What changes between INAC editions
This unit's content is stable across the Q2022 syllabus period (live since September 2022, no replacement announced), so older Q2022 editions remain substantively valid - publishers reprint each academic year with a new ISBN but near-identical content. One of the best-value used buys in professional study. Note: the Q2022 Level 4 diploma is being replaced from September 2026 (last Q2022 assessments July 2028), so check which syllabus you're enrolled on before buying.
Always double-check the edition against your exam sitting before buying. When in doubt, AAT's official syllabus documents are free and definitive.
