All 11 syllabus topics — free to read. Each page has clear definitions, key formulae with worked examples, diagrams explained in words, and the exact exam traps students lose marks on.
Start: Measurement → Revision PackEach topic now has tap-to-reveal flashcards for key equations and definitions - test yourself before diving into notes.
Work through each section in order. Don't skip the "common mistakes" box — those are real marks lost.
After reading each section, close the page and write the key points from memory. Check back only after you've tried.
Once you can answer questions on the topic without notes, tick it off in the revision checklist.
After finishing a topic, attempt the Physics questions in the mini paper and mark your answers.

GCE O-Level Physics is assessed by the Singapore Examinations and Assessment Board (SEAB) under syllabus code 6091. The examination consists of Paper 1 (multiple choice questions) and Paper 2 (structured questions and free-response answers). Together, the papers assess conceptual understanding, application to unfamiliar contexts, data analysis skills, and the ability to explain scientific phenomena using precise language.
All 11 topics on this page are covered in full — each with clear explanations, worked examples, Must-Know exam points, tap-to-flip flashcards, and 8 O-Level–style quiz questions. The notes are aligned to the SEAB 2026 syllabus.
Beyond the topic notes and flashcards, ScienceStar now has a complete O-Level Physics exam preparation suite covering Paper 1 MCQ, Paper 2 structured questions, graph skills, data-based unfamiliar context questions, and more.
44 O-Level Physics Paper 2–style questions across all 11 topics — kinematics, forces, energy, thermal physics, waves, electricity, magnetism, pressure, radioactivity and more. Every question has a full mark scheme showing exactly what examiners credit. Includes cross-topic challenge questions typical of Section C.
