Should I Choose HSC Physics? A Practical Year 10 Guide

Imagine two Year 10 students choosing subjects. One likes space, electricity, and figuring out why things move, but gets nervous whenever algebra appears. The other is strong at maths but finds questions about forces, waves, and experiments painfully boring. Which one should choose Physics?

There isn’t enough information yet.

HSC Physics sits at the intersection of interest, mathematical reasoning, scientific explanation, practical investigation, and workload. Being “good at maths” helps, but it doesn’t automatically make Physics a good choice. Loving space documentaries doesn’t automatically make it a good choice either.

For a Year 10 student choosing subjects in 2026, there’s another detail worth knowing: you’ll be among the first students taught under the new Physics 11-12 Syllabus from 2027, with the first HSC examination for that syllabus in 2028. (NSW Curriculum)

So the useful question isn’t simply, “Is Physics hard?”

It’s:

Does the kind of difficulty in Physics suit me, and am I willing to build the skills it requires?

01What will you actually study?

Physics is mostly about building models of things you can observe, then using those models to make predictions.

Suppose you throw a basketball forwards.

You could ask:

• Why does it curve towards the ground?
• What determines how far it travels?
• Does a harder throw keep it in the air longer?
• What forces act on it after it leaves your hand?
• Can we predict where it will land?

That is much closer to Physics than memorising a page of facts about basketballs.

Under the new syllabus, Year 11 has three main focus areas:

Year 12 then develops this into Advanced mechanics, Electromagnetism, Nature of light, and Matter, energy and the cosmos. Both Year 11 and Year 12 are 120-hour, 2-unit courses, and each includes 10 hours of depth studies. (NSW Curriculum)

That range matters.

You might love astronomy but still spend a considerable amount of time analysing mechanics and electromagnetic systems. Conversely, you don’t need to arrive in Year 11 already obsessed with every branch of physics.

Quick prediction

Which sounds more like HSC Physics?

A. Memorising 40 facts about how electricity works.

B. Looking at a circuit, deciding what should happen, calculating a quantity, then explaining whether the result makes physical sense.

Answer: B.

There is knowledge to learn, but NESA explicitly includes problem-solving, analysing data, making predictions, scientific investigations, and communicating scientific arguments as part of the course. (NSW Curriculum)

02How mathematical is HSC Physics?

This is usually the biggest concern, so it’s worth being precise.

Physics uses maths constantly, but the difficult part often isn’t the arithmetic.

Consider:

\[
v = u + at
\]

where:

• \(v\) is final velocity in metres per second,
• \(u\) is initial velocity in metres per second,
• \(a\) is acceleration in metres per second squared, and
• \(t\) is time in seconds.

Typing numbers into that equation is easy.

The more important questions are:

• Is this the correct model for the situation?
• Which direction should be positive?
• Which quantities do I actually know?
• Do I need to rearrange the equation?
• Does my answer make physical sense?

A formula isn’t a vending machine where you insert three numbers, press =, and physics falls out.

It’s better to think of an equation as a compressed scientific sentence. It tells you how physical quantities are related.

Try this before deciding that you’re “bad at Physics”

A cyclist increases speed from \(4.0\text{ m s}^{-1}\) to \(10.0\text{ m s}^{-1}\) in \(3.0\text{ s}\). What is the average acceleration?

Acceleration measures how quickly velocity changes:

\[
a = \frac{v-u}{t}
\]

Step 1: Identify the quantities

\[
u=4.0\text{ m s}^{-1}, \quad v=10.0\text{ m s}^{-1}, \quad t=3.0\text{ s}
\]

Step 2: Substitute

\[
a=\frac{10.0-4.0}{3.0}
\]

Step 3: Calculate

\[
a=2.0\text{ m s}^{-2}
\]

The cyclist’s velocity increases by \(2.0\text{ m s}^{-1}\) each second on average.

If you didn’t know the formula beforehand, that’s completely fine. The more useful question is: once the relationship was explained, did the reasoning feel manageable?

That is a much better indicator than whether you already know Year 11 Physics.

03How good at maths do I need to be?

NESA lists no formal prerequisite or corequisite for Year 11 Physics. (NSW Curriculum)

That doesn’t mean maths is irrelevant.

You should expect to work with skills such as:

• rearranging equations
• ratios and proportional relationships
• interpreting graphs
• gradients
• scientific notation
• basic geometry
• trigonometry
• vectors and direction
• substituting values while keeping track of units

You do not need to begin Year 11 having mastered all of these.

You do need to be willing to practise them.

A useful distinction

Suppose your current maths problem is:

“I’m sometimes slow with algebra, but once someone explains it, I can practise until I understand it.”

Physics is still very realistic.

That’s different from:

“I strongly dislike algebra, graphs, calculations, and anything involving equations, and I don’t want to spend time improving them.”

That combination makes Physics much harder to recommend.

The issue isn’t some magical minimum Year 10 maths mark. It’s whether you have enough foundation, and enough willingness, to strengthen the mathematics Physics repeatedly uses.

If you’re also deciding what senior maths course to take, don’t assume that choosing Physics automatically means you must take the highest maths level available. Choose your maths course on its own merits. Our guide to Maths Extension 1 vs Extension 2: What Actually Changes? explains that decision separately.

04Physics isn’t only calculation

Here’s a common trap.

A student sees equations everywhere and decides:

“Great. I like maths, so I’ll just calculate everything.”

That works until Physics asks you to explain something.

Imagine a ball travelling horizontally off the edge of a table. Ignore air resistance.

Predict first: once the ball leaves the table, is there still a horizontal force pushing it forwards?

It feels as though there should be. After all, it keeps travelling forwards.

But there isn’t.

Its horizontal velocity continues because an object doesn’t need a net force merely to keep moving at constant velocity. Gravity provides a downward force, which changes the ball’s vertical motion.

So Physics requires you to separate:

what you see

from

the model that explains why it happens.

That is why students who are excellent at calculations can still lose marks if their conceptual understanding is weak.

05What do Physics assessments actually feel like?

Don’t choose a subject from the textbook alone. You also have to live with its assessments.

For the new syllabus, NESA gives school-based assessment a 60% emphasis on Working scientifically skills and 40% on knowledge and understanding in both Year 11 and Year 12. Schools still determine the exact tasks and their individual weightings. (NSW Curriculum)

Working scientifically includes things such as:

• making and evaluating predictions
• planning investigations
• collecting data
• processing graphs and measurements
• evaluating evidence
• solving scientific problems
• communicating an argument clearly

Scientific investigations may involve laboratory work, simulations, modelling, data analysis, and secondary-source research. (NSW Curriculum)

So Physics isn’t just “study equations, sit test”.

A depth study, for example, could require you to investigate a question, obtain or analyse data, recognise limitations, and justify a conclusion.

Does that assessment style suit you?

If you like questions where there is something to work out, Physics may suit you.

If you like analysing graphs and figuring out why experimental results don’t perfectly match theory, even better.

If you strongly prefer subjects where success mainly comes from memorising material and reproducing it accurately, Physics may feel less comfortable.

That isn’t a judgement about which style is better. It’s about which sort of work you’re happier doing for two years.

06The HSC exam is not just dozens of tiny calculations

For the first examination under the new syllabus in 2028, NESA specifies a 100-mark written paper with 3 hours of working time plus 10 minutes reading time.

It contains:

• 20 marks of objective-response questions, and
• 80 marks of other questions, including at least two items worth 7 to 9 marks.

Working scientifically skills can be assessed throughout the paper. (NSW Curriculum)

That means you’ll need more than quick calculator skills.

Longer questions can require several moves:

1. interpret the scenario,
2. choose the relevant physics,
3. calculate,
4. use evidence or data,
5. explain what the answer means, and
6. communicate it clearly.

If you tend to lose marks because you know the idea but can’t organise a response, that’s a skill you’ll need to work on.

It isn’t a reason by itself to avoid Physics.

07How heavy is the workload?

Physics is cumulative.

That’s probably the most important workload point.

If you don’t properly understand velocity and acceleration, later mechanics becomes harder. If basic electric concepts are shaky, later electromagnetism becomes harder.

It’s a little like building IKEA furniture while quietly skipping every third screw. It may look fine for several pages of the instruction booklet. Eventually the whole thing starts leaning.

This means Physics usually rewards small amounts of regular practice much more than a desperate weekend before an assessment.

A typical week may involve some combination of:

• learning a new physical model
• practising calculations
• reviewing earlier concepts
• interpreting graphs
• completing practical work
• writing explanations
• analysing experimental data

How heavy that feels depends heavily on your school, teacher, assessment calendar, and your other subjects.

A student taking several mathematically demanding courses may find considerable overlap in skills, but also a lot of problem-solving homework. A student with several major projects or practical subjects may have a completely different workload problem.

So don’t ask, “Is Physics a heavy subject?”

Ask:

What will Physics look like alongside my other five or six subjects?

08Do I need to be naturally good at Physics?

No.

But you should distinguish between not knowing Physics yet and disliking the way Physics makes you think.

You’re in Year 10. You’re not supposed to already understand Year 12 electromagnetism.

Try this instead.

Mini diagnostic: forces

A shopping trolley is pushed with a force of \(30\text{ N}\) to the right. Friction acts with a force of \(18\text{ N}\) to the left.

Predict the net force before calculating it.

The trolley should have a force towards the right, because the push is stronger than friction.

Step 1: Choose a positive direction

Take right as positive.

Step 2: Add the forces with their directions

\[
F_{\text{net}}=30+(-18)
\]

Step 3: Calculate

\[
F_{\text{net}}=12\text{ N}
\]

So the net force is \(12\text{ N}\) to the right.

Now ask yourself something more useful than “Was that easy?”

Did you like translating a physical situation into a model?

If you got the answer wrong but wanted to know why, that’s a promising sign.

If your reaction was, “Please never make me think about a shopping trolley again”, that’s also useful information.

09What kind of student tends to enjoy Physics?

You don’t need every characteristic below.

Physics is worth serious consideration if several sound like you:

• You often want to know why something happens rather than only what happened.
• You enjoy problems where you have to combine several pieces of information.
• You’re comfortable with maths, or you’re prepared to improve it.
• You don’t mind diagrams, graphs, and measurements.
• You like finding patterns in data.
• You can tolerate getting a problem wrong, checking your assumptions, and trying again.
• You’re interested in motion, energy, electricity, waves, light, technology, space, or how physical systems behave.
• You prefer understanding a smaller number of powerful ideas over memorising large amounts of disconnected information.

None of these means you’ll automatically score highly.

They simply describe the sort of thinking the course repeatedly asks you to do.

10Who should think more carefully before choosing it?

Physics deserves a second look if you’re mainly choosing it because:

• someone told you “smart students do Physics”
• you’ve heard rumours about scaling
• your friends are taking it
• you think it will contain almost no writing
• you think being good at maths makes understanding the physics automatic
• you’re hoping to avoid regular study
• you strongly dislike both mathematical problem-solving and scientific explanations

UAC’s own advice to Year 10 students is to consider your goals, abilities, and interests rather than choosing HSC subjects simply because of scaling. (Universities Admissions Centre)

Scaling is not a substitute for being able to learn and perform in the subject.

11Physics compared with other science choices

There isn’t a sensible universal ranking of Physics, Chemistry, Biology, or other science courses. They demand different combinations of skills.

This is a rough decision guide, not a statement that one course is inherently harder or better.

Don’t decide from this table alone.

Look at the actual syllabus and, more importantly, a real assessment task from your school. Schools can make different decisions about task formats and assessment schedules.

12What about university?

This is where subject selection advice often becomes much too confident.

Taking HSC Physics does not guarantee entry into a particular university degree.

Not taking it does not automatically close every science or engineering pathway either.

The exact situation depends on the university, degree, and year you apply.

For example, UAC’s 2026 Year 10 guidance lists Physics as assumed knowledge for some engineering courses, while institutions may also offer bridging options where assumed knowledge hasn’t been completed. (Universities Admissions Centre)

“Assumed knowledge” and “prerequisite” are also not the same thing.

A prerequisite is normally something you must satisfy to be eligible for the course.

Assumed knowledge means the university expects you to arrive with that background, even where it isn’t an admission requirement.

If you’re considering engineering, physics, some technology fields, or another degree with substantial physical science, studying Physics at school may therefore be useful preparation.

But don’t rely on a friend’s older sibling saying, “You need Physics for engineering.”

Check the current requirements for the actual degrees you’re considering.

You’re choosing subjects in 2026 for university entry several years later. Requirements can change.

13What if I’m interested in engineering?

Physics and engineering overlap strongly in the kinds of problems they investigate: motion, forces, energy, electrical systems, modelling, and quantitative reasoning.

That still doesn’t mean:

engineering = compulsory HSC Physics everywhere.

University requirements differ.

A better decision process is:

1. Find two or three engineering degrees you might realistically consider.
2. Check their prerequisites.
3. Check their assumed knowledge.
4. Check their recommended studies.
5. Check whether bridging options exist.
6. Then decide how much value HSC Physics would add for you.

That is much safer than choosing two years of school based on a vague idea of what university “probably wants”.

14A short self-check

Don’t assign yourself points. There is no scientifically meaningful “Physics suitability score”.

Instead, answer these honestly.

1. When something behaves unexpectedly, do I usually want to know why?

If yes, Physics has a lot to offer. Much of the course involves explaining behaviour using models.

If no, that’s not automatically a problem. But if you generally dislike analysing causes and would rather learn facts directly, look closely at a sample Physics lesson before choosing it.

2. Can I rearrange a simple equation, or am I willing to learn?

For example, from

\[
F=ma
\]

could you make \(a\) the subject?

Divide both sides by \(m\):

\[
a=\frac{F}{m}
\]

If this is currently difficult but understandable once shown, that’s workable.

If algebra has large gaps, use the remainder of Year 10 to fix them.

3. What happens when I get stuck on a maths or science problem?

If you usually try another approach, check your working, or ask for help, that suits Physics well.

If one failed attempt normally means abandoning the question, you’ll need to change that habit. Physics problems often require a second attempt.

4. Am I choosing Physics for the subject itself?

Having a future career in mind is useful.

Choosing it only because it sounds prestigious is not.

Two years is a long time to spend with a subject you don’t actually like.

5. What else am I taking?

Write down your proposed Year 11 subjects.

Then mark which ones are likely to require:

• frequent problem practice,
• major projects,
• large amounts of reading,
• practical work, or
• substantial homework.

The issue is not whether Physics is manageable in isolation. It’s whether the whole combination is manageable for you.

6. Have I seen real HSC-style Physics yet?

If not, your opinion of Physics may currently be based almost entirely on Year 10 Science.

That’s weak evidence.

Try several actual questions before making the decision.

15One important issue for the 2027 Year 11 cohort

If you’re in Year 10 in 2026, the syllabus timing matters.

The new Physics 11-12 Syllabus begins with Year 11 in Term 1, 2027, and its first HSC examination will be in 2028. (NSW Curriculum)

That means your cohort won’t have years of previous HSC papers written specifically for the exact new syllabus.

NESA has published sample examination materials, but older Physics papers were written for the previous syllabus. (NSW Curriculum)

Older questions can still be useful where content and skills overlap. They just shouldn’t automatically be treated as perfect replicas of what your own HSC will look like.

This is worth asking your prospective Physics teacher about:

How is the school adapting its Year 11 program and assessments to the new syllabus?

A specific answer is much more useful than simply asking whether Physics is “hard”.

16So, should you choose HSC Physics?

There are three fairly common situations.

Physics is probably worth strong consideration

You have at least some interest in how physical systems work, you’re reasonably comfortable with mathematical reasoning or willing to improve it, and you don’t mind explaining ideas as well as calculating answers.

You don’t need to be the top maths student in your year.

Physics could work, but fix something first

You like the subject but have weaknesses in algebra, graphs, scientific writing, or study habits.

Those are trainable problems.

Use the end of Year 10 to strengthen them rather than assuming they permanently disqualify you.

You should seriously compare other subjects

You have little interest in the content, strongly dislike quantitative problem-solving, and are mainly considering Physics because of scaling, prestige, friends, or pressure from someone else.

In that case, another course may use your time better.

17What to do before submitting your subject choices

Do these four things rather than making the decision from reputation.

1. Read the current Physics syllabus overview.
For students entering Year 11 in 2027, make sure you’re looking at the Physics 11-12 Syllabus (2025), not only material describing the outgoing 2017 syllabus. (NSW Curriculum)

2. Ask your school’s Physics teacher for a real sample.
Ask for one typical Year 11 worksheet and, if possible, one sample assessment task. Ten minutes looking at actual work tells you more than someone saying, “Physics is pretty hard.”

3. Test your maths foundations.
Check equation rearrangement, graphs, scientific notation, basic trigonometry, and units. Anything weak now can become a Year 10 revision target.

4. Check future courses individually.
If Physics is part of your university planning, use the current university or UAC information for the degrees you may want. Look specifically for the words prerequisite, assumed knowledge, and recommended studies.

Your final choice doesn’t need to be based on whether Physics is objectively “easy” or “hard”. It should be based on something more useful: whether its particular mix of maths, modelling, experiments, problem-solving, and explanation is work you’re prepared to get better at.
