Picking your VCE subjects: a guide that actually helps

Most subject-selection advice I read online is one of two flavours. Either someone telling you to pick what you love, or someone telling you to pick what scales. Both are missing the point. The right line-up is the one that, in November of Year 12, gives you the highest aggregate you can realistically reach.

That's what we'll work through here.

The actual goal

Your aggregate is built from your top four scaled scores plus 10% of your 5th and 6th. Read How the ATAR works if that doesn't ring a bell yet. The aggregate-to-ATAR table doesn't care which subjects produce those numbers. It cares about the numbers.

So the question isn't "what subjects scale up" or "what subjects are easy". It's:

Which six subjects, given my ability and my appetite for work, give me the highest predicted aggregate?

That's a search problem. The four big inputs:

1. What you're already good at.
2. What you can stay engaged with for two years.
3. The scaling for the subject (how raw → scaled converts).
4. Prerequisites for what comes after Year 12.

In rough order of importance for most students.

What you're already good at

Your raw study score is mostly determined by where you rank in your class and how you do on the exam. Both of these correlate with how good you already are at the subject going in.

Picking Specialist Maths because it scales up, but you've never been near the top of a maths class, is a way to lose 5 ATAR points. The scaling lift is real, but landing at raw 27 in a subject that scales up is worse than landing at raw 38 in a subject that scales down.

A simple test: in your Unit 1/2 of any subject you're considering, where did you rank? If you were top half consistently, the subject is on the table. If you were bottom half, you'd need a clear reason to pick it for 3/4.

Engagement and energy

Two years is a long time. Year 12 will eat your weekends.

Subjects you actively dislike take 1.5–2× the study time to land the same mark, because you procrastinate, you forget, you don't read past the page you're on. Subjects you find interesting compound: you read past the syllabus, you remember things you weren't taught, exam questions feel less foreign.

This is unsexy, hard-to-quantify advice. It's also the single biggest predictor of where students underperform their potential.

If you're choosing between two subjects with similar prereqs and similar scaling, pick the one you'd voluntarily read about on a Sunday.

Scaling

Read How VCE scaling works if you haven't. Quick version: the published 2025 anchors for popular subjects:

Things to notice:

• A raw 35 in Methods scales the same as a raw 38 in Biology. That's roughly half a unit of effort difference for the same aggregate contribution.
• The "scale-up" group flattens above 45. Past raw 45, almost everything maps to mid-50s scaled. The lift comes in the middle, not at the top.
• The "scale-down" group still hands out 50s for raw 50s. The penalty is in the middle, not the top.

Prereqs and pathways

Engineering needs Methods, almost universally. Most science degrees need Chemistry. Architecture pathways often want Methods. Medicine wants strong Methods + Chemistry + sometimes Biology. Most arts and humanities degrees have very few prereqs.

Two failure modes I see every year:

1. Picking subjects that don't unlock the pathway you want. "I want to do biomedicine but I'm dropping Methods" is a real conversation a lot of Year 11s have. Don't.
2. Loading up on prereqs you don't need. "I'm doing Chemistry, Biology, and Physics in case I do something STEM." That's three lab subjects competing for your weekend revision time. Pick the two you're best at.

Use your university's prerequisite tool. VTAC Course Search is the canonical one. Most courses have prereqs that are short and specific.

How many subjects?

Five gives you enough safety margin. Six gives you the 10% increment slot to play with. Seven mostly costs you raw scores in your primary four.

The maths: a 6th subject scaled at 30 contributes 3.0 to your aggregate, worth ~0.6 of an ATAR point at the 90 line and less at the higher end. That 6th subject costs you ~5 hours/week of study during peak revision. If five hours/week of study would lift one of your primary-four subjects by a single raw point, that's almost always a better deal.

Take the 6th subject if:

• You're confident it'll scale at 35+ (so the 10% is at least 3.5)
• You enjoy it enough that it doesn't significantly cut into your other revision time
• You need it for a prerequisite

Don't take a 6th "just in case." That's almost always a worse aggregate than five well-prepared subjects.

A worked example

Hypothetical student. Strong in maths and chem, decent at English, hates languages, likes psychology. Considering eight options. Final picks I'd back:

1. English (compulsory)
2. Methods (strong already, scales well)
3. Chemistry (strong, prereq for biomed)
4. Specialist Maths (only if Methods is at 90+ in unit 1/2)
5. Psychology (engagement matters)

That's five. A 6th could be Biology if it lifts the medicine application; otherwise leave it.

Notice what's not in the list: a "scale up" pick for the sake of scaling, or two languages because someone said languages scale.

Mistakes to avoid

Picking a subject because someone else dropped a 47 in it. Different student, different cohort, different context. Their result is irrelevant to yours.

Picking only "scale up" subjects. If your six subjects are all in the academically strong cohorts, you're competing against the strongest students in the state in every single one. There's no recovery subject.

Picking only "easy" subjects. Same problem in reverse. You'll cap your aggregate at whatever the scaled-down subjects' top contributors are.

Locking in subjects in Year 10 with no review. Your interests will change. So will your relative ability. Re-evaluate at the end of Unit 2.

Listening to your school's "this subject is doable" advice without checking the school's exam history. Schools differ. A subject that's doable at one school is brutal at another, depending on the teacher and the cohort.

What to do this week

1. List every subject you're considering. Include the long-shots.
2. For each: be honest about where you ranked in Unit 1/2, and how engaged you actually were.
3. Run two scenarios in the ATAR Calculator — your best-case raw scores and your realistic raw scores.
4. Look at the difference. The difference is what you should optimise.

The goal of this whole exercise: a line-up where your realistic aggregate is high enough to clear the courses you want, with one subject of slack.
