OCR As Mathematics A Paper 1 2025 Mark Scheme

Download the official OCR AS Mathematics A H230/01 Pure Mathematics and Statistics June 2025 mark scheme PDF — the examiner-approved document used for awarding marks in the 2025 OCR AS Level Mathematics examination. This comprehensive mark scheme contains full worked solutions, mark allocations, accepted alternative methods, examiner annotations, statistical reasoning guidance, and assessment-objective explanations for every question in the paper.

The OCR H230/01 June 2025 mark scheme covers a wide range of AS Level Mathematics topics including logarithms, algebraic manipulation, integration, differentiation, coordinate geometry, circles, trigonometric identities, binomial expansion, vectors, sequences and series, statistical correlation, interquartile range, hypothesis testing, probability distributions, and interpretation of statistical data. It also includes official OCR marking guidance on method marks (M), accuracy marks (A), independent marks (B), explanation marks (E), follow-through marking, and handling of alternative correct methods during examiner assessment.

Students and teachers can use this PDF to understand exactly how OCR examiners reward mathematical reasoning, statistical interpretation, algebraic accuracy, proof structure, and problem-solving methods. Ideal for self-marking, revision, classroom moderation, mock examination review, and improving exam technique for the 2025/2026 OCR AS Mathematics A specification. Fully optimised for desktop and mobile viewing with instant PDF download access from markscheme.net.

This document is designed for OCR AS Level Mathematics A students preparing for the 2026 examination series, including Year 12 students, resit candidates, private candidates, independent learners, and home-schooled students studying Pure Mathematics and Statistics (H230/01).

It is especially useful for students revising logarithms, algebra, integration, differentiation, trigonometric identities, vectors, circles, coordinate geometry, probability, hypothesis testing, statistics, correlation, and sequences and series.

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