Maths, topic by topic
One page per topic: the ideas on one screen, the marks the mark schemes report students losing, exam-style drills with full working, and the tools that train it. 26 of 28 live — the rest are on the way.
A-level Pure
Edexcel 9MA0 Papers 1 & 2 — the core of the qualification.
Proof
Deduction, exhaustion, counter-examples and proof by contradiction.
Algebra & functions
Polynomials, the factor theorem, composite/inverse functions and the modulus.
Coordinate geometry
Straight lines, circles, tangents and intersection conditions.
Sequences & series
Binomial expansion, arithmetic and geometric sequences, sums to infinity.
Trigonometry
Radians, sectors, identities, R cos(θ + α) and trigonometric modelling.
Exponentials & logarithms
Log laws, solving equations, e and ln, and log-linear modelling.
Differentiation
First principles, product/quotient/chain rules, tangents and rates of change.
Integration
Indices before you integrate, substitution, areas and the trapezium rule.
