We classified every mark in the published Edexcel Core Pure 1 papers from 2019 to 2025 — 533 marks across 162 questions, seven series. Core Pure 1 and Core Pure 2 are compulsory for every Edexcel Further Maths candidate.
Further Maths tutoringThe headline: First-order differential equations are 13.5% of Core Pure 1. Across the published papers from 2019 to 2025, no other subtopic comes close. The top three subtopics — first-order differential equations, second-order differential equations, and 3D vector geometry — together account for 33.0% of the marks in the whole paper.
This is an aggregate classification of every mark in the published Edexcel Core Pure 1 papers that have already been sat, not a prediction of any future paper. Every question was assigned to one topic and one subtopic from the official Edexcel Further Maths specification, and its full mark value attributed to that subtopic. Historical mark share is one of the more reliable signals available for deciding what to work on first.
| Topic / subtopic | Marks | Share |
|---|---|---|
| Differential Equations | 156 | 29.3% |
| First Order | 72 | 13.5% |
| Second Order | 58 | 10.9% |
| Applications & SHM | 26 | 4.9% |
| Further Calculus | 77 | 14.5% |
| Advanced Applications | 44 | 8.3% |
| Integration Techniques | 33 | 6.2% |
| Complex Numbers | 66 | 12.4% |
| Complex Numbers Applications | 30 | 5.6% |
| Argand Diagrams | 14 | 2.6% |
| Foundations & Operations | 12 | 2.2% |
| Exponential Form & De Moivre | 10 | 1.9% |
| Further Algebra & Functions | 64 | 12.0% |
| Series | 36 | 6.8% |
| Roots of Polynomials | 28 | 5.2% |
| Further Vectors | 46 | 8.6% |
| Matrices | 44 | 8.3% |
| Determinants & Inverses | 21 | 3.9% |
| Matrix Algebra | 13 | 2.4% |
| Transformations | 10 | 1.9% |
| Proof | 29 | 5.4% |
| Polar Coordinates | 27 | 5.1% |
| Hyperbolic Functions | 24 | 4.5% |
| Definitions & Identities | 18 | 3.4% |
| Inverse Hyperbolic Functions | 6 | 1.1% |
Weight your revision toward first-order differential equations. At 13.5% of the marks, it is the single highest-leverage subtopic in this paper — more time here moves your expected mark more than the same time spent anywhere else in Core Pure 1.
The thin tail is a genuine saving. Argand Diagrams, Matrix Algebra, Foundations & Operations, Exponential Form & De Moivre, Transformations, Inverse Hyperbolic Functions have carried 12.2% of the marks between them across the seven published series. That is a real permission to deprioritise once the larger subtopics above are secure.
Choosing your Further Maths options? The exam analysis hub compares all ten option papers side by side, including Core Pure 2 — the other half of this pair.
Across the published papers from 2019 to 2025, first-order differential equations alone account for 13.5% of the marks in Core Pure 1. The top three subtopics together — first-order differential equations, second-order differential equations, and 3D vector geometry — make up 33.0% of the paper.
533 marks across 162 questions, from every published Edexcel Core Pure 1 paper across the 2019 to 2025 series — 7 papers in total.
Yes — the thinnest subtopics (Argand Diagrams, Matrix Algebra, Foundations & Operations, Exponential Form & De Moivre, Transformations, Inverse Hyperbolic Functions) have carried 12.2% of the marks between them across the published papers, which is a real basis for spending less time there once the bigger subtopics are secure.
The harder half is knowing where you stand against it — and having someone turn that into a plan with an order and a deadline.
