The envelope arrives home in your Year 10’s school bag and your heart skips a beat. Subject selection time. Suddenly, every conversation with other parents becomes a minefield of comparisons and second-guessing. Should they keep Chemistry even though they’re struggling? Will dropping Advanced Maths ruin their chances at university? And why does everyone else seem so confident about their choices when you’re lying awake at 2am wondering if your child is about to accidentally sabotage their future?
Take a deep breath. Despite what the school gate whispers might suggest, there’s no single “right” combination that guarantees success, and no “wrong” choice that permanently derails dreams. The pressure you’re feeling is real, but the stakes aren’t quite as high as they seem. While these choices are important, they’re far less final than they feel right now – and recent research reveals some surprising truths about what actually predicts university success.
One comprehensive study on this topic comes from the Universities Admission Centre’s research on “The Impact of Senior Secondary Study Choices on Success at University.” Their findings should reassure anxious parents: ATAR is one of the strongest predictors of first-year university success, explaining about 21.5% of the variance in university grades.
What does this mean practically? Your child’s overall academic performance across all their subjects matters much more than whether they choose the “right” combination. A student with a strong ATAR from subjects they excel in will typically outperform a struggling student who forced themselves through subjects they thought were “better” choices.
Dr Sarah Mitchell, a university admissions expert from the University of Sydney, adds: “Universities have become increasingly flexible about prerequisite subjects. While some courses still require specific subjects, there are usually alternative pathways available.”
The UAC research reveals that while ATAR dominates, certain subject choices do provide advantages in specific university fields:
For Science Degrees: Students who studied 1-3 HSC science subjects (Physics, Chemistry, Biology) showed measurably higher first-year university grades in Natural and Physical Sciences courses. The preparation matters.
For Engineering: Mathematics (particularly calculus-based Mathematics or Extension courses) correlates with better performance and significantly lower failure rates. This isn’t just correlation – the mathematical foundation genuinely helps students succeed.
For Education Degrees: The research flagged concerning gaps, with many Education students entering university without advanced English or any science/mathematics background, raising questions about their preparedness for teaching these subjects.
However, the key finding remains: once ATAR is accounted for, subject choice adds less than 1% additional predictive power for university success in most fields.
Here’s where the research gets really interesting for Year 10 families. Students who studied subjects across more Key Learning Areas (KLAs) – essentially a broader curriculum – showed higher university grades, lower dropout rates, and better subject pass rates.
This finding challenges the common parent worry about “focus” and “specialization.” The research suggests that studying English, Mathematics, a science, a humanities subject, and perhaps a creative or practical subject creates better-prepared university students than narrow specialization in Year 11-12. Why? University first-year courses often span multiple disciplines, requiring diverse thinking skills that a broad high school curriculum develops.
Maths deserves special attention based on this research. While not every career requires advanced maths, the UAC study confirms that calculus-based mathematics provides genuine advantages for STEM university courses. However, the Australian Mathematical Sciences Institute research indicating that students who discontinue mathematics limit their access to 75% of university courses should be viewed alongside the UAC finding that students generally self-select appropriate university pathways.
Most students intuitively choose university courses aligned with their HSC strengths. The research found that a machine learning model could accurately predict suitable university fields for 36% of students – and those who followed these data-driven recommendations had higher grades and lower dropout rates.
The obsession with which subjects “scale better” for ATAR calculations needs reframing based on this research. Yes, certain subjects (higher-level Mathematics, English Advanced, Physics, Chemistry) tend to yield higher scaled marks – but this is largely because they’re typically chosen by higher-performing students who would achieve strong ATARs regardless. In reality, a student getting a score of 85 in Art will almost always achieve a better ATAR outcome than the same student struggling to 65 in Physics because they thought it would scale better. The UAC research supports this – ATAR strength matters far more than which specific subjects contributed to that ATAR. Unsure about ATAR? The University of Sydney’s handy ATAR Explained article is a good starting point.
Based on the UAC findings, here’s how to approach subject selection strategically:
✅ Prioritize ATAR strength. The research is clear – help your child choose subjects where they can achieve their highest grades. Their overall ATAR will predict university success far better than any specific combination.
✅ Maintain breadth across Key Learning Areas. The data shows students benefit from studying across multiple disciplines. A combination spanning English, Mathematics, Science, Humanities, and perhaps Creative Arts or Languages creates better-prepared university students.
✅ Consider specific prerequisites only for STEM fields. If your child is genuinely interested in Engineering, advanced Mathematics preparation helps. For Science degrees, having some HSC science background provides measurable advantages. But for most other fields, the subject-specific preparation matters much less than strong overall performance.
✅ Trust your child’s interests and strengths. The research confirms that students generally choose appropriate university pathways based on their high school strengths. Fighting against their natural inclinations rarely improves outcomes.
The fastest-growing careers often don’t map neatly onto traditional subject combinations, but the UAC research suggests this matters less than we think. LinkedIn’s 2023 Future of Work Report identifies that employers increasingly value “hybrid skills” – combinations like technical knowledge with communication abilities, or creative thinking with analytical skills.
The UAC finding that broader subject combinations create more successful university students aligns perfectly with these workplace trends. Your child’s diverse subject selection might actually advantage them in tomorrow’s job market.
Rather than directing your child’s choices, facilitate their decision-making with research-informed questions:
Inner West high schools typically offer subject selection interviews with career advisors in Term 3. Take advantage of these – school counsellors understand both the research on university success and your child’s specific academic profile.
