How to study law: cases, statutes and exams

What law exams actually test

Law exams come in a few forms: problem questions (a set of facts, and “advise the parties”), essays on a doctrine or a debate, multiple-choice questions in some bar exams, and oral exams, common in many civil-law countries. Under the forms, they test the same two abilities.

• Knowing the law exactly: the rule, its elements, the exceptions, the leading cases or the relevant articles, and the tests courts use.
• Applying it: spotting which issues the facts raise, choosing the right rules, and reasoning through them to a conclusion, under time pressure.

Students who only read and summarise often know the law in outline but can't produce the precise rule when they need it. Students who only memorise can recite rules but miss the issues hidden in a problem. A good method trains both.

Common law and civil law: one method, different sources

In common-law systems, such as England and Wales, Ireland and the United States, much of the law lives in cases: you learn the rule a case stands for (its ratio decidendi) and how later courts applied or distinguished it. In civil-law systems, such as most of continental Europe, the core is the codes: you learn the structure of the code, what each key article requires, and how courts and scholars interpret it. EU law mixes treaties, legislation and the case law of the Court of Justice.

The method below works for all of them. What changes is what goes on your cards: case names and holdings in one, articles and their conditions in the other. Some exams, such as Germany's state exams, let you bring the code itself; then learn where things are and how to apply them, not the wording.

Reading cases without drowning in them

A judgment can run to dozens of pages, and most of it won't be examined. Read with a purpose and write a short brief:

1. The facts, in two or three lines: only the ones that mattered to the outcome.
2. The issue: the legal question the court had to answer.
3. The holding or ratio: the rule the case stands for, in one sentence.
4. The reasoning: why the court decided as it did, including any policy arguments.
5. Why it's on your syllabus: what it established, changed or illustrates.

Read your course materials' extracts first, and the full judgment only for the leading cases. The brief, not the story, is what you'll turn into cards.

Reading statutes and codes

• Start with the structure: which book, title and chapter deal with the topic, and where the general rules sit relative to the special ones.
• Read the definitions first. Many provisions only make sense once you know exactly what a defined term covers.
• Break each key provision into its conditions (what must be true) and its consequence (what follows).
• Note the exceptions and cross-references, and where courts have filled gaps.
• Learn article numbers only where your exam expects you to cite them.

Build your own outline

An outline (or a structured summary) organises a subject the way an exam answer needs it: topic, rule, elements, authorities, exceptions, and the arguments on each side. Making it yourself is part of the learning, because you decide how the pieces fit together. Commercial outlines are useful for checking yours, not for replacing it.

Keep it short and structured, and revise it as the course goes on. Then use it as the source for two kinds of practice: flashcards for the rules, and problem questions for applying them.

Memorising rules with active recall

Reading your outline again and again feels like revision but builds familiarity, not recall. Testing yourself on it is what makes rules available in an exam: see active recall. For law, these kinds of cards work best:

Rules as elements

Learn each rule as a short list of elements, because that's how you'll apply it: one paragraph per element in an exam answer. A card that asks for the elements is good; separate cards for each element's test are better.

An example and a counterexample

For each important rule, learn one case or scenario where it applies and one where it doesn't. This is what turns a rule you can recite into a rule you can use, and it's where most marks are won or lost.

Cloze cards for exact wording

Where the wording itself matters, such as a statutory definition, use fill-in-the-blank cards and keep the blank to the word or phrase that carries the meaning.

Application: practise problem questions

Knowing the rules gets you half the marks. The other half comes from applying them, and that needs practice in the form the exam uses.

1. Learn a structure for answers. Many students use IRAC: Issue, Rule, Application, Conclusion. Use your faculty's preferred structure if it has one.
2. Make an issue checklist for each topic from your outline: the questions to ask of any set of facts.
3. Answer past problem questions, closed-book and timed, then compare with model answers or your tutor's feedback.
4. List the issues you missed and the rules you stated imprecisely. Each becomes a card or a fix in your outline.
5. Repeat with mixed topics: exams combine several areas in one problem.

Spacing it over the semester

Law courses are long and cumulative, and the exam comes at the end. Reviewing a little of everything every week, rather than one topic at a time before the exam, uses the spacing effect: the same study time, spread out, is remembered far longer. A spaced repetition app schedules your cards so that you see each rule just before you'd forget it. See cramming vs spaced repetition.

Mixing topics in a session (interleaving) also helps you tell similar doctrines apart, which is exactly what issue spotting requires. Reviewing a deck with cards from several topics does this for you.

Studying with others

Law suits group study better than most subjects, if the group practises rather than rereads. Write hypotheticals for each other, argue both sides of a problem, and explain a doctrine to someone who missed the class. Explaining without notes is retrieval practice and self-explanation at once.

A weekly routine

The exam run-up

1. Four weeks out: finish the outline and the cards for every topic, and give the course its exam date so reviews are timed for it.
2. Then: a timed problem question most days, mixing topics, plus daily reviews.
3. Two weeks out: condense the outline into a one- or two-page checklist of issues and rules for each topic.
4. The last week: full timed papers, the cards you keep missing, and sleep.

Using AI in law study, carefully

AI can save a law student hours, and it can also invent the law. In 2023, in Mata v. Avianca, a US federal court sanctioned lawyers who had filed a brief citing court decisions that ChatGPT had made up. General chatbots also answer from everyone's law at once: another country's rule, an old version of a statute, a different court's test.

• Use AI on your own course materials, not on its general knowledge.
• Never learn a rule or case you can't trace to your syllabus, a statute or a judgment.
• Use it to quiz you and to generate practice facts, and check its answers against your outline.

That's how FlashCardz works: it writes cards only from the files you upload, quotes the line each card comes from, checks the card against that line, and opens your page in one tap. See flashcards for law school and how to study with AI.
