A case study answer needs a named place, specific detail nobody could invent, and a structure that separates causes, effects and responses. Most marks are lost not through weak knowledge but through unsorted knowledge — a page of facts about an earthquake with no organisation and no link to the question actually asked.
What examiners mean by a case study
Specifications distinguish two things, and the distinction is worth knowing.
- A named example is smaller: a specific place used to illustrate a process in a sentence or two. "Longshore drift has built Spurn Head on the Holderness coast."
- A case study is larger: a place studied in depth, where you can discuss causes, effects across categories, and responses over time.
Either way, the test is the same. Could your answer have been written by someone who had never studied that place? If the place name could be swapped for any other without changing a word, you have written a general answer with a label on it, and it will be marked as one.
The three things every case study answer needs
1. A named place, precisely located. Not "a country in Africa" but "Nigeria, in West Africa". Not "an earthquake in Asia" but naming the event and the year. Locational detail costs one clause and signals immediately that you studied something real.
2. Specific detail that could only be true of this place. Figures, dates, named schemes, named organisations, named landforms. You do not need dozens — three or four precise details, correctly used, beat a page of vague ones.
3. A structure that answers the question. This is the part students skip, and it is where most marks go.
The method, step by step
Step 1 — Read the command word and the categories
The command word tells you what kind of answer to write, and mark schemes are built around it.
| Command | What it wants |
|---|---|
| Describe | What it is like, or what the pattern shows — no reasons needed |
| Explain | Reasons and processes — the "because" |
| Assess / Evaluate | A judgement with evidence on more than one side |
| To what extent | A judgement with a clear degree — largely, partly, only in some respects |
| Discuss | Several viewpoints considered, then a conclusion |
Then check whether the question restricts you. "Explain the social effects" means environmental detail earns nothing, however good it is.
Step 2 — Plan in categories, not in memories
Do not write in the order you happen to recall things. Spend a minute sorting your material under headings.
For a hazard case study:
- Where and when, plus the physical cause
- Primary effects — immediate and direct
- Secondary effects — knock-on consequences
- Immediate responses — hours and days
- Long-term responses — months and years
For a human geography case study, sort effects three ways:
- Social — people, health, housing, education, community
- Economic — jobs, income, business, cost
- Environmental — air, water, land, wildlife
That three-way split is the single most useful habit in GCSE geography. It generates paragraphs automatically and stops you writing three versions of the same point.
Step 3 — Write one clear point per paragraph, then develop it
The reliable pattern is point, evidence, explanation, and — on higher-tariff questions — significance.
One major social effect was the loss of housing. In the Rio de Janeiro favelas, rapid unplanned growth left many families in self-built homes on steep, unstable slopes, so heavy rainfall causes landslides that destroy dwellings and displace residents. This matters because rebuilding on the same unstable land leaves the same population exposed to the next storm.
Three sentences, one point, developed. Compare a list of five effects with no development, which reads as knowledge without geography.
Step 4 — Use figures carefully, and never invent them
Precise data lifts an answer, but only if it is right. Use figures you are confident about, and where you are not, describe the scale honestly: "the majority of", "over half", "several thousand". An examiner accepts an accurate qualitative statement and is unimpressed by a confident wrong number.
Learn a small set of anchor facts per case study — the population, the year, one named scheme, one striking figure — rather than trying to memorise a table.
Step 5 — Cover both sides for assess and evaluate questions
If the command word asks for judgement, you must weigh. For a response or a management strategy, the natural axes are:
- Did it work for everyone, or only for some groups?
- Was it effective in the short term, the long term, or both?
- What did it cost, and who paid?
- Were there unintended consequences?
Sustainability questions have their own shape: a scheme is genuinely sustainable if it works socially, economically and environmentally. Pointing out that a project succeeds on two of the three and fails on the third is exactly the kind of evaluation the top bands are looking for.
Step 6 — Conclude with a judgement, not a summary
A conclusion that repeats your paragraphs adds nothing. A conclusion that decides, and says on what basis, adds a level.
Overall the scheme was effective in reducing flood risk for the town centre, since defences have held through subsequent high-flow events, but it was less successful environmentally, because hard engineering upstream has increased the discharge reaching communities downstream.
Step 7 — Watch the time
Work out roughly a minute per mark and hold to it. Case study questions carry high tariffs, so the temptation is to keep writing — but the marks come from structure and development, not from length, and time taken here is time stolen from something else on the paper.
Common mistakes
| Mistake | Fix |
|---|---|
| No named place at all | Name it in the first sentence, every time |
| Detail that fits anywhere | Add one fact that could only be true of this place |
| Effects and responses jumbled together | Sub-headings or clear signpost sentences in the plan |
| Answering the case study you revised, not the one asked | Re-read the question after every paragraph |
| Listing without developing | Fewer points, each taken further |
| Invented statistics | Describe the scale in words instead |
Frequently asked questions
How many case studies do I need to learn?
Follow your specification rather than a general number, since boards differ in how many they require and in whether the place is prescribed. As a rule, learn one solid case study per required topic and know it properly, rather than three you half-remember. What "properly" means is concrete: you can name and locate the place, give the cause, give effects in each of the social, economic and environmental categories, describe both immediate and long-term responses, and offer one clear judgement about how well those responses worked.
Can I use a different case study from the one my class studied?
Usually yes, unless your specification names a specific required example. Examiners are assessing whether you can apply geographical understanding to a real place, not whether you picked the same place as everyone else. The risk is that you know your alternative less thoroughly, and a well-chosen but thinly known example scores worse than the one you were actually taught. Check your specification for any named requirements before deciding, and if the exam question specifies a type of place — a lower-income country, a UK city — make sure yours genuinely qualifies.
What if I forget the figures in the exam?
Write the geography without them. A clear explanation of the process, using the correct terminology and a correctly named place, will earn most of the marks available; the statistic is supporting evidence, not the point. Describe the scale in words — "a large proportion of residents", "in the days following the event" — and press on. Inventing a number is the genuinely damaging option, because an examiner who spots one wrong figure begins to doubt everything else in the answer.
Do I need to memorise case studies word for word?
No, and trying to is counterproductive. A memorised paragraph tends to be reproduced whatever the question asks, which is precisely the failure mode examiners describe most often. Learn the structure — cause, effects by category, responses over time, judgement — plus a handful of anchor facts, and build the answer live from the question in front of you. Students who revise this way handle unfamiliar question wording far more comfortably than those who learned a script.
