OCR As Physics A Paper 1 2025 Mark Scheme

Download the official OCR AS Level Physics A H156/01 Breadth in Physics mark scheme from the June 2025 examination series. This downloadable PDF contains the complete examiner mark scheme for OCR AS Physics A Paper 1, including multiple-choice answers, worked calculations, practical-evaluation guidance, graph-analysis methods, and official OCR examiner instructions used during live marking.

The OCR H156/01 June 2025 mark scheme covers major AS Physics A topics including Newton’s laws, acceleration and motion calculations, refractive index and total internal reflection, critical-angle experiments, microwave heating and standing waves, efficiency calculations, moments and equilibrium, spring constants, elastic potential energy, polarisation, and wave behaviour. The document also includes detailed examiner guidance on uncertainty, acceptable alternative answers, practical-method evaluation, graph interpretation, and significant-figure handling.

Section A provides the official answers for all 20 multiple-choice questions, covering a broad range of AS Physics concepts including mechanics, electricity, waves, materials, and energy transfer. The mark scheme clearly identifies the correct options used during OCR examiner marking.

Section B contains fully worked examiner guidance for structured questions involving Newton’s third law, reaction forces, acceleration calculations, refractive-index uncertainty analysis, critical-angle experiments, microwave standing-wave heating patterns, moments and equilibrium, spring-extension calculations, elastic potential energy, and polarisation-wave intensity graphs. Students can use the detailed marking points to understand exactly how OCR awards method marks, accuracy marks, compensatory marks, and practical-evaluation credit.

The mark scheme also explains OCR-specific marking conventions including M marks, A marks, B marks, compensatory C marks, error-carried-forward rules, significant-figure guidance, contradiction penalties, and practical annotation standards used by examiners during the June 2025 series.

This OCR AS Physics A Breadth in 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 techniques required for high-level Physics responses. Pair this mark scheme with the matching OCR H156/01 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 Breadth in Physics exam technique, home-educated learners, and independent candidates studying OCR AS Physics A. It is especially valuable for students practising calculations, uncertainty analysis, practical evaluation, graph interpretation, 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, examiner-feedback modelling, practical-skills workshops, retrieval practice, and benchmarking student responses against live June 2025 OCR assessment criteria.
