OCR AS Level Biology A - H020 Past Papers
Browse past paper analysis, answer explanations, grade boundary estimates, and thinka-original sample papers by subject and year.
Available years: 2025, 2024, 2023, 2022
The June 2025 H020 set comprises Breadth in biology and Depth in biology: 140 marks in 180 minutes. Overall demand is moderate, with accessible recall and completion marks balanced by practical evaluation, precise explanations and two extended responses. Classification, cell division and exchange surfaces lead the biological primary-topic allocation. All 77 independently marked parts are mapped without double counting. Insights are inferred from the mark schemes; no examiner-performance report is attached.
The 2024 OCR AS Level Biology A exam series consists of H020/01 (Breadth in Biology) and H020/02 (Depth in Biology). This series presents a balanced test of theoretical recall and practical experimental application, with an increased focus on quantitative mathematical skills and the evaluation of scientific methodology.
The June 2023 OCR AS Level Biology A (H020) series comprises H020/01 (Breadth) and H020/02 (Depth), presenting a balanced mix of fundamental recall, demanding practical-experimental design questions, and mathematical calculations including uncertainty and Spearman's rank.
The June 2022 OCR AS Level Biology A papers (H020/01 and H020/02) present a challenging assessment of fundamental biology, prioritizing biochemistry, cellular transport, and practical design. Key differentiators included mathematical calculations of surface area, rate of osmosis, and genetic polymorphism indices, alongside rigorous extended-response questions on membrane permeability.
