The guide
How to write a strong academic essay
An essay is marked on your argument: a clear position, evidence for it and an honest look at the other side. The blank page is the first problem, and finding sources that back up your points is the second.
Tools that write the whole essay for you leave you with something you cannot defend in a seminar, and often with sources that do not exist. More and more universities ask you to say how you used AI.
What markers look for
An academic essay is marked on its argument: a clear position, good evidence for it, and an honest look at the strongest objection. Style matters, but a well-written essay with no argument still scores poorly.
That means the work starts before the writing. Decide what you think about the question and why, then build the essay so every paragraph moves that argument forward.
Three common essay types
The question usually tells you which one is expected.
- ArgumentativeTakes a position and defends it against objections.
- ExpositoryExplains a topic clearly, with evidence, without arguing a side.
- Compare and contrastWeighs two ideas, texts or cases against each other.
Step by step
- Question
- Position
- Evidence
- Draft
- Revise
Read the question carefully and underline what it asks you to do. Decide your position in one sentence: that is your thesis. Gather the evidence that supports it, and the best evidence against it.
Draft with one point per paragraph: make the point, give the evidence, explain how it supports your thesis and link to the next paragraph. Revise for argument first and for wording last.
Common mistakes
Avoid: Summarising instead of arguing
Do: Every paragraph should move your thesis forward
Avoid: Ignoring the other side
Do: Answer the strongest counterargument
Avoid: New points in the conclusion
Do: Pull the argument together and stop
A worked example
Point: sleep loss harms learning more than students expect. Evidence: in one study, students who slept less scored lower in their exams (Okafor & Lindqvist, 2022). Explanation: memories are strengthened during sleep, so cutting it short undoes study time. Link: this matters most in exam weeks, when sleep is shortest.
