About AUS-e-TUTE

AUS-e-TUTE is an interactive learning resource being developed by experienced science teachers to provide free tutorials suitable for high school students.
Every AUS-e-TUTE tutorial is a single page explanation of a particular scientific concept written in easy to understand language suitable for high school students.
Each tutorial page has links to tests, exams and games, which are only available to AUS-e-TUTE members. Fully worked solutions are provided for all AUS-e-TUTE test and exam questions.
New games, test and exam questions are added to the Members Only Test Centre regularly.
