WJEC Level 2 Additional Mathematics Past Papers

WJEC Level 2 Certificate in Additional Mathematics is an enrichment qualification for high-attaining GCSE learners in Wales who wish to extend their mathematical knowledge beyond GCSE standard into areas closer to A-Level Mathematics. The qualification is positioned above GCSE Mathematics and provides a challenging additional credential that demonstrates exceptional mathematical ability at the secondary stage. The single written paper covers four areas of advanced mathematical content. Algebra and Functions extends GCSE algebra into quadratic functions and their graphs (the discriminant, completing the square, vertex form), polynomial functions, the remainder theorem and factor theorem, algebraic inequalities (solving quadratic inequalities and expressing solutions using interval notation or on a number line), and the binomial expansion of (a + b)ⁿ for positive integer n. Coordinate Geometry covers the equations of lines and circles at depth: the general equation of a circle (x – a)² + (y – b)² = r², the condition for a line to be a tangent or secant to a circle, and the use of the perpendicular from the centre to a chord. Calculus introduces differentiation and integration of polynomial functions: dy/dx = nxⁿ⁻¹ applied to find gradients, tangent and normal equations at a point, stationary points and their classification using the second derivative, and definite integration to find the area under a curve or between two curves. Trigonometry extends beyond right-angled triangles to the sine rule (a/sinA = b/sinB = c/sinC), the cosine rule (a² = b² + c² – 2bc cosA), the area formula (½ab sinC), and exact trigonometric values for 30°, 45°, and 60° in both degree and radian measure. The qualification is comparable in content to the OCR FSMQ Additional Mathematics and the AQA Level 2 Further Mathematics, providing a Welsh-specific route to similar mathematical enrichment.
