How to study law at university: a practical guide

By oosync editorial team · Updated 2026-10-14 · 6 min read

Law is one of the most reading-heavy subjects at university, and one of the most misunderstood. Many first-year students assume success is about memorising cases. In reality, law exams reward something different: the ability to identify legal issues, state the relevant rule accurately and apply it to a set of facts or an argument.

This guide covers what law assessments usually look like, how to handle cases, statutes and readings, the techniques that suit the subject, and a routine for term and exam season. It applies broadly to undergraduate law degrees in Ireland, the UK and elsewhere, but always check your own module handbooks for specifics.

What law assessments usually look like

Most law modules use some combination of the following:

• Problem questions. A scenario with facts, and an instruction such as "Advise Sarah." You identify the legal issues, explain the law and apply it to the facts.
• Essay questions. Often a statement or quotation followed by "Discuss" or "Critically evaluate." You build an argument using cases, statute and academic commentary.
• Coursework essays. Longer, researched pieces with full referencing, often using a citation style such as OSCOLA.
• Moots and presentations. Oral argument on a point of law.
• Seen or open-book exams in some modules, where you have access to materials but less time to rely on them than you think.

Problem questions and essays need different skills. Problem questions reward accurate, structured application. Essays reward argument and critical engagement with the law. Your revision should practise both.

What to do with lecture slides and readings

Lecture slides

Law slides often list cases and headings with very little explanation. Use them as a map of the topic: the legal rules covered, the order they build in and which cases the lecturer considers central. After each lecture, rebuild the slides into notes in your own words, organised around legal rules rather than around cases.

Textbooks

Your core textbook explains the law and how cases fit together. Read the relevant chapter before or after each lecture using an active method: preview the headings, read a section, recall the main points, then check. It is often the most efficient way into a topic.

Cases

You do not need to read every case in full. A sensible approach:

1. Read the textbook or casebook account first.
2. For leading cases, read the key passages of the judgment, especially the reasoning on the point you are studying.
3. Brief each important case on one card: facts (briefly), issue, decision, reasoning and principle.

Keep case notes short. What matters is the principle the case stands for and how the court reasoned, not every detail of the facts.

Statutes

Read the actual sections, not just summaries. Pay attention to definitions and to the exact wording, because problem questions often turn on a single word or condition. Note which cases interpret each provision.

Techniques that suit law

1. Organise around rules, not cases

Build each topic as a structure of legal rules, with cases attached as authority. For negligence, for example, the structure might be duty of care, breach, causation, remoteness and defences, with leading cases under each element. Drawing this as a flowchart (a form of dual coding) gives you a ready-made plan for problem questions.

2. Practise problem questions regularly

Practice testing is one of the most effective study techniques there is, and for law that means answering problem questions. Do one a week during term, not only in exam season. Use a structure such as IRAC:

• Issue: what legal question arises from these facts?
• Rule: what is the law, with authority?
• Application: how does the rule apply to these specific facts? Consider both sides.
• Conclusion: what is the likely outcome?

Most marks are in the application. Practise it most.

3. Case and principle flashcards

Flashcards suit the building blocks of law: what each leading case decided, the elements of an offence, the test for a legal concept and key statutory provisions. Keep each card to one point:

Q: What test did the court set out in [leading case] for [legal issue]? A: The test, in one or two lines, with the key words.

Review them with spaced repetition throughout the term, rather than learning cases in the final week.

4. Essay plans from memory

For essay topics, take a past question and write a plan in 15 minutes without notes: your argument, the main points, and the cases and commentary for each. Then check it against your notes. This combines retrieval with practice at the structure you will need.

5. Mix topics in practice

Real problem questions often raise issues from several topics at once. Once you have covered a few topics, mix practice questions across them so you practise spotting which issues arise. This kind of interleaving is harder but closer to the exam.

A weekly routine during term

Tutorials and seminars are where you test your understanding against others. Prepare properly, attempt every question, and pay attention to how your tutor reasons through problems.

Exam-season plan

Four weeks out: audit every topic on each module. For each, try writing a one-page outline of the rules and leading cases from memory. Rate topics as secure, shaky or weak, and gather past papers.

Three weeks out: fix weak topics, finalise topic structures and keep up flashcard reviews. Start doing problem questions from past papers untimed.

Two weeks out: do timed problem questions and essay plans daily, mixing topics. Mark them against the marking criteria and keep an error log of what you missed.

Final week: sit full timed papers. Review your error log and your topic structures. Keep reviews light in the final two days.

If your exam allows you to bring statutes or materials, practise with exactly those materials, so you know where everything is.

Common mistakes

• Case-dumping. Listing every case you know, without explaining why each one matters to the question.
• Retelling facts. Long descriptions of case facts earn few marks. The principle and its relevance are what count.
• Stating law without applying it. In problem questions, the application is where most marks are.
• Ignoring statute. In many areas, the statute is the starting point.
• One-sided answers. Good answers consider counter-arguments and alternative outcomes.
• Leaving cases to the last week. Learning hundreds of cases at once does not work. Spread it out.

Using tools sensibly

Law reading lists are long, and keeping cases, statutes and notes together helps. In oosync you can upload readings and slides into a module, annotate the PDF pages with a pen and ask questions that are answered from your own materials with citations, so you can go straight to the passage. You can also generate flashcards on cases and rules from your notes and practise with generated practice exams. Check every answer and card against the original source. In law, precision matters.

Law study checklist

1. Organise notes by legal rule, with cases as authority.
2. Brief leading cases on one card each: facts, issue, decision, principle.
3. Read the actual statutory provisions.
4. Practise a problem question or essay plan every week.
5. Use IRAC or a similar structure, and spend most effort on application.
6. Review cases and rules with spaced flashcards all term.
7. Mix topics in practice questions as exams approach.
8. Sit timed past papers in the final fortnight.
