WACE Biology Past Papers (Science)
WACE Biology is examined in a single written ATAR paper worth 50% of your final result, set and marked by SCSA, covering ecosystems and the flow of energy and matter, and evolution and biodiversity.
SCSA keeps a rolling window of recent past ATAR exams online - roughly the six most recent years - so there's a compact set to work through, and each one is worth sitting to time.
Official Biology ATAR exam papers & marking keys (2020–2025)
SCSA publishes the past ATAR course exams, the marking keys and the summary examination reports for Biology on its own site. They are the real exam questions - sit them under timed conditions, then mark with the marking key.
What's on the Biology exam?
The paper mixes multiple-choice, short-answer and extended-response questions on the Year 12 content - ecosystem dynamics, population and community ecology, and the mechanisms and evidence of evolution. It rewards data interpretation and well-structured evaluative responses.
The past papers are the best way to rehearse the extended-response and data questions under time.
How to use the past papers
Sit each Biology paper under exam timing, closed-book, then mark it against SCSA's marking key for that year - the key shows exactly how marks are allocated, which is where the improvement comes from.
Finish with the summary examination report for that year: it's SCSA's examiner feedback on what the state cohort did well and badly. The paper, the marking key and the report all download from the official SCSA page linked above.
