Q: What is IGCSE Biology Paper 5?
A: Paper 5 is the hands-on Cambridge IGCSE Biology Practical Test. Candidates carry out experiments in a lab, collect observations or measurements, present data, and evaluate the method.

Quick Paper 5 Map
| Read time | What to take away |
| 1 second | Paper 5 is the real lab version of IGCSE Biology practical assessment. |
| 10 seconds | You must handle apparatus, record observations, draw clearly, graph data, and evaluate the method. |
| 100 seconds | Prepare by practising common Biology contexts and the exam habits that make data easy to mark: neat tables, labelled drawings, sensible scales, and specific error comments. |
| Concrete example | In an osmosis task, record mass change in a clean table, plot the trend, then explain how concentration affected water movement. |
| Best next step | Check whether your exam centre offers Paper 5, then practise one full practical write-up under timed conditions. |

Private candidates in Singapore should confirm with their exam centre whether Paper 5 is available, because Paper 5 requires a centre with lab facilities. School candidates at international schools may sit Paper 5 if their school runs the practical test.
2 What Paper 5 tests
Paper 5 tests practical skill rather than long theory recall. Cambridge expects candidates to collect data, show observations clearly, analyse results, and evaluate the procedure.
The AO3 practical skills include:
- Selecting and safely using techniques, apparatus, and materials
- Planning experiments and investigations
- Making and evaluating observations, measurements, and estimates
- Interpreting and evaluating experimental observations and data
- Evaluating methods and suggesting improvements
3 Core Biology practical contexts
Microscopy and biological drawing
You may need to use a light microscope, observe a specimen, draw what you see, and label structures. Marks reward clean observation, not artistic shading.
Use:
- Single clear lines
- No sketchy outlines
- Labels with straight lines that do not cross
- Size and proportion that match the specimen
- Magnification or scale calculations when asked
Food tests
Food-test questions can involve Benedict's reagent, iodine, biuret reagent, and ethanol emulsion tests. The practical skill is remembering the reagent, the heating step where relevant, and the positive observation.
Write observations as actual colour changes, not vague words like "changed" or "reacted".
Osmosis and diffusion
Osmosis questions often use plant tissue, Visking tubing, or concentration series. The high-value marks are in controlling variables:
- Same initial size or mass of tissue
- Same volume of solution
- Same time in solution
- Same temperature
- Blotting method before measuring mass
Enzyme investigations
Enzyme contexts may vary temperature, pH, substrate concentration, or enzyme concentration. Record a clear dependent variable such as time taken, volume produced, or colour intensity.
Avoid a common mistake: changing more than one variable at once.
4 Paper 5 versus Paper 6
| Feature | Paper 5 Practical Test | Paper 6 Alternative to Practical |
| Lab apparatus | Used during the exam | Not used during the exam |
| Data | Collected by the candidate | Supplied in the question |
| Drawings | Drawn from real specimens | Drawn or interpreted from images or data |
| Evaluation | Based on the practical performed | Based on a described practical |
If you are preparing as a private candidate, use the IGCSE Biology Paper 6 guide. If your school enters you for Paper 5, train under real timed lab conditions.
5 Preparation plan
- Practise microscope setup and drawing weekly.
- Drill food-test reagent, method, and observation chains.
- Run one osmosis or enzyme data table every week and graph it by hand.
- Rewrite evaluation answers using the sequence: error, effect, improvement.
- Sit at least two timed Paper 5-style mock sessions before the exam.
