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.

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.
