Year 11 and Year 12 planning

Compare Units 1-2 and Units 3-4 coverage so practice can match the student's current course stage.

WA senior Biology is organised by Units 1-4, with Units 1-2 in Year 11 and Units 3-4 in Year 12.

Biology is a WACE ATAR science course with conceptual understanding, biological systems modelling, diagram interpretation, fieldwork data evaluation, uncertainty analysis, and scientific inquiry requirements.

The WACE Biology pathway below is aligned with publicly available SCSA syllabus information and organised for targeted practice planning.
