Cambridge IGCSE Physics

Free revision notes for 0625 — all six topics, Core and Extended, plus the Practical Test and the Alternative to Practical, with diagrams, worked examples and exam-style questions.

Hi IGCSE Physics students

Complete revision notes for Cambridge IGCSE Physics 0625, free and open to anyone. One set of pages covers both tiers: anything only Extended candidates need (the syllabus’s Supplement) is marked EXTENDED. Every page has objectives, explanations, diagrams, a worked example and practice questions with answers. The questions are my own; several are modelled on the style of the June 2026 papers, with new numbers and contexts. — Mr. Suta

📜A note on past papers

No question here is copied from a Cambridge paper: the ones marked “modelled on” follow the skill and style of a June 2026 question with new numbers and contexts. Work through real past papers from your school as well; the subject content is the same in the 2026–2028 and 2029 syllabuses, so recent papers all test what these notes cover.
