### Overview

The Year 12 Algebra and Modelling program is aligned with the content outlined in the Australian curriculum for General Mathematics. Students studying Algebra and Modelling apply algebraic skills and techniques to enhance their ability to interpret and use linear and non-linear mathematical models in a range of contexts.
