ⓘ How to read this — sources & caveats
Built from 246 real OCR / AQA / Edexcel GCSE (9–1) Maths papers (June & November 2017–2024), every question-part tagged to a topic and cross-checked against the mark scheme. Marks on multi-topic (synoptic) questions are split across their topics. Spec strands are assigned by a topic classifier. The overall Assessment Objective mix is mandated identical for every board (Ofqual: F 50/25/25 · H 40/30/30) and the estimate is calibrated to match it (verified against AQA's official AO grid). The per-topic "How it's assessed" split is calibrated from AQA's official per-question AO grid by strand & question size and applied across boards (AO follows question type) — a model, not official per-paper tags. "Longest gap since last seen" reflects past frequency, not a prediction. Trends from few sittings (n<6) are greyed as weak evidence.

Marks by spec strand
Total marks per strand across the filtered papers.
Assessment Objective mix estimated
AO1 (routine) / AO2 (reason) / AO3 (problem-solve) split by marks. The overall AO balance is mandated identical for every board (Ofqual: F 50/25/25 · H 40/30/30) and this estimate is calibrated to match it (verified against AQA's official published AO grid, which lands exactly on the mandate). For how a specific topic is assessed, see the per-topic "How it's assessed" card, which is AQA-calibrated by question type.
Hardest topics that come up a lot real data
High-frequency topics where students actually score low in real papers — the best return on teaching time. Ranked by marks-per-paper × difficulty (from Question Level Analysis: AQA + Edexcel). Click a topic to deep-dive.

Rising & falling topics
Linear trend of a topic's average marks per paper, year on year (years where the topic didn't appear count as 0) — based on past frequency, not a prediction. n = sittings behind the fit; topics with fewer than 6 sittings are not shown.

How it's assessed AQA-calibrated
AO1 (routine) / AO2 (reason) / AO3 (problem-solve) split for the selected topic, calibrated from AQA's official per-question AO grid. Where AQA has enough data for this exact topic it uses a topic-specific fingerprint (so e.g. indices reads AO1-heavy while surds reads AO2-heavy); otherwise it falls back to the topic's strand × question size. A model calibrated from the one board that publishes reliable per-question AO — not official per-paper tags.
How hard is this topic? real data
The average % of marks students actually score on this topic in real papers (Question Level Analysis: AQA both tiers + Edexcel Higher). Lower = more demanding. A descriptive past-performance figure, not a prediction.
Common mistakes examiner reports
What examiners report students get wrong on this topic, paraphrased from OCR/AQA/Edexcel examiner reports. ⭐ marks a grade discriminator (separates stronger from weaker students).
How they ask it
Specific task types for the selected topic (board & tier filtered), with the mark-scheme answer/method.
Question sizes
How many marks each question is worth, selected topic (filtered).
Pairs with…
Topics the selected topic is combined with in synoptic questions (all papers).
Where it sits in the paper
Marks by position, selected topic — early questions are usually easier, later ones harder.
Command words
What students are asked to DO across the filtered papers — solve / prove / explain… Inferred from each question's description, not the verbatim exam command, so read it as indicative; "Other" groups phrasings that didn't match a standard command word.
Top quick-win question types
The most common 1 & 2-mark question types (whole questions and sub-parts) — the quick marks. Reacts to the board filter.
Single-paper profile
Pick any paper to see its topic breakdown by marks.
Longest gap since last seen
Regular topics (in ≥5 of the filtered sittings) ranked by how long it's been since they last came up. This describes the past record — it is not a prediction that they're "due", and exam boards don't work to a rota.
Most common topic pairings
The synoptic combinations that come up most across all papers — from the ~8% of question-parts the crawl tags with two or more topics, so treat these as the strongest signals, not an exhaustive list.
