Exam requirements and worked examples
Match your writing to the component
The 70-mark Written Exam has four compulsory questions using supplied sources. Depending on the question, you may identify an argument, assess the quality of evidence or recommend a course of action with reasons. Answer the precise instruction. Explaining a weakness in a source takes more than identifying that weakness. Show what the weakness means for the claim you are asked to examine.
For the 60-mark Individual Report, choose a question linked to a listed topic, use it as your title, and write in continuous prose. Explore a global perspective and one or more local or national perspectives. Analyse causes and consequences, consider possible actions, propose one and reflect on your own view. Cite the sources you use. The bibliography or reference list is excluded from the report word count.
The 70-mark Team Project has a shared element and an individual one. The team produces a 300–400-word Explanation of Research and Planning and submits Evidence of Action. Each student writes a 750–1,000-word Reflective Paper about research, contribution and learning. The Reflective Paper is a separate task. Explain your own role and evaluate what the team did using specific observations.

Worked example about reducing food waste
Try this original question. When should schools use advance meal ordering to reduce food waste? Imagine one school tracks the number of unsold portions before and after an ordering trial. A separate pupil survey says some students miss the deadline because they decide what to eat later. The first source helps measure unsold stock. The second raises a concern about access. Both can be useful even if they answer different parts of the question.
Evaluate how the sources were made. Unsold portions count food prepared but never served. They may miss food left on trays. A voluntary survey may overrepresent students who felt strongly about the new system. Explain the effect of each limit. If the question concerns all food waste, measuring only unsold portions narrows the conclusion. If the question concerns whether all students can get lunch, the survey can identify a possible problem without establishing how common it is.
A possible course of action is to use advance orders and keep a limited supply for pupils who miss the deadline. A school could compare unsold portions, tray waste and access across similar weeks. In a real report, support the proposal with evidence from relevant contexts and explain why a different approach would be less suitable. The practice data here are invented.
Fencing Method for evidence and evaluation
Start with The source is limited. Add detail. The source counts unsold portions at one school. Refine the tone. The count is useful for estimating unsold stock at that school. Add logic. Because it does not include food left on trays, it gives only a partial measure of overall waste. Transfer the pattern by evaluating a transport survey that covers just one route.
Next fence perspective. Name the person or group, its concern and the reason the concern matters. School staff may prioritise predictable orders. Pupils may value flexibility or access. Compare those positions around one decision. Once the reasons are visible, you can judge whether a suggested action addresses both or requires a trade-off.
Compare perspectives on a common issue
Create two note columns with the headings claim, reason, evidence and priority. Fill them in from sources that discuss the same issue. If one source wants to reduce costs and another wants to maintain access, explain why both priorities affect the decision. Then check whether the apparent disagreement is about what the policy achieves or about what counts as success.
Connect the local and wider evidence carefully. A national study might show how widespread a problem is, while a school record can explain a local pattern. Use the sources together by giving each one a clear job. When you move a proposed solution from one place to another, name one condition that must be similar for the approach to work.
Write reflection that shows a change in thinking
Start with what you assumed before the research. Name a specific source or experience that made you reconsider it. Then explain what you think now and what further evidence would help. For example, a team might discover that its waste measures missed tray leftovers and revise the monitoring plan. That decision is evidence of learning because it explains what changed and why.
For teamwork, identify one task you did, how it helped the project and what you would change next time. A brief account of a difficulty can work well when it explains how the team responded. Link the reflection to what you learned about the issue, the method or collaboration.
Frequently asked questions
Can I use the same source twice? Yes, if it supports two different claims and you explain each use. Do different perspectives have to oppose each other? Cambridge asks for clearly different perspectives, which can overlap. Should my report end with an action? Explain the proposed action as part of the analysis and finish by answering your research question.
Make a three-sentence source test
Write one sentence stating what the source claims, a second explaining its strongest piece of evidence and a third assessing a limit. Check whether the third sentence changes the strength or scope of the claim. If your assessment could be pasted next to any source, replace it with a detail about the sample, method, date or context.
Turn a broad issue into a research question
Write the broad topic, the people affected and the outcome you want to investigate. Then choose a single question that can be explored using sources at different scales. Ask a classmate what evidence would count as an answer. If they name several unrelated outcomes, tighten the wording. A focused question gives the report enough room to compare perspectives, evaluate evidence and explain why one course of action is appropriate.
