Maths study guides

A deep-dive WJEC A2 Unit 3 Pure Mathematics B guide. Covers proof by contradiction, functions (modulus, composite, inverse, partial fractions), arithmetic and geometric series and the binomial for any index, advanced trigonometry, parametric equations, the chain, product, quotient and implicit rules, integration techniques, and numerical methods, in this 120-mark A2 paper.

A deep-dive WJEC A2 Unit 4 Applied Mathematics B guide. Covers the Statistics section (conditional probability, the Normal distribution, hypothesis testing for correlation and the Normal mean) and the Differential Equations and Mechanics section (separable differential equations, calculus kinematics, projectiles, inclines, friction and moments), in this 80-mark A2 paper.

A deep-dive WJEC AS Unit 1 Pure Mathematics A guide. Covers proof, algebra and functions, coordinate geometry, sequences and series, trigonometry, exponentials and logarithms, differentiation, integration and vectors, with the exam structure and the methods WJEC repeats in this 2 hour 30 minute, 120-mark AS paper.

A deep-dive WJEC AS Unit 2 Applied Mathematics A guide. Covers the Statistics section (sampling and data, probability, the binomial distribution, hypothesis testing) and the Mechanics section (kinematics and the suvat equations, forces and Newton's laws), with the structure of this 1 hour 45 minute, 75-mark AS paper split into Section A and Section B.
