Choosing your Year 12 subjects is one of the most consequential decisions you will make during high school. The right combination can set you up for a strong ATAR and a smooth path into your preferred university course. The wrong combination — often chosen for the wrong reasons — can make your final year unnecessarily stressful.
Pick Subjects You Genuinely Enjoy
This might sound obvious, but it is the single most important piece of advice. You are going to spend hundreds of hours studying these subjects over the next year or two. If you hate a subject, it will be incredibly difficult to stay motivated, and your performance will suffer as a result.
Students who enjoy their subjects tend to study more willingly, engage more deeply with the material, and ultimately achieve higher marks. Passion is a genuine academic advantage.
Understanding How Scaling Works
Scaling exists because not all subjects are equally difficult. If a cohort of strong students tends to choose a particular subject, the raw scores in that subject will be adjusted to reflect the higher ability of that group. Similarly, if a subject attracts a broader range of students, scores may be adjusted differently.
The key point is this: scaling adjusts for the difficulty of the subject and the strength of the cohort, not for how “prestigious” a subject is. It is a statistical process designed to make comparisons fair across different subject combinations.
The Scaling Trap
Every year, students fall into the same trap: they choose subjects purely because they have heard those subjects “scale well.” They drop subjects they love in favour of ones they think will give them a numerical advantage.
This strategy almost always backfires. A high mark in a subject that scales modestly will almost always contribute more to your ATAR than a mediocre mark in a subject that scales generously. Scaling rewards those who do well — it does not rescue those who struggle.
If you are genuinely strong in a high-scaling subject and enjoy it, by all means take it. But if you are choosing it solely for the scaling benefit while dreading every lesson, you are likely hurting your ATAR rather than helping it.
Balance Difficulty and Strengths
Think honestly about where your strengths lie. Are you a strong writer or more numerically minded? Do you thrive in subjects with creative components, or do you prefer structured problem-solving? Choose a combination that plays to your abilities while still meeting any prerequisite requirements for the university courses you are considering.
It is also worth having a mix. Studying five very content-heavy subjects can be overwhelming. Balancing analytical subjects with practical or creative ones can help manage your workload and keep you engaged throughout the year.
Talk to People Who Know
Speak with your teachers, school careers advisor, and students who have recently completed Year 12. They can offer insights into workload expectations, assessment styles, and how different subjects fit together. Make an informed decision rather than relying on rumours or outdated advice.
Your subject choices should reflect who you are and where you want to go — not what someone on the internet told you scales the best.
