We classified every mark in the published Edexcel Further Statistics 1 papers from 2019 to 2025 — 525 marks across 174 questions, seven series. Further Statistics 1 is one half of an option pair (with Further Statistics 2) — candidates take Core Pure 1 & 2 plus two of the four option pairs.
Further Maths tutoringThe headline: Discrete distributions are 30.5% of Further Statistics 1. Across the published papers from 2019 to 2025, no other subtopic comes close. The top three subtopics — discrete distributions, PGF Methods, and Type I & Type II Errors — together account for 63.8% of the marks in the whole paper.
This is an aggregate classification of every mark in the published Edexcel Further Statistics 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 |
|---|---|---|
| Discrete Probability Distributions | 211 | 40.2% |
| Distributions | 160 | 30.5% |
| Expected Value & Variance | 51 | 9.7% |
| Hypothesis Testing | 93 | 17.7% |
| Chi-Squared Tests | 81 | 15.4% |
| Testing a Poisson or Geometric Parameter | 12 | 2.3% |
| Probability Generating Functions | 92 | 17.5% |
| Quality of Tests | 83 | 15.8% |
| Central Limit Theorem | 46 | 8.8% |
Weight your revision toward discrete distributions. At 30.5% 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 Further Statistics 1.
The thin tail is a genuine saving. Testing a Poisson or Geometric Parameter has carried 2.3% of the marks between it 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 Further Statistics 2 — the other half of this pair.
Across the published papers from 2019 to 2025, discrete distributions alone account for 30.5% of the marks in Further Statistics 1. The top three subtopics together — discrete distributions, PGF Methods, and Type I & Type II Errors — make up 63.8% of the paper.
525 marks across 174 questions, from every published Edexcel Further Statistics 1 paper across the 2019 to 2025 series — 7 papers in total.
Yes — the thinnest subtopics (Testing a Poisson or Geometric Parameter) have carried 2.3% 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.
