Preparing for this qualification · ⁨Preparación para esta cualificación⁩

Core grades 1–5 and Extension grades 4–9 are separate entries.
Scientific calculators are allowed on all papers. Graphical calculators and symbolic algebra/calculus calculators are prohibited.
Use the official appendix to distinguish formulae to recall from supplied formulae.

Teaching coverage still needed · ⁨Cobertura docente aún necesaria⁩

Official question-bank boundaries, scheme alignment and all objective-level teaching coverage require the recorded review; no practice registry promotion.
