Official curriculum and assessment

To start WACE Human Biology revision, open the 2025 examination paper (PDF). Use the official resources below to choose a task, attempt it independently and check your response against the available assessment guidance. The practice sequence below explains how to turn that review into a focused next attempt. Confirm the paper’s course and syllabus year before using it.

How to practise this subject

These practice suggestions are editorial guidance from Australian Study Resources.

  1. Choose a current course task with this focus: endocrine glands, their hormones and target organs. Draw a labelled process diagram and explain the role of each structure or stage. Use arrows to show a causal sequence.
  2. Choose a current course task with this focus: divisions of the nervous system: central–peripheral, afferent–efferent, autonomic–somatic, sympathetic–parasympathetic. Identify a measurable variable and an appropriate comparison. Explain how one specific control reduces an alternative explanation.
  3. Choose a current course task with this focus: nervous versus endocrine control and the principles of homeostasis (feedback, tolerance limits). Describe a pattern in data with values and units. Explain a plausible biological mechanism while keeping the conclusion within the evidence.
  4. Record the specific point you missed, write a corrected response, and attempt another question that requires the same skill. Check older material against your current course before reusing it.

Plan your next practice session

Choose one explanation from your practice sequence. Separate what was observed from the explanation you propose, then identify a condition or limitation that affects the conclusion.

How to explain scientific results without overstating them — includes an original example and a downloadable worksheet.
