Can you differentiate y = (3x² + 2) to the power of 5 for me please
Good choice of question before trials. This one uses the chain rule. Before I show you the full working, can you tell me what the outer function and the inner function are?
outer is something to the power 5, inner is 3x² + 2
Exactly right. Here is the full step by step working:
📋 Step by step working
1
Identify functions
u = 3x²+2, y = u&sup5;
2
Differentiate u
du/dx = 6x
3
Differentiate y
dy/du = 5u⁴
4
Chain rule
dy/dx = dy/du × du/dx
5
Final answer
30x(3x²+2)⁴
Now try y = (2x³ − 1)⁴ yourself. What is du/dx for this one?

Quality HSC support at a price that makes sense.

Private HSC tutors typically charge $90 to $150 per hour. SubjectMate gives your child NESA aligned support every night for a flat monthly fee.

How it works for HSC students
Built for how HSC students actually study.

Year 11 and 12 students need exam technique, structured working and explanations that translate into marks.

Step by step working that mirrors NESA marking.

Every multi-step problem is broken into numbered steps in the format NESA markers reward. Your child sees how a high scoring response is structured, not just the answer.

The tutor always asks your child to attempt each step before showing it, keeping the thinking active.

How do I calculate the pH of a 0.05 mol/L solution of HCl?
HCl is a strong acid so it dissociates completely. Before I show you the steps, can you tell me what that means for the concentration of H³O&sup+ ions?
The H3O+ concentration would also be 0.05?
Exactly right. Here is the full working:
📋 Step by step working
1
Strong acid: full dissociation
[H³O&sup+] = 0.05 mol/L
2
Apply pH formula
pH = −log[H³O&sup+]
3
Substitute
pH = −log(0.05)
4
Final answer
pH = 1.30
Now try a weak acid. If acetic acid has Ka = 1.8 x 10 to the power of negative 5 at 0.1 mol/L, what is the first step?

Writing feedback matched to HSC marking criteria.

Paste a practice response and get feedback structured around actual HSC marking criteria: specific strengths, one focused improvement, and a model paragraph.

Every comment references something your child actually wrote. Specific and actionable, not generic.

What is working
Argument: Your thesis is sustained across every paragraph and returns in the conclusion. This is the control that markers are looking for in an extended response.
Evidence: Quotes are integrated into your own sentences rather than dropped in. The analysis that follows each one is specific to the text, not generic.
What to improve
Conclusion: Your final paragraph restates the argument rather than extending it. A stronger conclusion opens a broader implication or leaves a question for the reader. It should add to the essay, not summarise it.
What a strong conclusion looks like
Winton's treatment of memory and place ultimately asks us not just to understand the Australian experience, but to consider what it means to be shaped by landscape in a country still learning to reconcile its histories.

Exam technique built into every session.

SubjectMate teaches your child how to approach HSC questions, not just answer them. The tutor identifies what each question is asking, works through it systematically, and checks working against what a marker expects.

For extended responses, the tutor explains how marks are allocated and where students most commonly drop them.

This question is worth 15 marks. How do I know how much to write?
A 15-mark extended response in Legal Studies is looking for sustained legal reasoning across the whole response, so roughly three to four paragraphs each making a distinct point. The first thing to do is identify the directive verb in the question. What does this one ask you to do?
It says "assess the effectiveness"
Good. "Assess" means you need to make a judgement and support it with evidence. The marker wants to see you weigh up both sides and arrive at a supported conclusion, not just describe. Every paragraph should include a legal case, legislation or treaty, and your analysis of what it shows about effectiveness. Shall we work through the first paragraph together?

An interactive geometry whiteboard built into every session.

SubjectMate opens a live Desmos whiteboard directly in the tutor panel. Drag vertices, explore angle relationships and watch measurements update in real time.

The tutor always asks for a prediction before the construction loads. The whiteboard is a tool for discovery, not a shortcut to the answer.

Science simulations for Chemistry, Physics and Biology.

SubjectMate loads a PhET interactive simulation directly in the tutor panel. Adjust variables, run experiments and observe results in real time.

The tutor always asks for a prediction before anything changes, building the scientific thinking HSC markers look for.

What HSC families are saying.

Real results from Year 11 and 12 families who have used SubjectMate through the HSC.

★★★★★
Year 12 Chemistry: eight marks up in one assessment

"She kept losing marks on extended responses and we couldn't figure out why. Turned out her working wasn't laid out the way markers want it. SubjectMate fixed that pretty fast, showed her exactly how to structure each step. Next assessment she picked up eight marks. Honestly did not expect it to make that much of a difference that quickly."

Year 12 Maths: confident going into trials

"Look, Year 12 costs enough as it is. We couldn't justify a private tutor at those hourly rates on top of everything else, so we tried SubjectMate. Best decision we made all year. Jack used it most nights leading into trials and he went in calm for the first time ever. That alone was worth it for us."

From the student

"I kept losing marks in maths without knowing why. SubjectMate showed me that I was skipping steps that markers actually need to see. Once I started writing out every step properly my marks went up and I didn't even feel like I was doing anything differently."
