How to Write a First-Class Essay: Structure, Argument and Critical Analysis

What markers reward in the 70%+ band and how to deliver it: a focused thesis, analytical paragraphs, critical engagement with sources, and a decisive conclusion.

By Dr. Hannah Montgomery•PhD in Clinical Psychology (UCL)•May 6, 2026

Key Academic Takeaways:

  • State your argument in the introduction; do not save it for the conclusion.
  • Every paragraph should make a point, support it, and analyse it.
  • Critical writing compares, questions, and judges sources instead of summarising them.
  • Engage with counter-arguments to show depth.

What does a First-Class essay look like?

Marking criteria for the 70%+ band usually mention the same qualities: a clear and sustained argument, critical evaluation of evidence, wide reading, and precise expression. The steps below show how to build each of these into your essay.

1. Answer the question with a thesis statement

A thesis statement is a one or two sentence answer to the essay question. Place it at the end of your introduction.

Weak: "This essay will discuss the advantages and disadvantages of remote working."
Strong: "Although remote working improves individual productivity, this essay argues that it weakens collaborative innovation unless organisations redesign how teams share knowledge."

The strong version takes a position that the rest of the essay can defend.

2. Structure the introduction

  1. One or two sentences of context.
  2. The specific issue or debate the question raises.
  3. Your thesis statement.
  4. A brief outline of how the essay is organised.

3. Build analytical paragraphs

Each paragraph needs one clear point, evidence from a credible source, and your own analysis of what that evidence means for the question. If a paragraph only reports what authors said, it is descriptive. Ask "so what?" after each piece of evidence and write the answer down.

4. Move from description to critical analysis

Descriptive writingCritical writing
States what a theory saysAssesses how well the theory explains the evidence
Lists findings from studiesCompares findings and explains why they differ
Reports one author's viewWeighs competing views and takes a position
Accepts sources at face valueConsiders method, sample, context, and bias

5. Use counter-arguments

Address the strongest objection to your position and explain why your argument still holds. This demonstrates that you have considered the debate in full.

6. Write a decisive conclusion

Restate your answer to the question, summarise the reasons that support it, and note any wider implication. Do not introduce new evidence.

7. Polish before submitting

  • Check that every paragraph links back to the question.
  • Cut filler phrases and repeated points.
  • Verify every citation against the reference list.
  • Read the essay aloud to catch awkward sentences.

Frequently Asked Questions

How do I make my essay more critical?

Compare sources against each other, question their methods and assumptions, explain why findings differ, and state which position the evidence best supports. Each paragraph should end with your own analysis, not a quotation.

How many references should a 2,000-word essay have?

There is no fixed rule, but 15 to 20 good-quality sources is typical for a 2,000-word undergraduate essay. Quality and relevance matter more than the number.
