OCR A Level Mathematics B Mei Paper 1 2025 Mark Scheme

Download the official OCR A Level Mathematics B MEI H640/01 Pure Mathematics and Mechanics June 2025 mark scheme PDF — the examiner-approved document used to award marks in the 2025 OCR A Level Mathematics examination. This mark scheme contains full worked solutions, examiner annotations, method-mark allocation, alternative accepted approaches, assessment-objective breakdowns, and detailed mathematical reasoning guidance for every question in the paper.
The OCR H640/01 June 2025 mark scheme covers advanced A Level Mathematics topics including calculus, differentiation, integration, logarithms, partial fractions, parametric equations, kinematics, vectors, forces and friction, projectiles, moments, implicit differentiation, numerical methods, trapezium rule approximation, mechanics modelling, coordinate geometry, and proof-based algebraic problem solving. It also includes official OCR guidance on method marks (M), accuracy marks (A), independent marks (B), follow-through marking, and handling of alternative valid mathematical methods during examiner assessment.

Students and teachers can use this PDF to understand exactly how OCR examiners reward mathematical reasoning, mechanics modelling, structured algebraic working, graph analysis, calculus methods, and extended problem-solving techniques. Ideal for self-marking, revision, classroom moderation, mock exam preparation, and improving exam technique for the 2025/2026 OCR A Level Mathematics B MEI 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 B MEI students preparing for the 2026 examination series, including Year 13 students, retake candidates, independent learners, and home-schooled students studying Pure Mathematics and Mechanics (H640/01). It is especially useful for students revising calculus, logarithms, partial fractions, vectors, mechanics, projectiles, differentiation, integration, friction, moments, numerical methods, and mathematical modelling.

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