Best QCE Subject Combinations for a High ATAR

Choosing your QCE subjects is one of the biggest decisions you'll make in senior school. It affects your ATAR, your university options, and — let's be honest — how much you enjoy the next two years.

So how do you pick the right combination?

The golden rule: play to your strengths

Before we dive into specific combinations, here's the most important thing to remember:

Pick subjects you're good at and enjoy. You'll always score higher in a subject you're engaged with.

Scaling can nudge your ATAR up or down, but your raw performance is the biggest factor. A subject result of 23 in a lower-scaling subject will beat a 17 in a higher-scaling one every time.

Understanding the five-subject rule

Your ATAR is calculated from your best five General subject results (or equivalent Applied/VET combinations). Most students take six subjects so they have a buffer — if one subject doesn't go well, it drops out of the calculation.

Subject combinations that work well

Here are some common pathways and why they work:

The STEM-heavy combination

Specialist Maths, Mathematical Methods, Physics, Chemistry + 2 others

This combination tends to scale well because the student cohort is strong. If you're genuinely strong in maths and science, this is a powerful lineup. But it's demanding — make sure you have the foundation.

The balanced combination

Mathematical Methods, Chemistry or Physics, English, a Humanities subject + 2 others

This keeps your options open for most university courses. Methods is a prerequisite for many STEM degrees, while the humanities subject can provide variety and a different type of thinking.

The humanities-focused combination

English, Legal Studies, Modern History, Psychology + 2 others

Don't believe the myth that humanities subjects all scale badly. Strong students in these subjects still achieve high ATARs. The key is the quality of your work and the strength of your cohort at your school.

What about prerequisites?

Some university courses require specific subjects regardless of your ATAR. For example:

• Engineering typically requires Mathematical Methods (and sometimes Specialist Maths)
• Medicine usually requires Chemistry
• Education degrees vary widely — check the specific university

The scaling trap

Some students try to "game" the system by choosing subjects purely for their scaling advantage. This rarely works:

1. You'll perform worse in a subject you don't enjoy or aren't naturally good at
2. Scaling fluctuates year to year — it's based on the current cohort, not historical data
3. Motivation matters — two years is a long time to study something you hate

How to actually decide

Here's a practical framework:

1. List your prerequisites — which subjects does your target course require?
2. Identify your strengths — where do you consistently perform well?
3. Consider workload balance — don't stack all assignment-heavy or all exam-heavy subjects in one semester
4. Talk to your teachers — they can give you honest feedback about whether a subject suits you
5. Use data — tools like Thynkr can show you how different subject combinations might affect your ATAR

The bottom line

There's no single "best" combination. The best subjects for you are the ones where you'll perform well, meet your prerequisites, and maintain your sanity over two years of senior school. Use scaling data as one input, not the only input.
