Free IGCSE chemistry notes condense bonding, the periodic table, acids and bases, rates of reaction, and organic chemistry into revisable chunks for Cambridge 0620 and Edexcel International GCSE Chemistry. Use this finder alongside our topic-wise chemistry revision guide and the main free IGCSE notes hub.

Match notes to your syllabus

Board	Code	High-weight topics in notes
Cambridge	0620	Moles, bonding, electrolysis, organic, acids/bases
Edexcel	4CH1	Check spec; organic and quantitative chemistry differ in emphasis

Chemistry notes must include balanced equations, state symbols, and mole ratio setups — summaries that skip working mislead you in 6-mark questions.

Best free sources for chemistry notes

• ZNotes Chemistry — fast recap per syllabus section.
• PMT — detailed notes and some topic questions.
• Tutopiya — Cambridge IGCSE Chemistry 0620 portal with free-tier access.
• Save My Exams alternatives — chemistry-focused comparison if you hit paywalls elsewhere.
• School practical summaries — often the best for required practicals and apparatus.

For exam technique on calculations, add mole calculations practice after reading notes.

How to revise chemistry with free notes

1. Read one syllabus subsection (e.g. electrolysis).
2. Write 5 key facts from memory — definitions, colours, products.
3. Do 3–5 past questions on that subsection only.
4. Mark with the mark scheme — note exact wording for “explain” vs “describe” (command words).

Organic chemistry benefits from mechanism-style diagrams in your own notebook even when free notes use bullet points only.

Frequently asked questions

Are free IGCSE chemistry notes accurate?

Community notes are usually good but can lag syllabus updates. Cross-check with the official syllabus and textbook.

ZNotes vs Save My Exams for chemistry?

ZNotes is fully free; Save My Exams is freemium. See the hub comparison.

How do I revise organic chemistry with free notes?

Learn functional groups and reactions from notes, then drill name reactions and products with past paper questions.

Can I use GCSE chemistry notes for IGCSE?

Not reliably — topic depth and practical emphasis differ. Stick to IGCSE-labelled resources.

Where are free notes for all IGCSE subjects?
