OCR A Level Mathematics A Paper 1 2025 Mark Scheme

Download the official OCR A Level Mathematics A H240/01 Pure Mathematics June 2025 mark scheme PDF — the examiner-approved document used for awarding marks in the OCR A Level Mathematics examination series. This official mark scheme contains fully worked Pure Mathematics solutions, examiner annotations, method marks, accuracy marks, follow-through guidance, alternative methods, and detailed marking principles used by OCR examiners in 2025.

The OCR H240/01 June 2025 mark scheme covers a wide range of advanced A Level Mathematics topics including algebraic manipulation, binomial expansion, partial fractions, logarithms, trigonometric equations, parametric equations, coordinate geometry, differentiation, integration, proof by contradiction, irrationality proofs, sequences and series, vectors, transformations, calculus modelling, harmonic form, and advanced problem-solving techniques. It also explains OCR’s official marking framework, including method marks (M), accuracy marks (A), independent marks (B), follow-through (FT), special cases (SC), and examiner judgement guidance.

Students and teachers can use this PDF to understand exactly how OCR examiners reward mathematical reasoning, algebraic structure, calculus methods, proof-writing, trigonometric modelling, and clear working in A Level Mathematics examinations. Ideal for self-marking, revision practice, mock examination review, classroom moderation, and improving exam technique for the 2025/2026 OCR Mathematics A specification. Fully optimised for desktop and mobile viewing with instant PDF download access from markscheme.net.

This document is designed for OCR A Level Mathematics A students preparing for the 2026 examination series, including Year 13 students, resit candidates, independent learners, private candidates, and home-schooled students studying Pure Mathematics (H240/01).

It is especially useful for students revising calculus, algebra, trigonometry, proof, logarithms, differentiation, integration, parametric equations, coordinate geometry, sequences and series, vectors, transformations, and advanced Pure Mathematics problem-solving techniques.

The mark scheme is also highly valuable for Mathematics teachers, tutors, sixth-form departments, revision-course providers, and parents supporting A Level Mathematics revision. It can be used for examiner-standard self-assessment, worked-solution analysis, classroom moderation, AO-focused revision, and identifying common mistakes before OCR examinations.
