IGCSE Physics (Cambridge code 0625) is one of the most consistently demanding Cambridge subjects. The questions test understanding and application — not just recall. This guide gives you free access to all 0625 past papers and shows how AI-powered explanations help you understand the physics behind every mark scheme answer.
Quick Answer:
IGCSE Physics 0625 past papers are free at Aixampapers.com, with AI explanations for every question including Paper 6 practical questions — the most neglected paper that costs students the most marks.

IGCSE Physics Topics — Full Syllabus
General Physics
- Measurement: length, volume, time, density

Thermal Physics
- Kinetic particle theory

- Gas laws: Boyle's law, pressure-temperature relationship
Waves and Optics
- Wave properties: frequency, wavelength, speed, amplitude
- Reflection, refraction, diffraction, interference
- Sound: longitudinal waves, speed, echo
- Light: reflection, refraction, total internal reflection
- Lenses: ray diagrams, focal length, uses
- Electromagnetic spectrum
Electricity and Magnetism
- Electrostatics: charge, electric field
- Current, voltage, resistance — Ohm's law
- Series and parallel circuits
- Electrical power and energy
- Magnetism: magnetic fields, electromagnets
- Electromagnetic induction, transformers (Extended)
- Cathode rays and CRO (Extended)

Paper 6 — Why Most Students Lose Here
Paper 6 (Alternative to Practical) is 40 marks and tests skills that most students never practise separately:
- Designing experiments: identifying variables, method, measurements to take
- Drawing and interpreting graphs: plotting correctly, finding gradient, identifying anomalous results
- Evaluating results: sources of error, improvements
- Drawing conclusions from data
These skills cannot be crammed. Students who practise Paper 6 questions specifically (not just Papers 1 and 4) consistently score higher overall. The Aixampapers AI tutor can explain why a specific experimental design is correct or incorrect — something mark schemes rarely do in enough detail.
Frequently Asked Questions
Where can I download IGCSE Physics 0625 past papers for free?
Aixampapers.com provides free IGCSE Physics 0625 past papers for all years, including Papers 1, 2, 4, and 6, with marking schemes and AI step-by-step explanations for every question.
What is tested in IGCSE Physics Paper 6?
Paper 6 tests practical skills without requiring actual laboratory work: planning experiments, analysing data, drawing graphs, identifying errors, and drawing conclusions. It is 40 marks and requires separate practice from the theory papers.
Is IGCSE Physics 0625 Extended much harder than Core?
Extended (Paper 4) includes additional topics: electromagnetic induction, transformers, CRO, nuclear fission/fusion, and more complex circuit analysis. The questions are also more application-based. Extended is significantly harder but allows grades A* through E.
How do I improve my IGCSE Physics grade quickly?
The three highest-impact actions: (1) practise Paper 6 every week, (2) master velocity-time graphs and ray diagrams — they appear every year, (3) after every past paper, use the Aixampapers AI tutor to understand every question you got wrong.
