How many subjects can you study to get an atar score?

The number of subjects you study to get an ATAR score varies depending on the state and educational system. There's no single answer. Generally, you need to complete a sufficient number of subjects to meet the requirements of your state's tertiary entrance ranking system. This usually involves a minimum number of subjects studied over a period of years (typically two), often including specific subject categories (like English). Each state and territory in Australia has slightly different rules. You need to check the specific requirements for the state where you are studying.
