Words

One vocabulary space, with two ways to browse it.

Browse by topic, then narrow the current bank with search and course-level filters.

Use A–Z when you know roughly what the word is called and want a fast alphabetical lookup.

Source note: the course banks are teaching-focused selections built from the supplied Pearson Edexcel and IB subject specifications/guides. The IB AA and AI practice banks follow the five IB syllabus topics. IB banks now include an explicit prior-learning layer from the guide. SL banks contain common prior learning plus SL vocabulary; HL banks also include the guide’s HL-only prerequisites and AHL vocabulary. Definitions and examples are rewritten in controlled English for EAL accessibility. Command words, Everyday English comparisons and Compare/Watch out notes are teaching support rather than copied source glossary text. The Year 7, 8 and 9 banks remain fuller reference glossaries.

Flashcards

Say the meaning before you flip. Rate each card so weaker words return sooner.
