OCR As Physics B Paper 1 2025 Mark Scheme

Download the official OCR AS Level Physics B H157/01 Foundations of Physics mark scheme from the June 2025 examination series. This downloadable PDF contains the complete examiner mark scheme for OCR AS Physics B Paper 1, including multiple-choice answers, worked calculations, practical-skills guidance, data-analysis marking points, extended-response criteria, and official examiner instructions used during live OCR marking.

The OCR H157/01 June 2025 mark scheme covers major AS Physics B topics including work done, forces, moments, current and Kirchhoff’s laws, lenses and wavefronts, number density, semiconductors, photons and LEDs, Planck’s constant, sampling and digital data, refractive index experiments, graph gradients, uncertainty, precision, and accuracy. The document provides detailed examiner guidance for numerical calculations, unit handling, significant figures, practical evaluation, graph plotting, and interpretation of experimental data.

Students can use this OCR AS Physics B mark scheme to understand exactly how examiners award marks for calculations, practical methods, graph work, scientific definitions, and evaluative explanations. The mark scheme includes accepted alternative answers, error-carried-forward rules, practical-investigation guidance, and common acceptable scientific wording for high-mark responses across Sections A, B, and C.

The paper includes worked guidance for topics such as calculating horizontal force components and work done, using Kirchhoff’s first law, lens power calculations, wavefront diagrams, photon energy calculations, determining Planck’s constant experimentally, digital sampling rates, and refractive-index practical investigations involving graph gradients and evaluation of experimental accuracy.

This OCR AS Physics B Foundations of Physics mark scheme is ideal for understanding examiner expectations, improving calculation accuracy, refining practical-evaluation skills, and mastering AO1 knowledge, AO2 application, and AO3 analytical skills required for high-level Physics responses. Pair this mark scheme with the matching OCR H157/01 June 2025 question paper on markscheme.net for complete examiner-standard revision and self-assessment. Updated for the 2025/2026 academic year, fully mobile-friendly, and instantly downloadable.

This document is designed for AS Level Physics students preparing for the 2026 OCR examination series, resit candidates improving Foundations of Physics exam technique, home-educated learners, and independent candidates studying OCR AS Physics B. It is especially valuable for students practising calculations, practical investigations, graph interpretation, uncertainty analysis, and AO1/AO2/AO3 assessment techniques under official OCR marking standards.

Teachers, Physics departments, tutors, revision-course providers, intervention coordinators, and parents can use this official OCR mark scheme for mock-exam standardisation, practical-skills workshops, retrieval practice, examiner-feedback modelling, and benchmarking student responses against live June 2025 OCR assessment criteria.
