Expressions, equations, sequences, quadratics, and rearranging formulas with method marks in mind.
Algebra sits underneath a large share of GCSE Maths and shows up in both short and multi-step questions.
Paper focus: Core across every paper. Tiers: Foundation and Higher.
Separate skills into expanding, factorising, solving, and rearranging so students can see exactly what breaks down.
Start with Expanding and simplifying brackets, then use the app tools to practise, upload an answer, or ask for an explanation.
Open notes and exam questionsEach revision note is built as a short lesson with theory, worked examples, quick exercises, and exam-style questions with marking guidance.
