QCE Biology Past Papers (Sciences)
QCE Biology external assessment is worth 50% of your final result — the Science EA band — and is examined across two papers combining multiple-choice and short-response questions.
QCAA introduced external assessment with the current QCE system in 2020, so there are only a handful of past papers per subject — which makes each one worth sitting properly under timed conditions.
What's on the Biology exam?
The EA covers Units 3 and 4 — biodiversity and the interconnectedness of life, and heredity and continuity of life (cellular respiration and photosynthesis, DNA and gene expression, inheritance, natural selection and evolution). Questions test both recall and the ability to interpret data and unfamiliar scenarios.
At 50% of your result, the external exam is worth as much as all your internal assessment, so timed past-paper practice matters.
How to use the past papers
Sit each paper to time, mark it against the QCAA marking guide, then read that year's subject report — for Biology the report is particularly good at showing how to structure data-analysis and evaluation responses, where marks are most often left on the table.
The papers, marking guides and subject reports download from the Resources section of the official syllabus page linked above.
