How to structure a top-band Economics essay – Edexcel A

Economics A Level By William 24 August 2026

The place that the Economics A Level occupies between the STEM subjects and the humanities makes it uniquely awkward when it comes to writing the 25-mark essay questions. One thing I often notice from students who potentially do not achieve that A* grade is that this makes them neglect it from their technique revision, focusing on the more simply structured data response questions, and leaving their Section C questions to lose marks by being far too formulaic.

As Section C of Papers 1 and 2, along with being featured in Paper 3 twice, the question style is too big to neglect – it makes up 25% of your grade on its own.

The most common mishaps

Across the range of 25-mark responses I have read – many of which were from friends and tutees that are more accustomed to STEM backgrounds, and many from solely humanities backgrounds too – there are two main ways that this question is approached. Both are wrong. This is the reason many students find themselves stuck at 19-21 out of 25, despite having the potential to reach full marks.

The essay question, through its split between 'KAA' (Knowledge, Application, Analysis) marks, and evaluation marks, rewards a balance of specificity and quality analytical writing that students often find difficult to strike. Understanding this makes the question so, so much easier. But many focus on either one or the other, rather than both.

More to Life Than Chains

The mistake I see most prevalently – and this is partly aided by social media's many economics tutors that will convince you that there is nothing else important in the world – is a focus on chains that leaves students too preoccupied to truly unpack their writing. In the A Level Economics world (something which is far too big for what it should be) 'chains', which are analytical chains of reasoning that are useful for describing how economic changes have a knock-on effect, are spoken about like currency.

Whilst it is undoubtedly important to have your chains down to a fine art in order to access the top grades, this focus on it often leads students to become too focused on having super tight chains, even in their evaluation paragraphs which should spend more time unpacking the 'why'.

Evaluation is not just swapping sides

Especially in evaluation paragraphs, I see a lot of students echo what they write in their KAA, chain-focused paragraphs, simply swapping to the other side of the argument. For example, should the question be something like 'Evaluate the factors affecting the international competitiveness of a country/countries of your choice' (2026 Paper 2 Q7), students often write their KAA paragraphs on factors that would have a positive effect, and then their evaluations on factors that would either stop this positive effect, or would have a negative effect.

This approach is far too simplistic to access the top band for evaluation. Although correct in their sentiment, this entirely prevents their evaluation from being developed enough to meet the requirements set out in the mark scheme. Evaluation paragraphs require stronger analytical writing, rather than just presenting arguments as to other conditions that may influence the impact of the condition.

Instead, students should look to their strength in chain-building, and work on unpacking these chains, focusing on areas that are less likely or much more dependent on things such as behaviour, time, or elasticity, applying it to the context of the country or extract that the question requests and keeping it focused. Evaluation paragraphs should be focused, relevant, and deeply analytical.

The Theory of Everything

Conversely, on the KAA paragraphs, students often juggle too many potential economic factors, rather than focusing on just one or two to build long chains with. Although chains can often be explained in a single sentence, or four or five steps with arrows between them, one should not be fooled into thinking this alone will access full marks. Chains should be gently and carefully unpacked, clearly signposted, and consistently thorough, leading directly from one impact to another.

These requirements cause a conundrum for students that takes them one of two ways. The first, a continuation of the trend of 'formulaic' writing unpacked in the earlier paragraphs, often leads students to overthink and get lost within their analysis. Indeed, students often see their paper after describing one or two chains briefly, and think: "There's no way this can get me the marks I need; I have to write more." This is what I like to call The Theory of Everything. I'd be lying if I said I hadn't fallen into this trap in my early days of Economics, too.

You don't need to write about every avenue

Claiming more victims each cohort, the belief that you need to cover every possible economic factor, and open every possible door at every point, results in losing yourself in the maze to an unfortunate truth: the difference between what your textbook tells you and what an examiner wants is irreconcilable with the reality that there are an infinite number of possibilities.

I remember coming out of my exams and watching my classmates stress because they compared answers and realised they both wrote about different things. Both would forget that their answers could both be deserving of high marks, despite focusing on different factors.

It is this simple: you do not need to write about every avenue that could be affected. You only have 30-40 minutes for the question.

To those who are reading this and thinking, 'that's me... I do that', I propose the following fix: next time you finish your KAA paragraph, see your two short chains that result in four lines of work and correctly identify that there is more to do, try and flesh out your chains rather than including thirty more possibilities. Deepen your analysis. Make sure you've gathered your application marks. Even draw another diagram. These are all infinitely more effective ways to gather marks than falling victim to The Theory of Everything.

It isn't a humanities essay

That brings me to the second way in which the chain-led economic analysis causes an issue to students. This one is much more prevalent in my fellow humanities-brained students – that the essay that the question is described as is actually an essay. The 25-mark questions are not an essay in the same way Politics 30-mark questions, History 20-mark questions, or RS 40-mark questions are.

As such, there is no benefit to being unnecessarily floaty and flamboyant with your language, nor is there value in jumping around and over-analysing minute concepts. Your analysis, although deep, must be succinct, valuable, and entirely focused on addressing the concept that the question juggles with. Incredibly directly.

The Heist Method and the Importance of Diagrams

Yes, I know it may sound incredibly hypocritical, me saying both 'analyse deeply' and 'keep it brief' at the same time. But what many fail to realise is good analysis is not how much you write. Instead, good analysis is akin to pulling off a good heist. You move quickly, get in and get out, whilst making sure to get what you came for. Analysis is the same. Be brief, but in a way that still allows you to get to the point without dancing around.

This is where your diagrams come in most handy – and it is probably why teachers don't shut up about them – they allow you to apply this analysis directly to a model and show the effects. You don't need to spend sentences describing parameters or why the two lines are in the shape they are.

Examiners know the models, and as long as you can understand them and apply them relevantly to the context of your question, your diagrams are worth their weight in gold every single time. In fact, they are likely the best way to address any of the symptoms mentioned above that you identify in your writing.
