Free IGCSE physics notes are essential for recapping definitions, formulae, and graph skills before you attempt past papers on Cambridge 0625 or Edexcel 4PH1. This page focuses on where to find reliable free summaries — not replacing our full physics syllabus hub. Start with the free IGCSE notes hub if you need multi-subject sites.

Syllabus codes to match

Board	Code	Note focus areas
Cambridge	0625	Mechanics, thermal, waves, electricity, magnetism, nuclear
Edexcel	4PH1	Similar strands; check specification numbering

Physics rewards accurate units, clear diagrams, and showing substitution in calculations — your notes should list units and typical command words per topic.

Where to find free physics notes

• ZNotes IGCSE Physics — quick topic summaries; pair with questions (ZNotes guide).
• PMT — longer science notes; verify against 0625 topic list.
• Tutopiya portal — Cambridge IGCSE Physics 0625 with topic resources and practice.
• Formula sheet — use our IGCSE physics formula sheet alongside notes; know what is given in the exam.
• Cheat sheet — exclusive physics cheat sheet for last-stage revision.

Subject-specific revision order

1. Quantities and units — foundation for every calculation question.
2. Mechanics and motion — graphs, speed, acceleration (motion guide).
3. Electricity — circuits, V=IR, power.
4. Waves and optics — definitions and ray diagrams.
5. Nuclear and space — smaller weighting but easy marks if notes are crisp.

After each topic: closed-book recall from notes, then past paper questions on that topic only.

Free vs paid physics resources

Save My Exams and similar sites offer physics notes but often limit free access. ZNotes and PMT remain the most-used truly free note libraries; Tutopiya’s free tier adds structured practice. See Save My Exams IGCSE for a honest freemium comparison.

Frequently asked questions

What are the best free IGCSE physics notes?

ZNotes and PMT are widely used; school notes and Cambridge learner guides are often more exam-accurate. Combine with 0625 past papers.

Should I memorise all physics formulae?

Many are on the equation sheet; learn when to use each and typical rearrangements. See formulae given vs memorised.

Are free notes enough for grade 9/A*?

Notes build knowledge; past papers and mark schemes build technique. High achievers do both.

Combined Science vs separate Physics?

Combined students need 0653-aligned notes, not full 0625 depth — see free combined science notes.

Where is the parent hub for all free IGCSE notes?

Free IGCSE notes 2026 hub.
