OCR GCSE Gateway Science - Biology A - J247 Past Papers

An analysis of the June 2024 OCR Gateway GCSE Biology J247/03 and J247/04 Higher Tier papers, showcasing a balanced distribution of mathematical skills, experimental design, and core biological understanding with a distinct focus on genetics, protein synthesis, and ecological monitoring.

The June 2023 OCR GCSE (9–1) Biology A (Gateway Science) series presented a balanced assessment across both tiers. Paper 1/3 (topics B1–B3) featured strong coverage of cell transport, enzymology, hormonal control of the menstrual cycle/IVF, and cardiovascular physiology. Paper 2/4 (topics B4–B6) placed substantial emphasis on ecological sampling, selective breeding vs. natural selection, genetic engineering in aquaculture, and mathematical calculations including percentage changes and scale readings.

The June 2022 OCR GCSE Biology A (Gateway Science) series presented a well-balanced assessment across both tiers. Core themes heavily emphasized practical experimental methodology (such as enzyme action with phenolphthalein, potometer transpiration setups, quadrat sampling, and compost respiration), endocrine control and homeostasis (thermoregulation, hormone replacement therapy, and diabetes), and molecular genetics/inheritance. Mathematical applications were prominent, requiring calculations of rates, percentage changes, ratios, and standard form conversion.
