables, reliability, graphs, statistical reasoning, and conclusions from unfamiliar biological contexts.
Quick written-practical route
| If you have... | Focus on... |
| 1 second | Paper 5 is practical reasoning on paper |
| 10 seconds | Variables, graphs, reliability, and evaluation |
| 100 seconds | Practise writing one plan with a clear control and repeat strategy |
Concrete example: a stronger evaluation point
Weak: "Do more repeats." Stronger: "Use at least five samples per treatment because individual organisms vary." The second answer names the biological reason and the improvement.

Paper 5 is not a theory essay paper. Cambridge can set unfamiliar biological contexts, then assess whether you can plan and evaluate scientifically.
2 Planning marks
Planning answers usually need:
- Independent variable and range
- Dependent variable and measurement method
- Controlled variables and how they are controlled
- Repeat strategy
- Safety or ethical considerations where relevant
- Data processing plan
In Biology, always specify how biological variation is controlled or sampled.
3 Analysis marks
Biology analysis often asks you to process data, interpret a graph, compare treatments, or decide whether a result supports a hypothesis.
Score by quoting values and using careful comparative language. Avoid saying "proves"; write that the data supports or does not support the hypothesis.
4 Evaluation marks
Strong evaluation links the limitation to the biological system:
- Individual organisms vary, so sample size matters.
- Colour-change endpoints can be subjective.
- Temperature affects enzyme activity and diffusion rate.
- Sampling bias affects ecological conclusions.
Pair each limitation with a realistic improvement.
