OCR and Edexcel both offer A-level Mathematics and must cover the same mandatory pure and applied content set by Ofqual. The core material — calculus, algebra, trigonometry, statistics, and mechanics — is identical across all specifications. Differences lie in paper structure, the treatment of applied content, and exam question style.
What content is mandatory across all A-level Maths specifications?
Ofqual's A-level Mathematics subject content requires every specification to include:
- Pure Mathematics: algebra, functions, coordinate geometry, sequences, trigonometry, exponentials and logarithms, calculus (differentiation and integration), vectors
- Statistics: statistical sampling, data presentation, probability, statistical distributions (binomial, normal), hypothesis testing
- Mechanics: kinematics, forces and Newton's laws, moments
All boards — including OCR, Edexcel, and AQA — must assess all of these. The content cannot be omitted or substituted. Grade boundaries are set separately per board but calibrated to the same standard.
How do the assessment structures compare?
OCR offers two A-level Mathematics specifications: OCR Mathematics A (H240) and OCR Mathematics B MEI (H640). Edexcel offers one: specification 9MA0.
| Feature | OCR Mathematics A (H240) | OCR Mathematics B MEI (H640) | Edexcel (9MA0) |
|---|---|---|---|
| Paper 1 | Pure and Statistics (2h) | Pure and Mechanics (2h 40m) | Pure Mathematics 1 (2h) |
| Paper 2 | Pure and Mechanics (2h) | Pure and Statistics (2h 40m) | Pure Mathematics 2 (2h) |
| Paper 3 | Pure and Statistics (2h) | Pure and Statistics (2h 40m) | Statistics and Mechanics (2h) |
| Linear | Yes | Yes | Yes |
| Large data set | Yes | Yes | Yes |
OCR A has three papers of equal length; OCR MEI has two longer papers and a third; Edexcel has three papers, the first two being pure-only.
What is OCR MEI, and is it different from OCR Mathematics A?
OCR MEI (Mathematics in Education and Industry, specification H640) is a distinct A-level Maths specification co-developed with the MEI curriculum body. It is known for a more conceptual, problem-solving approach and includes more proof-based and modelling questions than many other specifications. MEI has a strong reputation particularly among students applying for mathematics or physics at competitive universities.
OCR MEI requires access to the Casio fx-991 or equivalent calculator and integrates large-data-set work differently from OCR A. Schools that enter students for OCR MEI typically do so because their teachers have been trained in the MEI approach — it is a considered pedagogical choice, not just a different question format.
Edexcel Mathematics (9MA0) splits its pure content across two dedicated papers, which some students find allows for more focused revision. The Statistics and Mechanics paper combines both applied strands. Edexcel is the most widely used A-level Maths specification in England as of 2026.
How do the exam questions differ?
OCR A questions tend to be cleanly structured, with a mix of shorter procedural questions and longer reasoning problems. OCR A has a reputation for well-paced papers that are neither excessively tricky nor perfunctory.
OCR MEI questions are deliberately designed to reward mathematical thinking and structured proof. Students who enjoy conceptual mathematics — deriving results rather than applying algorithms — often find MEI questions more interesting. Students who prefer procedural approaches sometimes find MEI papers more demanding.
Edexcel questions are often contextualised in real-world applications — population models, financial calculations, engineering scenarios. The large data set (a pre-released sample of real data, as of 2026 typically a weather dataset) features in both statistics and data-handling questions. Edexcel questions are generally well-structured and predictable in format, which can be advantageous for exam-technique-focused preparation.
Does the board matter for university applications?
No. Both OCR and Edexcel A-level Mathematics are equally recognised by universities. For Mathematics, Physics, Engineering and Economics degrees, the grade is what matters. OCR MEI has a strong reputation among mathematics departments at research universities, but no university specifies a preferred board.
Frequently asked questions
Is Edexcel Maths harder than OCR?
Neither OCR A nor Edexcel is reliably harder. OCR MEI can feel more challenging for students who prefer procedural calculation, because of its proof and conceptual emphasis. Edexcel's well-known format and large past-paper archive can make preparation feel more structured. Both are calibrated to the same national standard under Ofqual.
What is the large data set, and do I need to know it?
Yes. All A-level Maths specifications require students to work with a large data set during the course. The specific dataset varies by board and cohort year — Edexcel has historically used a weather dataset; OCR uses different data. Students should know the data set well enough to interpret it, identify anomalies, and carry out calculations using it. Questions about the large data set appear in the statistics component.
Does OCR MEI require different revision materials?
Yes. MEI is a sufficiently distinct specification that you should use MEI-specific resources: the MEI textbooks (published by Hodder), MEI-endorsed revision materials, and MEI past papers. Using Edexcel or AQA past papers is useful for building procedural fluency, but MEI past papers are essential for understanding the style of proof and reasoning questions you will encounter.
Can I use a graphical calculator in OCR or Edexcel A-level Maths?
Both boards allow graphical calculators. Neither requires a specific model, but both specify that calculators must not have symbolic algebra capabilities (CAS). The Casio fx-991EX Classwiz or Casio fx-CG50 are common choices. OCR MEI specifically integrates large data set work in a way that benefits from a calculator with statistical capabilities.
