What If You Do Not Know What You Want to Study After School?

Your Year 10 subject selection form is asking you to make decisions about the next two years. But you don’t know whether you want to study science, law, engineering, business, design, or something you haven’t even heard of yet.

So how are you supposed to choose?

The good news is that you don’t need to know exactly what you want to study after school. You need a subject combination that reflects what you enjoy, plays to your strengths, and keeps a reasonable range of future options available.

The trick is to avoid two opposite mistakes: choosing subjects randomly because you have no career plan, or choosing every supposedly difficult subject because you are afraid of closing a door.

Neither is a particularly good strategy.

Instead, work through a few practical checks. You’ll have a much clearer idea of what to choose, even if your future plans are still uncertain.

01You don’t need to choose your career yet

There is a difference between knowing what interests you and knowing exactly what you want to do for a living.

You might enjoy solving mathematical problems without knowing whether you want to become an engineer, economist, programmer, or mathematician.

You might enjoy biology without knowing whether you want to work in healthcare, environmental science, research, or something completely different.

That’s perfectly reasonable.

At this stage, think about your HSC subjects as a toolkit. You want a useful collection of skills and knowledge that supports several possible directions.

You don’t need every tool in existence. You need the ones that are useful for the paths you’re considering.

There is one important limitation to this analogy: some university courses have formal subject prerequisites. If a degree requires a particular HSC subject and result, simply being interested in that degree won’t replace the requirement.

That’s why your decisions need to consider both personal preference and future study requirements.

02Start with what you actually enjoy

Before researching university degrees, look at your current school subjects.

Forget about career titles for a moment. Think about the actual work you enjoy doing.

For example:

• Do you enjoy solving unfamiliar problems, working with equations, and finding patterns?
• Do you prefer understanding how living systems work?
• Are you interested in experiments, chemical reactions, and explaining physical phenomena?
• Do you enjoy writing arguments, analysing historical events, or discussing social issues?
• Do you like designing things, creating visual work, or building practical projects?
• Do you enjoy understanding how businesses, economies, and organisations operate?

These questions are more useful than asking yourself whether you want to become a doctor, lawyer, or engineer.

A job title tells you very little about whether you’ll enjoy the subjects involved in getting there.

Look at your performance as well as your interests

Enjoying a subject is important, but you also need to consider whether you’re prepared for its academic demands.

Suppose you enjoy mathematics but consistently struggle with algebra. That doesn’t automatically mean you should avoid Mathematics Advanced. It does mean you should speak with your teacher about the foundations you’ll need and whether you’re ready for the next level.

Likewise, getting a high mark in a subject doesn’t necessarily mean you enjoy studying it enough to continue for another two years.

Look for patterns rather than relying on one assessment result.

Consider:

You don’t need to be excellent at every subject you choose. You do need a realistic understanding of what each course will demand.

03Keep a few possible pathways open

Once you’ve identified your interests, think about two or three possible directions you could explore after school.

These don’t need to be specific careers.

You might consider:

• Science and health.
• Engineering and technology.
• Business, economics, and finance.
• Law, humanities, and communications.
• Design, architecture, and creative industries.
• Trades, vocational education, and apprenticeships.

You can investigate several of these without committing to any of them.

For each possible direction, look at actual university degrees, TAFE courses, apprenticeships, or other training options.

One useful technique is to look at the subjects students study in their first year of a university degree.

A degree might sound interesting because of its career opportunities, but its first-year subjects could involve considerably more mathematics, chemistry, writing, or programming than you expected.

That’s useful information to have before choosing your HSC subjects.

UAC also recommends exploring different study options, attending university open days, and speaking with careers advisers when you’re unsure about your future.

Its Year 10 and 11 subject-planning guidance is a useful starting point.

04Understand which subject requirements actually matter

This is probably the most important part of making a sensible decision.

Not every subject that is useful for a university degree is compulsory for admission. Likewise, a subject that isn’t compulsory for the HSC might still be essential for entering a particular university course.

You need to distinguish between four different things.

1. NESA HSC requirements

The NSW Education Standards Authority (NESA) sets the statewide requirements for completing the HSC.

For the standard Preliminary and HSC patterns of study, students must satisfactorily complete:

These are statewide requirements, not recommendations about which particular subjects you should choose.

For example, NESA does not require every student to study Physics, Chemistry, Biology, or Mathematics Advanced.

You can read the official requirements in the NESA Assessment, Certification and Examination (ACE) Rules.

2. University course prerequisites

A university prerequisite is a formal entry requirement.

It means you must have completed a particular subject to the required standard to be eligible for admission to that course.

For example, the University of Sydney currently requires students applying with an NSW HSC to achieve either:

• Band 4 in Mathematics Advanced; or
• Band E3 in Mathematics Extension 1 or Mathematics Extension 2.

This prerequisite applies to specified degrees, including its engineering and advanced computing courses.

Mathematics Standard does not meet this particular requirement.

This is an important distinction. The mathematics prerequisite is a University of Sydney admission requirement. It is not a statewide NESA requirement for completing the HSC.

You can check the University’s current mathematics prerequisite information.

If a course you’re genuinely considering has a prerequisite, take it seriously. You don’t want to discover in Year 12 that you’ve missed an admission requirement that could have influenced your subject selection.

3. Assumed knowledge and recommended studies

These are different from formal prerequisites.

Assumed knowledge means a university expects you to arrive with a certain level of understanding in a subject.

You might still receive an offer without having studied that subject, but you could find the first-year content considerably harder.

Recommended studies are advice about subjects that may help you prepare for the degree. They are not automatically admission requirements.

For example:

• UNSW states that it does not have formal HSC subject prerequisites for its degrees, but many courses have assumed knowledge. It recommends bridging courses or other preparation if you haven’t studied the relevant subjects.
• UTS does not have HSC subject prerequisites for its courses, although individual faculties may identify assumed knowledge and recommended studies.

These differences are important.

A student who hasn’t studied Physics might still be eligible to apply for an engineering degree at one university, while another course at another institution might have different requirements.

Never assume that every university uses the same admission rules.

You can check the official information at UNSW and UTS.

4. Your school’s requirements and limitations

Your school has its own practical considerations.

It might not offer every HSC course. Some subjects may only run if enough students enrol, while others may clash on the timetable.

Your school might also have internal course-placement recommendations, particularly for Mathematics Advanced and Extension courses.

These are school-level considerations. They are not automatically NESA requirements or university admission prerequisites.

Ask your school:

• Is this subject definitely running next year?
• Does it clash with another subject I’m considering?
• Are there any school-specific course-entry or placement requirements?
• Is the recommended mathematics level compulsory for enrolment, or is it advice?
• Are there alternative arrangements if a course doesn’t run?
• Can I change my subject combination later, and what would I need to catch up?

A course being unavailable at your school doesn’t mean that an entire career pathway is closed. However, you’ll need to investigate whether another approved way of studying the subject is available.

05A practical process for choosing your subjects

Now that you understand the different requirements, you can put them together.

Rather than trying to find the perfect subject combination immediately, work through the following steps.

Step 1: Identify your strongest interests

Write down three to five subjects or areas of learning that genuinely interest you.

Don’t worry about whether they seem related.

For example, you might enjoy:

• Mathematics.
• Biology.
• Visual Arts.
• Business Studies.

That’s a perfectly reasonable starting point.

You don’t need to force these interests into one career category.

Step 2: Identify two or three possible study directions

Look at the subjects you enjoy and consider where they might lead.

For example:

These are starting points, not strict subject-to-career rules.

You can also investigate pathways that don’t require university study.

Step 3: Check the requirements for specific courses

This is where you move from general possibilities to actual information.

Find two or three university courses that interest you and check their admission requirements.

For each one, record:

• Formal subject prerequisites.
• Required HSC results in those subjects.
• Assumed knowledge.
• Recommended studies.
• Other selection requirements.

Don’t just look at the name of the degree.

A Bachelor of Engineering at one university may have different requirements from a similar degree elsewhere.

If you cannot find a formal prerequisite, don’t invent one based on what someone says is normally studied.

Step 4: Choose a balanced combination

You now have enough information to start building a subject pattern.

A sensible combination generally includes three elements:

Subjects that preserve important options.

These are subjects that help you meet genuine admission requirements or prepare for study areas you might pursue.

Subjects that you genuinely enjoy.

You will spend a substantial amount of time studying these courses. Interest matters.

Subjects that suit your demonstrated abilities.

Choose a level of difficulty that challenges you without setting you up for an unnecessarily difficult two years.

You don’t need every subject to serve the same purpose.

For example, you might study Mathematics Advanced because it keeps certain university pathways available, Biology because you enjoy it, and Modern History because you’re interested in understanding society.

That’s a more useful reason for choosing subjects than trying to create a combination that looks impressive on paper.

Step 5: Check the actual school timetable

A subject combination can look excellent in theory and still be impossible at your school.

Check the subject lines before finalising your choices.

If two subjects clash, decide which one has greater value for your likely pathways, interests, and preparation.

Also ask whether an alternative arrangement is possible.

If you’re dealing with a timetable clash, our guide What Should You Do If Two HSC Subjects Clash on the Timetable? explains how to approach the problem.

Step 6: Be realistic about your workload

Choosing a subject because it might be useful is one thing. Choosing five demanding subjects without considering your workload is another.

Think about the type of work involved.

For example:

• Mathematics Extension 1 involves additional mathematical problem-solving and a faster, more demanding level of work.
• Physics involves mathematical modelling, interpreting physical situations, and applying concepts to unfamiliar problems.
• Chemistry involves quantitative work, chemical models, and explaining reactions and patterns.
• History and English require substantial reading, analysis, and written communication.
• Visual Arts involves developing creative work, making decisions about artistic practice, and analysing artworks.

Your subject combination should be challenging enough to develop your abilities, but manageable enough that you can maintain consistent effort.

If you’re unsure about your total unit load, read How Many Units Should You Take in Year 11?.

06Don’t choose subjects just because they scale well

This is a common trap.

You might hear that Physics, Chemistry, or Mathematics Extension 2 scales well, so you should take one of these subjects even if you don’t particularly enjoy it.

The problem is that scaling doesn’t work like a permanent bonus attached to a subject.

UAC calculates scaled marks using the academic performance patterns of students taking each course. These patterns can change from year to year.

Courses that attract students who perform strongly across their subjects often produce higher scaled marks. However, you still need to achieve a strong result yourself.

There is no guarantee that choosing a particular subject will increase your ATAR.

Consider two students:

• Student A chooses Physics because it has a reputation for strong scaling, despite struggling with the subject and having little interest in it.
• Student B chooses a combination of subjects that better matches their strengths and interests, allowing them to work consistently and perform well.

Student A has not automatically made the better decision.

The ATAR calculation uses scaled marks, not the names of the subjects you study. UAC uses your best two units of English and your best eight units from your remaining courses.

You also need to meet the separate ATAR eligibility requirements, including studying at least four subject areas.

For a detailed explanation, read How Your ATAR Is Calculated.

The practical lesson is simple: don’t sacrifice a subject you enjoy and perform well in because another subject has a reputation for scaling better.

07Worked examples: putting the process into practice

Let’s apply the process to two realistic situations.

08Check that you’re using the right syllabus and admission information

Course information changes. This matters particularly when you’re using older HSC study guides or university admission booklets.

The policy information in this article was checked on 8 November 2026.

For students choosing Year 11 subjects in late 2026 and starting Year 11 in 2027, the expected HSC cohort is 2028. Students applying directly to university after completing that HSC would generally be looking at 2029 entry.

The NESA pattern-of-study requirements discussed above come from the ACE Rules last updated on 29 January 2025.

University admission examples require a little more care:

• The University of Sydney’s current mathematics prerequisite information identifies the specific degrees and HSC results that require Mathematics Advanced or an Extension course.
• UNSW’s published 2027 Domestic Undergraduate Guide provides examples of assumed knowledge for 2027 entry. Its Engineering degrees, for example, list Mathematics Extension 1 and Physics as assumed knowledge. This is not a guarantee of the requirements for 2029 entry.
• UTS’s current domestic undergraduate eligibility information explains its policy on HSC prerequisites, assumed knowledge, and recommended studies.

UAC’s currently linked Steps to Uni for Year 10 Students 2026 edition also contains university course information for its listed year. Don’t treat those course tables as guaranteed admission requirements for a later intake.

If you’re planning to enter university in 2029, check the relevant course pages and UAC course listings again when the 2029 entry requirements become available.

A note about the new Physics and Chemistry syllabuses

If you’re choosing subjects for Year 11 in 2027, there is another timing detail worth knowing.

The replacement Physics 11-12 Syllabus (2025) is implemented from 2027. Its first HSC examination will be in 2028.

The replacement Chemistry 11-12 Syllabus (2025), however, is implemented from 2028. Its first HSC examination will be in 2029.

This means a student starting Year 11 in 2027 will study the new Physics syllabus but remain on the existing 2017 Chemistry syllabus throughout their Year 11 and Year 12 courses.

The old Module 1-8 labels belong to the 2017 science courses. Don’t assume they describe the structure of the replacement syllabuses.

Use the correct official course guide for your cohort:

• NESA Physics 11-12 Syllabus (2025)
• NESA Chemistry 11-12 Syllabus (2025)

09Questions and solutions

The following scenarios will help you apply the decision-making process. Some are straightforward, while others require you to consider several competing factors.

Question 1

Ella is in Year 10 and enjoys English, Biology, and Geography. She has no idea what she wants to study after school.

Her friend tells her that she should take Physics because it is a difficult subject that will look good on her HSC record.

What should Ella do before deciding whether to study Physics?

Solution 1

Ella should investigate whether Physics is relevant to any of the university or career pathways she might genuinely consider, rather than choosing it because of its reputation.

She should:

• Identify two or three possible study directions that interest her.
• Find some university courses or vocational pathways within those areas.
• Check whether Physics is a prerequisite, assumed knowledge, or simply recommended.
• Consider whether she enjoys the subject and has the mathematical foundations to manage it.

If Physics is not needed for her shortlisted pathways and she doesn’t particularly enjoy it, there is no automatic reason to choose it.

Her friend’s advice confuses subject difficulty with subject suitability. A challenging course isn’t necessarily a better course for every student.

Question 2

A student is considering two university degrees.

The first degree lists Mathematics Advanced with a minimum Band 4 result as a formal prerequisite.

The second degree lists Physics as assumed knowledge.

The student can only fit one of these subjects into their school timetable.

Their careers adviser says both subjects are required for university study.

Explain why this advice needs to be examined more carefully. Which requirement should the student investigate first?

Solution 2

The Mathematics Advanced requirement is a formal admission prerequisite, while Physics is assumed knowledge for the second degree.

These requirements have different consequences.

Step 1: Investigate the formal prerequisite.

The student must establish whether they can complete Mathematics Advanced and achieve the required Band 4 result.

If they cannot meet the prerequisite, they may not be eligible for admission to the first degree through the standard entry route.

Step 2: Investigate the assumed knowledge requirement.

The second degree expects students to arrive with Physics knowledge.

However, assumed knowledge does not necessarily prevent a student from receiving an offer.

For example, UNSW explicitly states that its assumed knowledge requirements are not formal subject prerequisites. It recommends bridging courses or other preparation to address missing knowledge.

Step 3: Compare the two pathways.

The student should investigate the first degree’s formal entry condition before treating both subjects as equally compulsory.

They should then assess how important Physics preparation is for the second degree and whether a suitable alternative preparation option exists.

Step 4: Check the exact institutions and courses.

The careers adviser’s statement may be useful as general advice, but it is too broad to guide a final decision.

The correct subject combination depends on the actual admission requirements of the courses being considered.

Question 3

A student plans to complete 12 HSC units across six 2-unit Board Developed courses:

• English Advanced.
• Mathematics Advanced.
• Physics.
• Chemistry.
• Biology.
• Modern History.

The student believes that all 12 units must contribute to their ATAR because they have chosen 12 units rather than the minimum 10.

Is this correct? Explain how their ATAR aggregate is calculated.

Solution 3

No. The student’s ATAR aggregate is calculated using 10 units, not all 12.

Under UAC’s current NSW calculation rules, the aggregate includes:

• The best 2 scaled units of English.
• The best 8 scaled units from the remaining courses.

In this example, the student has:

UAC uses the 2 English units and the best 8 of the remaining 10 units.

Therefore, 2 units from the student’s other courses will not contribute to the aggregate.

This selection is based on scaled marks, not simply which courses have the lowest reported HSC marks.

There is also a separate eligibility requirement. The student must have satisfactorily completed at least four subject areas, alongside the other ATAR eligibility conditions.

The 12-unit pattern gives the student additional course capacity, but it does not mean every unit will be included in the ATAR calculation.

Remember that the HSC and ATAR have different purposes. NESA sets the requirements for the HSC credential, while UAC determines ATAR eligibility and calculates the ATAR.

Question 4

Daniel wants to study Chemistry in Year 11 because he is considering science and health-related degrees.

His school informs him that Chemistry might not run next year because too few students have selected it.

Daniel assumes that:

1. NESA requires Chemistry for the HSC.
2. If his school offers another science subject, that subject will automatically satisfy any university Chemistry prerequisite.

Explain why both assumptions are incorrect and outline what Daniel should do.

Solution 4

Neither assumption is correct.

Chemistry is not a compulsory statewide HSC subject, and another science subject does not automatically replace Chemistry when a university has a specific prerequisite.

Step 1: Check the NESA requirements.

The standard HSC pattern requires a specified number of units, English, and a minimum number of subjects.

It does not require every student to study Chemistry.

Daniel can complete a valid HSC pattern without Chemistry.

Step 2: Check the university requirements.

Daniel should identify the actual degrees he might consider and determine whether Chemistry is:

• A formal prerequisite.
• Assumed knowledge.
• Recommended study.

These categories lead to different decisions.

If Chemistry is a formal prerequisite, studying another science subject will not automatically satisfy it.

If it is assumed knowledge, Daniel may be able to enter the degree without Chemistry but need additional preparation.

Step 3: Discuss school arrangements.

Daniel should ask whether the school can arrange an approved alternative way to study Chemistry.

He should also ask whether the subject might run at another time or whether another suitable arrangement is available.

Step 4: Compare the available pathways.

If Chemistry cannot be studied, Daniel should compare university courses and alternative preparation options before deciding on his remaining subjects.

The school’s inability to run a particular course is a practical limitation, not a statewide change to HSC requirements or university admission rules.

Question 5

Jordan is in Year 10 and choosing subjects for Year 11 in 2027.

He enjoys Visual Arts and product design. He also has a genuine interest in engineering but isn’t sure whether he wants to pursue it.

His school offers the following options:

• Mathematics Advanced can be studied in a separate timetable line.
• Physics and Visual Arts are in the same timetable line, so he must choose one.
• Mathematics Extension 1 is not available in his preferred timetable combination.

Jordan expects to achieve at least Band 4 in Mathematics Advanced. His Physics results are weaker, and he enjoys Visual Arts considerably more.

He investigates three universities and finds the following information:

University of Sydney

Its current published requirements include a mathematics prerequisite for Engineering. NSW HSC applicants need Band 4 in Mathematics Advanced or Band E3 in Mathematics Extension 1 or 2.

UNSW

Its general admission policy states that it does not have formal HSC subject prerequisites for its degrees.

However, its 2027 Engineering guide lists Mathematics Extension 1 and Physics as assumed knowledge. Students who haven’t studied these subjects are advised to undertake bridging courses or other preparation.

UTS

Its current policy states that it has no HSC subject prerequisites, although individual faculties may identify assumed knowledge and recommended studies.

Jordan is willing to complete additional preparation at university if necessary.

He is considering three possible directions:

• Engineering.
• Product and industrial design.
• A broader science or technology degree.

Which subject combination is the most defensible choice under these circumstances?

Explain what this combination preserves, what preparation it sacrifices, and what additional information Jordan should check before finalising his decision.

Solution 5

On the information given, Mathematics Advanced and Visual Arts are the more defensible choices for Jordan, provided he is confident of achieving the required Mathematics Advanced result and is prepared to address any missing university assumed knowledge.

The key is that the formal mathematics prerequisite and the Physics assumed knowledge are not equivalent requirements.

Step 1: Identify the most important formal admission condition.

The University of Sydney’s current Engineering requirements specify Band 4 in Mathematics Advanced or Band E3 in Mathematics Extension 1 or 2.

Jordan expects to achieve Band 4 in Mathematics Advanced.

Therefore, choosing Mathematics Advanced preserves the possibility of meeting this particular formal requirement.

Choosing Physics instead of Mathematics Advanced would not compensate for failing to meet the mathematics prerequisite.

Mathematics Advanced is therefore an important enabling choice for his shortlist.

Step 2: Examine the UNSW requirements separately.

UNSW’s 2027 Engineering guide lists Mathematics Extension 1 and Physics as assumed knowledge.

However, its general policy explains that assumed knowledge is not a formal admission prerequisite.

Jordan could still be considered for admission without those subjects under the current policy, but he would need to address the resulting knowledge gaps.

He should investigate bridging courses or other preparation in mathematics and Physics.

This is a real trade-off, not a reason to assume that the engineering pathway has disappeared.

Step 3: Consider the UTS pathway.

UTS does not have HSC subject prerequisites for its courses under its current domestic admissions policy.

However, Jordan should still check the individual degree pages for assumed knowledge and recommended studies.

Not having Physics does not automatically rule out every possible technology or science degree.

Step 4: Consider his personal interests.

Jordan genuinely enjoys Visual Arts and product design.

Physics is less appealing to him, and his current results suggest it may demand considerably more effort.

Since Physics is assumed knowledge rather than a formal admission prerequisite in the UNSW example, choosing Visual Arts is a reasonable decision if Jordan is comfortable undertaking additional preparation should he later pursue engineering.

Step 5: Identify the remaining risks.

This combination does not mean every engineering course will be equally accessible or that Jordan will be fully prepared for first-year engineering.

He needs to consider:

• Whether he can achieve Band 4 in Mathematics Advanced.
• Whether the specific engineering courses he might apply for have additional requirements.
• Whether he is prepared to complete Physics and Extension-level mathematics preparation if required.
• Whether his interest in engineering is strong enough to justify choosing Physics instead of Visual Arts.
• Whether the university requirements remain the same for his eventual intake.

The University of Sydney also publishes alternative ways of meeting its mathematics prerequisite, including an approved mathematics MOOC and examination. These are additional requirements to investigate, not a reason to ignore the HSC prerequisite.

The important distinction: Jordan should preserve the formal prerequisite that matters most to his plausible pathway, rather than assuming that every subject commonly associated with engineering is compulsory.

If engineering becomes his definite first choice, he might reasonably reconsider Physics and investigate whether his school can resolve the timetable clash.

If design remains his strongest interest and engineering is only one possibility, Mathematics Advanced and Visual Arts provide a sensible balance.

He should revisit the decision using the actual 2029 university admission requirements when they become available. The 2027 UNSW guide is an illustration of current policy, not a guarantee of future requirements.

10What to do next

If you still don’t know what you want to study after school, that’s fine.

You don’t need to solve your entire future before choosing your HSC subjects.

You need to make a series of smaller decisions:

1. Identify the subjects you enjoy and the areas in which you’ve demonstrated strength.
2. Shortlist two or three possible study directions.
3. Check whether any specific university courses have formal subject prerequisites.
4. Distinguish those prerequisites from assumed knowledge and recommended studies.
5. Confirm what your school can actually offer and timetable.
6. Choose a manageable combination that reflects your interests and preserves the pathways that matter to you.

Most importantly, don’t confuse keeping your options open with choosing the largest possible collection of difficult subjects.

A good subject combination is not necessarily the one with the most advanced courses. It is the one that gives you a realistic foundation for the next stage of your education.

And remember that your HSC subjects are not a permanent career decision. You can change your interests, explore different fields, and pursue alternative pathways after school.

For now, focus on making a decision you can explain: why you chose each subject, what it helps you prepare for, and whether you can see yourself putting consistent effort into it over the next two years.

That’s a much better starting point than choosing subjects based on what everyone else thinks you should do.
