OCR As Physics A Paper 2 2025 Mark Scheme

Download the official OCR AS Level Physics A H156/02 Depth 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 2, including worked calculations, graph-analysis methods, uncertainty evaluation, experimental-design guidance, and official OCR examiner instructions used during live marking.

The OCR H156/02 June 2025 mark scheme covers major AS Physics A topics including deceleration graphs, distance-time analysis, density and uncertainty calculations, buoyancy and Archimedes’ principle, charge-carrier motion in electric fields, potential dividers, thermistors, e.m.f. and potential difference, potentiometers, free-body diagrams, power and work calculations, momentum conservation, inelastic collisions, diffraction, interference, refractive index, photon energy, and Planck’s constant investigations.

The mark scheme provides detailed examiner guidance for graph-based calculations involving acceleration gradients, areas under velocity-time graphs, uncertainty propagation in density measurements, and analysis of floating-body displacement in fluids. Students can see exactly how OCR awards compensatory method marks, accuracy marks, and practical-evaluation credit for structured Physics responses.

Extensive worked solutions are included for electrical Physics questions covering potential-divider circuits, thermistor behaviour, charge-carrier motion, e.m.f. comparisons using potentiometers, and voltmeter analysis. The document also contains detailed level-of-response marking guidance for experimental-design questions involving potentiometer circuits and LED threshold-voltage investigations used to estimate Planck’s constant.

Mechanics and waves sections include official examiner solutions for free-body diagrams, work-energy calculations, power equations, conservation of momentum, collision analysis, kinetic-energy comparisons, diffraction fringe spacing, coherent wave behaviour, refractive-index calculations, and Snell’s Law applications. Students can use the mark scheme to understand how OCR assesses calculations, scientific reasoning, graphical interpretation, and practical Physics explanations.

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

This OCR AS Physics A Depth in Physics mark scheme is ideal for understanding examiner expectations, improving calculation accuracy, refining practical-investigation 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 H156/02 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 Depth in Physics exam technique, home-educated learners, and independent candidates studying OCR AS Physics A. It is especially valuable for students practising uncertainty calculations, graph interpretation, practical evaluation, circuit 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, examiner-feedback modelling, practical-skills workshops, retrieval practice, and benchmarking student responses against live June 2025 OCR assessment criteria.
