OCR As Physics B Paper 2 2025 Mark Scheme

Download the official OCR AS Level Physics B H157/02 Physics in Depth mark scheme from the June 2025 examination series. This downloadable PDF contains the complete examiner mark scheme for OCR AS Physics B Paper 2, including worked calculations, graph-analysis guidance, experimental-method answers, practical-evaluation criteria, and official OCR marking instructions used during live assessment.

The OCR H157/02 June 2025 mark scheme covers major AS Physics B topics including internal resistance, current and charge, Newton’s second law, trolley-and-runway practical investigations, Young modulus calculations, resistance and resistivity, potential dividers, LDR circuits, energy transfer in resistors, rocket propulsion, momentum, impulse, and ion-thruster comparisons. The mark scheme also includes detailed guidance on graph interpretation, uncertainty, experimental reliability, proportionality, data analysis, and extended evaluative responses.

Students can use this OCR AS Physics B mark scheme to understand exactly how OCR examiners award marks for calculations, practical investigations, graph plotting, evaluation questions, and long-form analytical responses. The document includes accepted alternative answers, error-carried-forward rules, significant-figure guidance, level-of-response criteria, and practical-science expectations used by OCR examiners during the June 2025 series.

The paper includes worked guidance for topics such as determining internal resistance from graphs, evaluating Newton’s second law experimentally, calculating Young modulus, analysing resistance uncertainty, using potential-divider equations with LDRs, interpreting sensor sensitivity, modelling rocket propulsion using momentum and impulse, and comparing ion thrusters with chemical rockets using efficiency and force calculations.

This OCR AS Physics B Physics in Depth 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 H157/02 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 Physics in Depth exam technique, home-educated learners, and independent candidates studying OCR AS Physics B. It is especially valuable for students practising graph interpretation, practical investigations, extended calculations, 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, examiner-feedback modelling, retrieval practice, and benchmarking student responses against live June 2025 OCR assessment criteria.
