A-Level Physics Revision Notes
BETAFree, syllabus-aligned notes for Cambridge International AS & A Level Physics (9702) — 76 topics across AS and A2, each with worked examples and exam tips.
These revision notes work through the complete Cambridge International AS & A Level Physics (9702) syllabus, one topic at a time. They are written for students who want a clear, exam-focused summary of each part of the course — what you need to know, how it is tested, and the mistakes that cost marks. Use them alongside your textbook and past papers as you revise.
The course is split into AS Level (Units 1–11, examined in Papers 1–3) and A2 Level (Units 12–25, examined in Papers 4–5). Pick your stage below and browse by unit, or jump straight to a topic. Every note is free and needs no sign-up.
How to get the most from these notes
Read the key definitions, then close the page and write them from memory. Precise wording earns marks.
Try each exam-style question before reading the model answer, then compare your method line by line.

Frequently asked questions
Are these A-Level Physics revision notes free? ▾
Yes. All 76 topic guides are free to read in full, with no account or sign-up needed. Each one covers the key definitions, core content, worked examples, common mistakes and exam tips for that part of the Cambridge 9702 syllabus.
How is the Cambridge A-Level Physics (9702) exam structured? ▾
Cambridge assesses Physics through five papers. At AS Level, Paper 1 is multiple choice, Paper 2 is structured questions, and Paper 3 tests advanced practical skills. At A2 Level, Paper 4 is structured questions on the whole syllabus and Paper 5 tests planning, analysis and evaluation. Your AS and A2 papers together make up the full A Level.
What is the difference between AS Level and A2 Level? ▾
AS Level is the first half of the course (Papers 1–3) and can be certificated on its own. A2 Level is the second half (Papers 4–5) and builds on the AS content; together they form the full A Level. On this page the AS topics and A2 topics are listed separately so you revise the right material for your stage.
What does each revision note include? ▾
Every topic follows the same layout: an overview, key definitions in exam-precise language, the core content explained step by step, at least one worked exam-style question with a model answer, the relevant equations, a list of common mistakes to avoid, and targeted exam tips.
What is the best way to revise A-Level Physics? ▾
Active recall beats re-reading. Use a note to learn its definitions precisely, then close it and write them from memory. Work through the worked example, then attempt past-paper questions on the same topic. Watch the command words — "describe", "explain", "compare" and "calculate" each expect a different kind of answer — and check your wording against the common-mistakes list.
Do these notes follow the latest syllabus? ▾
Yes. The topics and learning objectives are aligned to the current Cambridge International AS & A Level Physics (9702) syllabus for 2025–2027. Always confirm the exact content for your exam session with your teacher or the official syllabus.
