Since the 2017 reform, every A-Level Maths specification in England covers the same prescribed content: the same pure mathematics, the same statistics and the same mechanics, set by Ofqual. No board is allowed to be easier, and grade boundaries are adjusted each year so that a grade A means roughly the same standard whichever board you sit. So if your school has already chosen a board, you are not at a disadvantage — but you do need to know how your board likes to ask its questions.
This guide compares Edexcel, AQA, OCR (A) and OCR (B, also known as MEI) on the things that actually matter to a student: paper structure, question style, the large data set, formula booklets and modelling assumptions. I teach students on all four boards, and the revision advice I give genuinely differs between them.
What is identical across all four boards
Before the differences, it is worth being precise about what does not change. Every student sitting A-Level Maths in England is examined on the same core content: proof, algebra and functions, coordinate geometry, sequences and series, trigonometry, exponentials and logarithms, differentiation, integration, numerical methods, vectors, statistical sampling, data presentation, probability, statistical distributions, hypothesis testing, kinematics, forces and Newton's laws, and moments.
- The subject content is fixed nationally — a topic like integration by parts or the binomial distribution appears on every board.
- All assessment is by written examination at the end of the course; there is no coursework on any mainstream board.
- All boards allow an approved calculator in every paper.
- Grade boundaries are set each year to maintain standards between boards, so no board gives 'easier' grades.
- The total assessment time is the same: six hours of examinations.
Paper structure: how each board splits the six hours
The most visible difference between the boards is how the exams are organised. This matters practically, because it changes how you schedule past-paper practice and what a 'full paper' feels like.
| Board | Papers | Structure |
|---|---|---|
| Edexcel | 3 papers, 2 hours each | Papers 1 and 2 are pure; Paper 3 is split into a statistics section and a mechanics section. |
| AQA | 3 papers, 2 hours each | Paper 1 is pure; Paper 2 is pure and mechanics; Paper 3 is pure and statistics. |
| OCR (A) | 3 papers, 2 hours each | Papers 1 and 2 are pure; Paper 3 covers pure and both applied strands. |
| OCR (B) / MEI | 3 papers, 2 hours each | Paper 1 is pure and mechanics; Paper 2 is pure and statistics; Paper 3 is pure and comprehension. |
Two structures deserve a comment. AQA's mixing of pure with applied content on Papers 2 and 3 means a pure-maths weakness can cost you marks on every paper, not just one. MEI's third paper includes a comprehension section built around a pre-released or unseen article — a genuinely different skill from standard questions, and one that rewards practising the MEI specimen papers specifically.
Question style: the difference you actually feel
This is where the boards diverge most in students' experience, and where I see the clearest patterns when marking students' work across boards.
Edexcel: structured, predictable, technique-heavy
Edexcel questions tend to be broken into clearly labelled parts that lead you through a problem. The style rewards clean, reliable technique: if you know the methods, the scaffolding is usually there. The trade-off is that later parts can be demanding, and the applied papers assume fluency with the large data set. Students who are accurate and well-drilled tend to thrive on Edexcel.
AQA: fewer, longer questions with more interpretation
AQA papers often include longer, more open questions, sometimes with multiple approaches possible and marks awarded for interpretation and explanation in words. Multi-mark 'explain' and 'comment' prompts are common in statistics. Students who are strong technically but reluctant to write sentences can find AQA statistics papers uncomfortable until they practise that style.
OCR (A): a middle path
OCR (A) sits between the two: mostly structured questions, with a noticeable number of 'in context' prompts that test whether you understand what a result means, not just whether you can compute it. The command words are used precisely, and 'show that' questions appear frequently.
OCR (B) / MEI: modelling and comprehension
MEI leans hardest into mathematical modelling and problem-solving in context. Questions often embed the maths in a scenario and expect you to criticise or refine a model. The comprehension paper is unique among the four boards. Students who enjoy thinking about why a method works — rather than only how — often prefer MEI; students who want to be left alone to calculate often prefer Edexcel.
The large data set: only Edexcel makes it examinable in depth
Every board expects students to have experience of working with a large data set, but Edexcel is the board where the specific data set is directly examinable. Edexcel publishes its data set (weather data from locations in the UK and overseas, among others) and expects students to be familiar with it: its variables, its units, its quirks and its gaps.
Edexcel statistics questions can assume you know, for example, which location's data is likely to show sea-breeze effects, or what the units of a given variable are, without stating it. Students who revise statistics only from generic questions are routinely surprised by this. If you are on Edexcel, spend time with the actual data set — open it in a spreadsheet, plot it, summarise it — rather than only reading about it.
Formula booklets and what you must memorise
All boards provide a formula booklet in the exam, and the booklets are similar but not identical. The crucial point for revision is the same everywhere: the booklet contains less than students assume. Standard integrals and derivatives, many trigonometric identities, the equations of motion and several statistical formulae are not given, or are given in a form that still requires you to know how to use them.
Whatever your board, print your board's actual booklet early in Year 12, and revise with it on the desk. Part of your recall practice should be writing, from blank, the list of things that are not in it. Students are often shocked in their first mock by how much they expected to be given that was not.
What the differences mean for your revision
Here is the advice I give students, board by board, once the content is learned.
- Edexcel: learn the large data set properly; drill timed papers, because the structure rewards pace and accuracy.
- AQA: practise writing one- and two-sentence explanations of statistical conclusions; mark them harshly against the mark scheme's wording.
- OCR (A): work through 'show that' and context questions deliberately; check you can interpret a result, not just produce it.
- OCR (B) / MEI: do every available comprehension-section paper; practise commenting on the suitability and limitations of models.
- All boards: mark yourself against your own board's mark schemes, because the phrasing of what earns a mark differs subtly.
And one thing that does not change: mixed-topic, timed past papers are the highest-value revision activity on every board. If you are not sure where to start, start there.
