The current 2018–current dataset covers 2 topics, 733 topic questions and 1,760 marks. Each MCQ or structured part counts as one item, and each topic counts only the parts tagged to it, so the ranking reflects exam exposure rather than the number of question stems. Rows also carry paper count, mark total and year range for cross-unit comparison. The native table reproduces every figure in curriculum order. ## Topic question count and mark distribution Topics are on the vertical axis and sorted from highest to lowest. Only the parts whose knowledge graph matches a topic are counted for that topic, and percentages are each row's share of the tagged total in that chart. A part tagged to several topics is counted in each bar, so the bars are not a partition of the unit total. ### Questions by topic question items - [Waves and Particle Nature of Light](https://www.examsci.com/topics/edexcel-ial/physics/physics-unit-2-wph12/waves-and-particle-nature-of-light/) (22 papers) — 468 · 63.6% - [Electric Circuits](https://www.examsci.com/topics/edexcel-ial/physics/physics-unit-2-wph12/electric-circuits/) (22 papers) — 268 · 36.4% ### Marks by topic marks - [Waves and Particle Nature of Light](https://www.examsci.com/topics/edexcel-ial/physics/physics-unit-2-wph12/waves-and-particle-nature-of-light/) (22 papers) — 1,138 · 64.2% - [Electric Circuits](https://www.examsci.com/topics/edexcel-ial/physics/physics-unit-2-wph12/electric-circuits/) (22 papers) — 634 · 35.8% ## Topic comparison matrix Curriculum order is by syllabus number, then alphabetically.

Open a topic to see the question numbers, marks and the session each one comes from, then follow the link into the original paper. **How many topics are in the current WPH12 syllabus?** This page lists 2 topics tagged to the current syllabus across 22 WPH12 papers (2019–2026). Topics are ordered by syllabus number, then alphabetically. **How are question counts and marks calculated?** Each MCQ counts as one question item and each structured part counts as one item. Marks come from the official part marks. Only parts whose knowledge graph matches a topic are counted, and a part tagged to more than one topic is counted against each topic, so topic rows describe exam exposure rather than a partition of the paper. **Why is there no topic chart on the D1 index?** The D1 index intentionally stops at the paper-code level. Topic names are only shown after a code is selected, which prevents two units from claiming the same topic phrase or URL. **Which sessions are included?** All sessions tagged to the current syllabus are included, covering 2019–2026. Questions without a recognised syllabus tag are treated as current so they do not disappear from the index. --- Full page with native tables, bar charts and Practice Hub links: https://www.examsci.com/topics/edexcel-ial/physics/physics-unit-2-wph12/
