This document provides advice on selecting HSC subjects and understanding the ATAR. It discusses four key considerations: workload, choosing subjects you enjoy and excel in, university prerequisite requirements, and how subject scaling affects ATAR calculations. The document recommends aiming for 11-12 subjects, with at most 2 major works, and choosing the highest-level maths and English subjects that you can handle. Students should select subjects they love and are interested in to stay motivated while also considering assumed knowledge for their intended university programs. English Advanced is generally better than Standard due to scaling. With an understanding of these factors, students can make informed choices about their HSC subjects.
