A-Level Philosophy Essay Method: How to Write for 25 Marks

The first time I set a timed philosophy essay with my Year 13 group at Loreto College in Manchester, about half the class wrote what I'd call "intelligent summaries" — accurate, well-read, completely missing the point. The other half attempted to argue, but buried the argument under so much hedging that the examiner would never have found it.

Neither approach earns 25 marks. Both are fixable once you understand what the mark scheme actually rewards.

This guide walks through the A-Level philosophy essay method from question analysis to final sentence, with the exam board differences (AQA, OCR, Edexcel) where they matter. It's aimed at Year 13 students preparing for a 3-hour paper with two 25-mark essays.

What does a 25-mark philosophy essay actually require?

The short answer: A clear thesis, sustained argumentation with named philosophers, precise use of technical vocabulary, and a conclusion that takes a position. Around 800–1,000 words in exam conditions, written in roughly 40–45 minutes per essay.

The longer answer involves understanding how examiners read these papers. At AQA, OCR and Edexcel, the top band (21–25 marks) consistently rewards three things: analytical clarity, evaluative confidence, and philosophical precision. A student who hedges every claim, summarises three philosophers without committing to a view, and writes "there are arguments on both sides" will hover around 14–16. The difference between a C and an A isn't usually knowledge — it's the willingness to argue.

Hume puts it well. In the Enquiry Concerning Human Understanding, he writes that every argument should be traced back to impressions and ideas. At A-Level, your argument should be traceable too: from claim to reason to evidence to conclusion.

What you need before you start writing

Before the plan, three things.

Know your exam board's specification well enough to spot which philosophical problems are genuinely in scope. AQA Philosophy covers epistemology (perception, the nature of knowledge) and metaphysics of God (arguments for God's existence, the nature and existence of God) as two distinct units. OCR Religious Studies includes Philosophy of Religion and Ethics as separate components. Edexcel Religious Studies covers similar ground but with slightly different emphasis on the cosmological and teleological arguments. The core philosophers overlap heavily: Plato, Aristotle, Descartes, Hume, Kant, Mill.

Know two or three philosophers deeply rather than six superficially. An essay that cites Descartes on the ontological argument with genuine precision beats one that name-checks Anselm, Descartes, Plantinga, Kant and Hume in rapid succession without landing on any of them properly.

Know the difference between description and analysis. Description: "Kant argues that the ontological argument is flawed." Analysis: "Kant's claim that existence is not a predicate undermines Descartes' ontological argument by showing that adding 'exists' to a concept adds no new information — the concept of a maximally perfect being is therefore no more informative with existence included than without."

The second version earns marks. The first loses them.

Step 1: Read the question for what it's actually asking

Philosophy exam questions at A-Level tend to take three forms:

Direct assessment — "Critically assess the design argument." You are being asked to evaluate, not just present.

Quote plus assess — "'The ontological argument is unconvincing.' Discuss." You need to engage with the claim, support it, and consider objections.

Comparison — "Compare and contrast empiricist and rationalist approaches to knowledge." You need to identify the real point of disagreement, not just list views.

The most common error I see — and I've marked hundreds of these papers — is treating an "evaluate" question as a "describe" question. The question "To what extent does Hume's fork undermine rationalist epistemology?" is not asking you to explain Hume's fork. It's asking you to argue about what it undermines, and how far.

Underline the command verb. Then ask: what would a direct, committed answer to this question look like? Write that answer in one sentence before you do anything else. That sentence is your thesis.

Step 2: Build a plan in 5 minutes

A-Level philosophy essays are not long. In exam conditions you have 40–45 minutes and need to produce roughly 800–1,000 words. Planning 15 minutes of that is too long. Five minutes, maximum.

Your plan needs four things:

Your thesis (the answer you're going to argue for).

Two or three arguments in support, each attached to a philosopher or a named argument.

The strongest objection, stated fairly and precisely.

Your response to that objection — which either defeats it, qualifies it, or concedes something while defending the main claim.

That's it. Paragraph one: introduce the question and state your thesis. Paragraphs two and three: develop your main arguments. Paragraph four: the objection. Paragraph five: your response. Final paragraph: conclusion.

Students who spend 20 minutes planning often run out of time on the writing. A plan that fits on half a page of rough paper in five minutes is better.

Step 3: Write an introduction that commits

The introduction is where most marks are lost or won, and where most students go wrong in the same way: they introduce the question without taking a position.

An introduction that says "philosophers have debated the existence of God for centuries and there are many different arguments" tells the examiner nothing except that you know the debate exists. It earns nothing.

An introduction that says "I will argue that the cosmological argument fails because the concept of a necessary being is incoherent, and that Hume's objections in the Dialogues Concerning Natural Religion are decisive on this point" tells the examiner exactly where you stand. It sets up everything that follows.

You don't need more than three or four sentences: state what the question is asking, state your thesis, and briefly indicate your main line of argument. Twenty lines of scene-setting is not an introduction — it's a delay tactic.

One student I taught last year in Manchester, I'll call her Priya, was sitting the AQA paper with a predicted B. Her introductions were always three paragraphs of context. We spent two sessions cutting them to three sentences. She got an A. The content hadn't changed — the structure had.

Step 4: Develop arguments with precision

Each argument paragraph should do three things: state the argument clearly, connect it to a named philosopher or text, and explain why it matters for your thesis.

The structure I give my students: claim → reasoning → philosophical grounding → implication.

Example, for an essay arguing that empiricism offers a more convincing account of knowledge than rationalism:

Hume's fork provides a powerful framework for limiting the scope of genuine knowledge. By dividing all meaningful propositions into relations of ideas (analytic, knowable a priori) and matters of fact (synthetic, knowable only through experience), Hume showed that rationalist claims about substantive knowledge of reality through reason alone fail to meet either criterion. A claim like "God exists necessarily" is neither a tautology nor verifiable through sensory experience — it falls, in Hume's phrase, into "sophistry and illusion." This cuts the ground from under Descartes' certainty about the existence of God derived from the concept of a perfect being.

That paragraph is about 110 words. It's specific, it's argued, it connects to the thesis. It names a philosopher and a text. It earns marks.

What it doesn't do: spend three sentences summarising Hume's life or explaining what empiricism is in general terms. The examiner knows what empiricism is. Prove you can use it.

Step 5: Handle the objection properly

The evaluation section is where students most clearly differentiate themselves. A genuine engagement with the strongest objection to your view earns far more marks than a tour of every possible counterargument.

Pick the objection that most threatens your thesis. State it in its strongest form — don't give yourself an easy target. Then either show why it fails, or concede something while explaining why your main claim still holds.

On the empiricism example: the strongest objection is probably from Kant. If Hume is right, mathematical knowledge (relations of ideas) would be merely analytic and tell us nothing about reality. But Kant argues in the Critique of Pure Reason that mathematical propositions are synthetic a priori — they extend knowledge but are not grounded in experience. If Kant is right, Hume's fork is too crude to account for mathematics, and the rationalist case for a priori substantive knowledge remains open.

A good response doesn't simply dismiss this. It might concede that Kant identifies a genuine problem for empiricism, while arguing that Hume's empiricist constraints still hold for metaphysical claims (as opposed to mathematical ones), which is the domain that matters for the God debate.

That kind of move — concede the point, hold the thesis — is what separates a 21-mark essay from a 16-mark one.

Step 6: Conclude with a position

The conclusion is short. Five or six sentences. It does not summarise every philosopher you've mentioned. It answers the question.

State your thesis again, more precisely than you did in the introduction, because now you've argued for it. Acknowledge what you've had to concede. Say why your main claim survives. Then stop.

The phrase "there are arguments on both sides" should never appear in a conclusion. It's a signal to the examiner that you haven't committed to a view. At A-Level, committing to a view and defending it well is exactly what's rewarded.

The mistakes that cost grades

Summarising instead of arguing. Knowing what Descartes says is not the same as using Descartes to argue something. Every mention of a philosopher should be in service of your thesis, not just an entry in a catalogue.

Hedging every sentence. "Some philosophers think X, while others think Y, and there are valid points on both sides." This earns nothing. You're writing an essay, not chairing a panel.

Misusing technical terms. Calling the ontological argument "empirical" when you mean "experiential" tells an examiner your vocabulary is shaky. It raises doubt about everything else. Use terms precisely or not at all.

Skipping the objection. An essay that argues one side without engaging the other reads as partial. Examiners want to see that you understand the debate from both ends.

Running out of time on the conclusion. If you're writing the last essay with 8 minutes left, do not expand your argument section. Write the objection in two sentences and a proper conclusion in four. A structured answer with a real conclusion beats an unfinished one.

A note on exam board differences

For AQA Philosophy, the two units are assessed separately. Your essay on epistemology should not drift into arguments about God, and vice versa. The mark scheme rewards staying within the unit's conceptual frame.

For OCR Religious Studies (Philosophy of Religion component), you're likely to encounter questions framed around the strengths and weaknesses of arguments. The examiner isn't looking for a survey — they want you to reach a conclusion about which is stronger, and justify it.

For Edexcel Religious Studies, the extended writing questions reward drawing on the philosophical tradition and applying it to the specific formulation in the question. Don't ignore the exact wording. A question about the "classical" design argument wants engagement with Paley and Aquinas. Jumping to the fine-tuning argument without grounding it is a missed opportunity.

All three boards mark on similar criteria: knowledge and understanding, analysis and evaluation, the quality of argument. The relative weighting shifts slightly, but the method is the same.

---

The philosophy essay is a learnable skill. I've seen students come into Year 13 unable to write more than a paragraph of connected argument and leave with A grades. What changed wasn't their intelligence — it was their understanding of what the question is asking and their willingness to commit to a position.

If you want to work through practice questions with immediate feedback on structure and argument, EduBoost's A-Level tutoring walks you through past paper questions step by step. You can practise the introduction-plan-argument sequence as many times as you need.

And if you're also working on GCSE alongside A-Levels, our guide to GCSE maths revision over 12 weeks applies the same structured-practice logic to a very different subject. The underlying principle — know what the examiner rewards, practise that specifically — holds across the curriculum.
