All six areas of the 0625 syllabus - from measuring a pendulum to the Hubble constant - explained, diagrammed and self-marked. Free, no login, works on any device.
Cambridge IGCSE Physics 0625 is six subject areas, studied in this order: 1 Motion, forces and energy, 2 Thermal physics, 3 Waves, 4 Electricity and magnetism, 5 Nuclear physics and 6 Space physics. The syllabus calls them topics; every revision page on this site sits in one of them, in Cambridge's own order.
All candidates sit three papers, and which three depends on the route your school enters you for. The route also sets the highest grade you can be awarded, so it is worth knowing which one you are on before you revise.
| Route | Papers you sit | Grades open to you | What it means |
|---|---|---|---|
| Core | Papers 1, 3 and 5 or 6 | grades C to G | For candidates who have studied the Core content, or who are expected to achieve a grade D or below. Paper 1 is multiple choice on Core content only, Paper 3 is short-answer and structured questions on Core content, and the practical paper is Paper 5 or Paper 6. |
| Extended | Papers 2, 4 and 5 or 6 | grades A* to G | For candidates who have studied the Core and Supplement content, or who are expected to achieve a grade C or above. The same three papers as the Core route, examined on the Core and Supplement content together. |
Paper 1 or Paper 2 is 30% of the qualification, Paper 3 or Paper 4 is 50%, and the practical paper is 20%.
| Paper | Time | Marks | What it tests |
|---|---|---|---|
| Paper 1 - Multiple Choice (Core) | 45 min | 40 marks | 40 four-option multiple-choice questions. Core content only. AO1 and AO2. |
| Paper 2 - Multiple Choice (Extended) | 45 min | 40 marks | 40 four-option multiple-choice questions. Core and Supplement content. AO1 and AO2. |
| Paper 3 - Theory (Core) | 1 h 15 min | 80 marks | Short-answer and structured questions on the Core content. AO1 and AO2. |
| Paper 4 - Theory (Extended) | 1 h 15 min | 80 marks | Short-answer and structured questions on the Core and Supplement content. AO1 and AO2. |
| Paper 5 / 6 - Practical | 1 h 15 min | 40 marks | Practical Test or Alternative to Practical, on the experimental skills in Section 4. AO3. |
Within the written papers the split is 63% AO1 to 37% AO2; the practical paper is 100% AO3. Every mark scheme on this site tags each question AO1 or AO2, so you can see which one you are practising.
The full topic list, with every topic linked to its revision page, is on the IGCSE Physics syllabus page. Work through the areas below in order, or jump straight to what you need tonight.
Work through them in order or jump straight to what you need tonight. Each topic page teaches the content, then tests it.
Measuring quantities, describing motion, mass and weight, density, forces and momentum, energy, work and power, and pressure.
The kinetic particle model of matter, thermal expansion, specific heat capacity, melting and boiling, and the three ways heat is transferred.
Wave properties, reflection and refraction of light, thin lenses, dispersion, the electromagnetic spectrum and sound.
Magnetism, charge, current, resistance and power, circuit diagrams, series and parallel circuits, electrical safety, induction, generators, motors and transformers.
The nuclear model of the atom, nuclide notation, isotopes, fission and fusion, background radiation, alpha, beta and gamma emission, decay equations, half-life and radiation safety.
The Earth's rotation and orbit, the Moon's phases, the Solar System, elliptical orbits and gravitational fields, the life cycle of a star, light-years, redshift, the CMBR and the Hubble constant.
Knowing the content and scoring marks are two different skills. These tools train the second one.
Every command word Cambridge uses, what it actually means, and what the examiner wants to see. Includes a trainer that shows you the difference between a 1-mark and a 2-mark answer to the same question.
OpenEvery question on the site in one place. Filter by topic, command word, marks or AO1/AO2, then build a set and mark yourself against the scheme.
OpenReal student answers that score badly, the exact reason each one loses marks, and the version that scores. This is where most marks are quietly thrown away.
OpenTen random questions. Get a score, a breakdown by area, and a focused follow-up set built from whatever you were weakest on.
OpenYour Learn / Practise / Test / Mastered status for every topic, saved in this browser. Shows exactly what is left.
OpenPick the time you actually have. The plan changes to fit it.
No packs to buy, no subscription and no login. Every topic, every question and every diagram is open to any student who needs it.
