OCR GCSE Biology B (Higher Tier) – Paper 3: Topics B1–B3 (J257/03) + Mark Scheme (2025)

This paper assesses students’ understanding of the core biological principles in the OCR GCSE Biology B (9–1) specification, with an emphasis on applying knowledge, analysing data, and using scientific methods.

Paper 3 covers Topics B1 to B3, which include:

B1: Cell-level systems – cell structure, microscopy, transport in cells, and cell division
B2: Scaling up – organisation of organisms, tissues, organs, organ systems, and transport systems
B3: Organism-level systems – digestion, respiration, circulation, plant transport, and homeostasis

The exam features a mix of multiple-choice questions, structured questions, calculations, practical-based questions, and extended responses, requiring students to demonstrate both knowledge and scientific reasoning at Higher Tier level.

The accompanying mark scheme includes:

Detailed marking points for each question
Accepted alternative answers
Guidance for calculations and graph-based questions
Level-of-response criteria for longer answers

This resource is ideal for exam preparation, mock assessments, teacher revision sessions, and independent study, helping students improve exam technique and understand how to maximise marks.
