Biology Topics — WACE
WACE Biology ATAR Year 12 is structured as Unit 3 Continuity of Life on Earth (heredity, gene regulation, changes in a population's genetic makeup) and Unit 4 Surviving in a Changing Environment (homeostasis, infectious disease). These units are externally examined and contribute to your ATAR. Revizi also surfaces Year 11 Unit 1 Ecosystems & Biodiversity as foundational revision.
Browse flashcards and quizzes for each WACE Biology topic below, aligned to the SCSA syllabus. Active recall through flashcards builds stronger memory pathways than passive study, helping you perform better in exams.

What topics are in WACE Biology Units 3 & 4?
Unit 3 Continuity of Life on Earth covers heredity, gene regulation and changes in a population's genetic makeup (evolution). Unit 4 Surviving in a Changing Environment covers homeostasis and infectious disease. All are externally assessed in the WACE exam.
How should I revise for the WACE Biology exam?
Use flashcards to memorise key biological processes, terminology, and immune responses. Space your revision across weeks rather than cramming. Practise past WACE questions to get familiar with the exam format.
Are WACE Biology flashcards on Revizi free?
Yes. All WACE Biology flashcards and quizzes on Revizi are free to start, aligned to the SCSA course outline. Upload your notes for custom flashcards, and upgrade to Pro for higher limits.
