CR GCSE Chemistry A (Higher Tier) – Paper 3: Question Paper (J248/03) – 2025

This question paper assesses students’ understanding of the core and intermediate chemistry concepts in the OCR GCSE Chemistry A (9–1) specification at Higher Tier level, focusing on application, calculation, and scientific reasoning.

Paper 3 covers content from the first half of the specification, including:

Atomic structure and the periodic table – subatomic particles, electronic structure, and periodic trends
Bonding, structure, and properties of matter – ionic, covalent, and metallic bonding, and material properties
Quantitative chemistry – mole calculations, equations, concentrations, and gas volumes
Chemical changes – acids, alkalis, salts, electrolysis, and reactivity series
Energy changes – exothermic and endothermic reactions and reaction profiles

The paper includes multiple-choice questions, short-answer questions, structured questions, calculations, practical-based questions, and extended responses, requiring students to apply chemical knowledge to both familiar and unfamiliar contexts.

This question paper is ideal for exam practice, mock assessments, classroom teaching, and independent study, helping students become familiar with exam structure, command words, and Higher Tier exam techniques.
