Official Human Biology ATAR exam papers & marking keys (2020–2025)
SCSA publishes the past ATAR course exams, the marking keys and the summary examination reports for Human 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 Human Biology exam?
The paper combines multiple-choice, short-answer and extended-response questions on the Year 12 content - the nervous and endocrine systems, the immune system, DNA and inheritance, and human evolution. It rewards the ability to interpret data and diagrams and to build a structured extended response.
Working the past papers is the best way to practise the data-interpretation and extended-response questions where marks are most often lost.
How to use the past papers
Sit each Human 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.
