OCR A Level Physics A Paper 2 2025 Mark Scheme

Download the official OCR A Level Physics A H556/02 Exploring Physics mark scheme from the June 2025 examination series. This downloadable PDF contains the complete examiner mark scheme for OCR A Level Physics A Paper 2, including worked calculations, graph-analysis guidance, uncertainty evaluation, practical-investigation criteria, level-of-response marking, and official OCR examiner annotations used during live marking.

The OCR H556/02 June 2025 mark scheme covers major A Level Physics A topics including potential-divider circuits, semiconductors, charge-carrier density, electron diffraction, wave-particle duality, photoelectric effect, X-ray production, attenuation coefficients, radioactive decay, PET scanning, destructive interference, Young double-slit diffraction, coherence, polarisation, electromagnetic induction, transformers, capacitors, dielectric materials, resistivity, and experimental uncertainty analysis.

Section A contains the official answers for all multiple-choice questions, covering electricity, quantum physics, particle physics, waves, medical imaging, and practical Physics concepts tested in the June 2025 series. The mark scheme clearly identifies the correct options used during OCR examiner marking.

The mark scheme provides extensive worked solutions for electricity and electronics questions involving potential dividers, LED circuits, semiconductors, capacitor charging, dielectric calculations, induced emf, transformer power calculations, and resistivity experiments. Students can see exactly how OCR awards compensatory method marks, accuracy marks, graph-analysis credit, and practical-evaluation marks for multi-stage Physics calculations.
Advanced quantum and particle-physics sections include official examiner guidance for wave-particle duality, electron diffraction, photoelectric-effect evidence, X-ray generation, radioactive decay equations, PET scanning, and attenuation calculations. The mark scheme demonstrates how OCR assesses extended evaluative answers involving experimental evidence, photon theory, particle interactions, and modern Physics reasoning using structured level-of-response criteria.

Waves and electromagnetism sections include official examiner solutions for destructive interference, diffraction fringes, coherence, polarisation, electromagnetic induction, magnetic flux linkage, transformer calculations, and alternating-wave analysis. Students can use the mark scheme to understand how OCR assesses calculations, graphical interpretation, practical methods, and scientific explanations.

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

This OCR A Level Physics A Exploring Physics mark scheme is ideal for understanding examiner expectations, improving advanced calculation accuracy, refining practical-evaluation skills, and mastering AO1 knowledge, AO2 application, and AO3 analytical techniques required for top-band A Level Physics responses. Pair this mark scheme with the matching OCR H556/02 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 A Level Physics students preparing for the 2026 OCR examination series, resit candidates improving Exploring Physics exam technique, home-educated learners, and independent candidates studying OCR A Level Physics A. It is especially valuable for students practising advanced calculations, graph interpretation, uncertainty analysis, modern-physics reasoning, practical evaluation, 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.
