How should students prepare for the Australian Science Olympiads?
Preparation runs in three stages: build a solid foundation, then learn by topic and question type, then mock exam and targeted practice.
Build a solid foundation
Make sure the core school skills behind this competition are stable before moving into harder questions.
Learn by topic and question type
Practise the topic patterns and question types that appear most often in this competition.
Mock exam and targeted practice
Use timed mocks to find weak areas, then practise those exact topics deliberately.
Which subject should my child choose?
Biology suits students who enjoy systems, cells, genetics and ecology. Chemistry suits students comfortable with atoms, bonding, reactions and quantitative reasoning. Physics suits students who enjoy mathematical modelling, motion, forces, energy and circuits. Earth and Environmental Science suits students who enjoy Earth systems, geology, climate and environmental data.
