Pearson Edexcel A-Level Biology Past Papers & Mark Schemes

This archive contains 127 resources from the Pearson Edexcel legacy modular A-Level Biology specification (units 6BI01 to 6BI06), which was the predecessor to the current linear Biology A and Biology B specifications. Students currently studying Edexcel biology should refer to the Biology A (Salters-Nuffield) or Biology B pages for current-specification papers — but these legacy papers remain valuable revision tools because the underlying biology is the same. The legacy specification was divided into six units. Unit 1 (Lifestyle, Transport, Genes and Health) covered biological molecules, the structure of DNA and protein synthesis, cell membranes, exchange surfaces, and the cardiovascular system. Unit 2 (Development, Plants and Environment) examined photosynthesis, ecology, classification, biodiversity, and plant biology. Together, Units 1 and 2 formed the AS Level qualification. Unit 3 was an internally assessed practical unit testing experimental skills — planning, implementing, and evaluating investigations — and is reflected in the archive through practical assessment guidance rather than written papers. Unit 4 (The Natural Environment and Species Survival) covered respiration, photosynthesis in greater depth, homeostasis and excretion, coordination (nervous and hormonal), and inherited change. Unit 5 (Energy, Exercise and Coordination) addressed cellular respiration, muscle contraction, the brain and nervous coordination, and a synoptic Scientific Article assessment. Unit 6 was a further practical unit assessed internally. The Scientific Article papers are a notable feature of this archive — students were provided with a research article before the exam and then assessed on their ability to evaluate the scientific content, methodology, and conclusions. These papers develop transferable analytical skills valuable across all biology specifications.
