Most law students who receive a 2:1 rather than a first are not short of legal knowledge. They know the cases and they understand the principles. The gap is almost always technical, namely how the essay is constructed, how arguments are developed, and how evidence is deployed.

This guide covers everything: how to read a question properly, how to plan, how to structure your introduction, body paragraphs and conclusion, and the specific techniques that separate first-class answers from good ones. It applies to undergraduate law essays, GDL and PGDL assessments, and most postgraduate law modules.

What markers are actually looking for

Before writing anything, it helps to understand what a first-class mark represents in practice.

Most law schools use marking criteria that reward three things above all else: argument, analysis, and authority.

Argument means that your essay has a clear, sustained position that it develops and defends from beginning to end. It is not a balanced summary of the law followed by a vague conclusion. It is a thesis (a claim) which your essay proves.

Analysis means that you do not simply describe the law, but you interrogate it. You explain why cases were decided as they were, what principles they establish, where they conflict with other authority, and what the implications are. Description tells the marker what the law is. Analysis tells them what it means.

Authority means that every claim you make is supported by something: either a case, a statute, or an academic argument. But authority is only valuable when it is used precisely. Citing a case is not the same as using it.

A marker reading a first-class essay should be able to follow a single coherent argument from the first sentence to the last. Every paragraph should advance that argument. Every piece of evidence should be deployed, not just mentioned.

How to read the question

The most common reason students write excellent essays that miss the question is that they did not read the question carefully enough. This sounds obvious. It is not.

Every law essay question contains a directive word that tells you exactly what intellectual task you are being asked to perform. These words have specific meanings and require different approaches.

Discuss — the broadest instruction. You are being asked to explore the topic from multiple angles, consider different perspectives, and reach a reasoned conclusion. A discussion essay that simply describes without taking a position will not achieve a first.

Critically analyse — you are expected to examine the law in depth, identify its strengths and weaknesses, evaluate competing arguments, and reach a clear conclusion. The word "critically" does not mean negatively — it means rigorously.

Evaluate — you are being asked to make a judgment about the effectiveness, fairness, or coherence of a legal rule, doctrine, or argument. Evaluation requires criteria. What standard are you measuring against?

Examine — similar to analyse, but with an emphasis on unpacking and explaining the components of a legal doctrine or argument in detail.

Consider — broadly similar to discuss, often used in problem-adjacent questions asking you to weigh up legal arguments.

To what extent — you are expected to agree partially, not entirely. These questions invite nuance. A blanket "yes" or "no" will not score highly.

Beyond the directive word, identify the precise scope of the question. What is the exact legal issue being asked about? What is excluded? What time period, jurisdiction, or area of law is in focus? Underline the operative words before you write a single sentence of your plan.

Planning before writing

The best law essays are planned for longer than most students expect. A plan is not a list of topics to cover. It is a map of an argument.

Start with your conclusion. Before you write the introduction, decide what your answer is. What is the essay arguing? If you cannot state your central claim in one sentence, you are not ready to write.

Once you have your conclusion, work backwards. What are the three or four main points that lead to that conclusion? Each of these will become a section of your essay. Each section should be a step in the argument, not a new topic.

For each section, identify the legal authority you will use and — crucially — what you will do with it. Do not plan "I will discuss the case of X." Plan "I will use X to show that Y, and then explain why this creates a tension with Z."

A strong plan for a 2,000-word essay might take 15–20 minutes. For a 3,000-word essay, allow 25–30 minutes. This time is never wasted. It prevents the most common essay failure: a piece that covers a lot of ground but argues nothing.

The introduction

A first-class introduction does four things, in roughly this order.

1. Opens with a statement of the issue, not a definition

Many students begin with a definition: "Negligence is a tort established in Donoghue v Stevenson [1932]..." This is a description, not an opening. It tells the marker nothing about your argument and signals that the essay will summarise rather than analyse.

A stronger opening engages immediately with the tension, debate, or problem at the heart of the question. This might be a short observation about a doctrinal tension, a reference to an academic debate, or a precise statement of what is contested.

Example of a weak opening: "This essay will discuss the doctrine of promissory estoppel and its role in contract law."

Example of a stronger opening: "Promissory estoppel has long occupied an uneasy position in English contract law — celebrated for its equitable foundations, yet persistently constrained by a judiciary reluctant to allow it to act as a cause of action. This tension reflects a deeper conflict between the law's commitment to consideration and its aspiration to prevent unconscionable conduct."

The second version does the same contextual work but immediately signals analytical intent and introduces the central tension the essay will explore.

2. Provides only the context the reader needs

Background should be brief. Two to three sentences that orient the reader: the relevant area of law, the core doctrine or issue, and why it matters. Avoid rehearsing the entire legal history of a topic in the introduction. Save the substance for the body.

3. States the argument clearly

This is the thesis statement. It should be explicit, specific, and confident.

Weak: "This essay will examine whether the current law on occupiers' liability is satisfactory."

Strong: "This essay argues that the Occupiers' Liability Acts of 1957 and 1984 create an internally inconsistent framework that inadequately protects lawful visitors while imposing disproportionate obligations on occupiers, and that judicial interpretation has compounded rather than resolved this tension."

The second version tells the marker exactly what the essay will argue. They can immediately assess whether the body paragraphs deliver on that promise.

4. Signposts the structure

One or two sentences outlining how the essay will proceed. This should be substantive, not mechanical.

Weak: "First, the law will be discussed. Then some cases will be examined."

Strong: "The essay first examines the doctrinal foundations of the duty of care before analysing the extent to which the Caparo test has introduced coherence or uncertainty into its application, before concluding that recent case law suggests a shift toward a more flexible, policy-driven approach."

Body paragraphs

Each body paragraph should make, develop, and evidence one point. One paragraph, one point. If you find yourself needing to introduce a new idea mid-paragraph, that idea belongs in its own paragraph.

The most reliable structure for a law essay paragraph is a variation of IRAC (Issue, Rule, Application, Conclusion) adapted for essay rather than problem question writing. In essay form, this becomes:

• Point — state the argument being made in this paragraph.

• Explanation — explain the legal principle or doctrine that underpins it.

• Authority — introduce the case, statute, or academic source that supports it.

• Analysis — explain what the authority shows, why it matters, and what its limitations are.

• Link — connect the paragraph's conclusion back to the overall argument and forward to the next paragraph.

Here is an example of a weak paragraph and a rewritten version applying this structure.

Weak paragraph (descriptive): "In Caparo Industries plc v Dickman [1990], the House of Lords established a three-stage test for duty of care. The test requires foreseeability of damage, proximity between the parties, and that it is fair, just and reasonable to impose a duty. This case is important in negligence law."

Stronger paragraph (analytical): "A central weakness of the modern duty of care framework is the indeterminacy introduced by the third limb of the Caparo test. In Caparo Industries plc v Dickman [1990] AC 605, the House of Lords held that a duty of care arises where damage is foreseeable, the parties are in a relationship of proximity, and it is fair, just and reasonable to impose a duty. While the first two criteria provide relatively concrete guidance, the third operates as an open-ended policy valve. As Lord Bridge acknowledged, the concept of what is 'fair, just and reasonable' resists precise definition, which has led to inconsistent application across the lower courts. This is particularly evident in cases involving pure economic loss, where courts have reached divergent conclusions on materially similar facts. The indeterminacy of the Caparo framework therefore creates unpredictability for claimants and defendants alike — a problem that subsequent refinements, including the incrementalism affirmed in Robinson v Chief Constable of West Yorkshire [2018], have not fully resolved."

The second version makes a clear point (indeterminacy is a weakness), explains the legal rule, uses the case analytically rather than descriptively, identifies a specific problem, introduces a counter-consideration, and links forward. That is what first-class writing looks like.

Using case law analytically

The most common technical failure in law essays is citing a case without using it. Students write: "In Donoghue v Stevenson [1932], Lord Atkin established the neighbour principle." This is description. The marker already knows what Donoghue v Stevenson decided.

Analytical use of a case means asking and answering four questions:

• What did this case decide? (one brief sentence)

• Why was it decided that way? (the reasoning)

• What does this mean for the argument being made? (the analytical payload)

• What are its limits?(the critical dimension that elevates the analysis)

You do not need to answer all four questions for every case. But you should be asking them. A case that appears in your essay and is only cited as authority for a proposition, without any engagement with the reasoning or implications, is a missed opportunity.

For GDL and PGDL students working across multiple subjects simultaneously: depth over volume. Two cases deployed analytically will always outscore five cases cited descriptively.

Using academic commentary

Academic sources serve two functions in a law essay: they can support your argument, or they can give you a position to engage with (to agree with, qualify, or push back against).

Using an academic source only to agree with it is the weaker use. It adds authority but not analytical dimension. The stronger approach is to use academic commentary as a point of engagement: you introduce the argument, explain why it is persuasive or compelling, and then either endorse it with your own analysis or identify where it falls short.

For example: "Professor Stapleton has argued that the incremental approach to duty of care produces 'invisible' distinctions that are unprincipled in effect if not in intention. This critique has force: the courts' reluctance to articulate the policy factors driving decisions in pure economic loss cases makes it impossible to predict outcomes with confidence. However, Stapleton's analysis may understate the pragmatic value of judicial restraint in a context where the consequences of an expansive duty would be commercially unworkable."

This approach (introduce, engage, qualify) is what distinguishes first-class use of secondary sources from the 2:1 version that simply quotes a scholar and moves on.

When referencing academic commentary, always use OSCOLA referencing. A guide to OSCOLA citation is available in our resources section.

Counter-argument technique

A first-class essay does not only present the strongest version of its own argument. It anticipates the best objection to that argument and addresses it.

This is called the steel-man technique. Rather than attacking a weak version of the opposing view, you present the strongest possible version of it before explaining why your position is nevertheless correct.

The structure is: acknowledge the counter-argument clearly and fairly, concede any part of it that has force, then explain why it does not undermine your overall thesis.

"It might be argued that the courts' cautious approach to pure economic loss is justified on the grounds that an expansive duty would expose defendants to liability of indeterminate scope — the concern Lord Denning identified in Spartan Steel & Alloys v Martin [1973]. This concern has genuine force: the potential for cascading liability in a complex commercial economy is not trivial. However, the breadth of the exception is disproportionate to the risk it seeks to manage. The complete exclusionary rule for pure economic loss, as applied in cases such as Cattle v Stockton Waterworks (1875), denies recovery in circumstances where the claimant's loss is entirely foreseeable and the defendant's conduct is plainly wrongful. A more calibrated approach — admitting recovery where the loss is sufficiently proximate and the defendant had specific knowledge of the claimant's reliance — would address the floodgates concern without the injustice of a categorical bar."

Addressing counter-arguments is what most students skip because it feels like undermining your own position. It does the opposite. It signals to the marker that you understand the full complexity of the issue and that your conclusion is not naive.

The conclusion

The conclusion should be the shortest substantive section of the essay. It does not introduce new material, new cases, or new arguments. It does three things:

1. Restates the central argument, not as a copy of the thesis statement, but as a summary of what the essay has demonstrated. The difference is that now you have the analysis behind you, so you can state the conclusion with greater precision.

2. Draws together the threads, showing briefly how the main points of the essay fit together to support the thesis. One or two sentences is enough.

3. Closes with a forward-looking or reflective observation. This might be a comment on the future development of the law, an unresolved tension, or a broader implication of your argument. It should flow directly from the analysis. It should not feel like a sudden expansion of scope.

What a conclusion should not do: begin with "In conclusion, this essay has shown..." as this is the weakest possible opening for a final paragraph. It signals to the marker that the conclusion will summarise rather than synthesise.

Common mistakes that drop a first to a 2:1

1. Describing rather than analysing. Telling the marker what the law is rather than what it means. Every paragraph should have a point, not just content.

2. No clear thesis. An essay that "considers" multiple views without ever taking a position. Balanced description is not analysis.

3. Burying the argument. The strongest statement of your argument appears in paragraph five rather than the introduction. Markers should know your position from the first page.

4. Over-quoting. Long block quotations from cases or academics. Quote sparingly, use a phrase, not a paragraph. Paraphrase and analyse the rest.

5. Under-citing. Making claims, especially about the state of the law or academic opinion, without authority. Every legal proposition needs a source.

6. Padding. Long introductions that take a paragraph to say what one sentence could say. Markers notice word economy. Concision signals analytical confidence.

7. Weak topic sentences. Opening a paragraph with "Another issue is..." or "Furthermore, it should be noted that..." These sentences say nothing. Your topic sentence should state the paragraph's point directly.

8. Ignoring the question in the conclusion. Conclusions that summarise the essay without actually answering the question set. Return to the exact words of the question in your conclusion.

First-class essay checklist

Before submitting, work through this:

• Does my introduction state a clear argument, not just an aim?

• Does every paragraph have one identifiable point in the topic sentence?

• Have I used each case analytically, engaging with reasoning and implications, not just as a citation?

• Have I engaged with at least one counter-argument and addressed it?

• Have I used academic commentary as something to engage with, not just cite?

• Does my conclusion synthesise rather than summarise?

• Does every paragraph advance the overall argument?

• Have I answered the exact question set?

• Is every legal proposition supported by authority?

• Is my referencing in OSCOLA format throughout?
