“Knowing what a case decided and knowing when to cite it are two different skills, and only one of them is worth marks.”
Law revision has a specific way of feeling more finished than it is. You read through a case summary, the facts make sense, the ratio is clear, and you move on knowing that case. Then a problem question hands you a completely different set of facts and asks whether the same principle applies, and the confident feeling doesn't transfer nearly as cleanly as it seemed like it would.
That gap is the entire skill law exams are testing, and it's easy to revise around it without noticing.
Why "I know the case" isn't the same as being ready
A law exam essay or problem question rarely asks you to just state what a case decided. It gives you a new scenario and asks whether the principle from that case applies, and if so how, and if not why not. That's a different skill from recall: it's application, and it's the one thing rereading a case summary never actually practises.
Knowing Donoghue v Stevenson established a duty of care is recall. Recognising that a new set of facts about a faulty product raises the same question, and being able to argue whether the duty extends to this situation, is application. Most revision time goes toward the first one because it's what a textbook gives you. Exams are built around the second.
What actually builds the right skill
Work through problem questions with new facts, not the facts from your notes. Take a case you know well and invent a variation, a different product, a different relationship between the parties, a fact that's just different enough to raise the question of whether the principle still applies. Argue it both ways. This is the actual exam skill, and reading case summaries never practises it.
Build your own case list from memory, then check it. For a given area of law, close your notes and write out every case you can remember that's relevant, with what each one actually decided in one sentence. What you can't produce cold is what you don't actually have yet, even if it looked familiar five minutes ago while you were reading it.
Practise distinguishing, not just citing. A strong answer often depends on arguing why a case does or doesn't apply to the facts in front of you, not just naming it. Take two similar-sounding cases and write out, from memory, what actually separates them. If you can't say what's different, you can't use them against each other in an argument, which is often exactly what a strong essay needs to do.
Statutes: know the actual wording of the key sections, not just the gist. A problem question often turns on specific statutory language, and "the general idea" of a section isn't the same as being able to apply its actual wording to the facts you've been given. Where a statute matters, learn the section number and the operative words, not just the topic it covers.
Structure the answer before you write it, every time you practise. IRAC, or whatever structure your course uses (issue, rule, application, conclusion), only helps if it's automatic under time pressure. Practising it only in an untimed, relaxed way means the first time you do it under real exam conditions is the exam itself.
A revision rhythm built around application
- Learn a topic once: read the cases and the rule, then immediately try applying it to one invented scenario before moving on, rather than trusting that reading it once means you can use it.
- A few days later: a new problem question on the same area, closed-book, full structure, checked against a model answer or examiner's report if your course has one.
- Cross-topic practice closer to the exam: a scenario that could plausibly raise issues from two different areas at once, since real exam questions often do this and pure single-topic practice doesn't prepare you for spotting it.
- The final stretch: the cases and distinctions you keep forgetting or misapplying, not a full reread of everything.
The short version
A case summary you can recognise is not the same as a principle you can apply to facts you've never seen, and that gap is exactly what law exams are built to test. Practise with invented facts, build your case list from memory instead of rereading it, learn to distinguish cases rather than just cite them, and structure your answers under real time pressure before the exam is the first time you try it. That's the actual skill, and it's not the one a case summary teaches you on its own.
