What is this glossary hub for?

It collects subject glossaries: important terms with short definitions, grouped by syllabus topic, for AQA GCSE plus Cambridge International and Pearson Edexcel IGCSE and International A Level. The focus is technical vocabulary and “define”-style accuracy—not full notes.

How is this different from Tutopiya revision checklists or formula sheets?

Revision checklists help you track topic coverage and confidence across the syllabus. Formula sheets summarise equations and quantitative relationships. These pages are only for definitions, key terms and examiner-style wording—so they do not replace checklist or formula resources.

Are these glossaries aligned to the 2026 syllabus?

Yes. Each subject page matches the board’s specification (e.g. Cambridge codes such as 0625 and 9702; Pearson Edexcel codes such as 4PH1 and WPH units). Always confirm final objectives in your official specification for your exam session.

How do I download the glossary for free?

Open your subject page, then sign up to download a UTF-8 CSV for Excel or Google Sheets, or use the print view and save as PDF. Browsing lists on the site is free.

Why practise definitions separately?

Mark schemes reward precise technical language. Drilling terms and definitions improves answers to “define”, “state”, “outline” and “explain” questions without duplicating a topic checklist.

Is this resource free?

Yes. Viewing glossaries is free. CSV download and print-optimised export use the same quick sign-up as other Tutopiya study tools.

GCSE, IGCSE & International A Level Keywords & Key Terms — Definitions Glossary (2026) | AQA, Cambridge & Edexcel

Why keyword lists matter for full marks

Mark schemes reward correct technical terms and, for “explain” questions, clear causal reasoning. Learning definitions by topic helps you answer “define”, “state” and “outline” questions quickly and gives you a checklist before exams. Pair these lists with our revision checklists and formula sheets for quantitative subjects.

Subjects covered
