Biology. All Assessment Questions & Mark Scheme [OCR J247/04]
Exam Resource Summary
The GCSE (9–1) Biology A (Gateway Science) June 2025 Higher Tier Paper (OCR J247/04) is a fully
integrated resource that merges the complete official examination paper with its corresponding mark
scheme. This combined format enables students to understand not only the scope of content assessed—
cell biology, genetics, ecology, health and disease, bioenergetics, and biological interactions—but also the
precise expectations behind each question. The paper assesses a wide range of skills, including the
application of scientific knowledge, interpretation of data, analysis of experimental scenarios, and
evaluation of biological ideas with clear reasoning. The included mark scheme offers explicit guidance on
command words, required scientific detail, and the distinctions between lower-, middle-, and higher-tier
responses. By integrating questions and marking criteria side-by-side, this resource supports effective
revision, enhances exam technique, and helps learners develop accurate, well-structured answers. It
provides a complete and reliable tool for preparing for the 2026 OCR GCSE Biology A (Gateway
Science) Higher Tier examination.
