If there's one thing I noticed among state rankers and students who scored 99+ ATARs (including during my own 99.30 HSC journey), it's this: they don't study 14 hours a day. They just know what actually moves the needle, and what is a complete waste of time.
Most students spend hours passively highlighting textbooks, copying down summary notes, and wondering why their marks stall in the 70s. Top students do things very differently.
Here is the exact step-by-step playbook for how to study for HSC Maths, Science (Physics & Chemistry), and Software Engineering so you can get the best possible marks.
📐 The HSC Maths Playbook
For Mathematics, the golden rule is simple: Stay ahead.
Do not wait for your teacher to introduce a topic. If you are looking at a concept for the first time on the whiteboard in class, you are already playing catch-up. Class time should be used to test your understanding, clarify edge cases, and work on hard questions — not to see the theory for the very first time.
Phase 1: The Help Hierarchy (How to Learn Any Method)
When you hit a wall and don't know how to solve a question, do not immediately run to your teacher saying "I don't get it." Use this specific pipeline to figure out the method:
- Textbook: Look closely at the worked examples first. Most of the time, the step you're stuck on is demonstrated in an earlier sample problem.
- AI (ChatGPT / Gemini): Type the question in and ask:
"Explain the steps to solve this, like I am a high school student." This gives you an instant, step-by-step walkthrough of the algebra. - Friend: Ask a mate who understands it. Teaching you actually helps them solidify their own knowledge, and you get an explanation in plain student language.
- Teacher: Only go to your teacher when you have exhausted the first three. This ensures your questions are targeted (e.g., "I get step 1 and 2, but why did we factorise in step 3?"). Teachers will give you much better help when you ask specific questions.
Phase 2: The Practice Vault
Let's be real: just doing textbook questions will only get you to Band 3 or Band 4. Standard textbook exercises are designed to teach basic mechanics, but they won't prepare you for real HSC and trial questions. Your best friends are past papers:
- SmarterMaths: Incredible for targeted, topic-by-topic HSC-style practice.
- THSC Online & Ace HSC: These are absolute goldmines. They contain trial papers from state-ranking selective schools like James Ruse, Baulkham Hills, and North Sydney Boys. If you want a 99 ATAR, you need to do the papers the 99 ATAR students are doing.
🧬 The HSC Science Playbook (Physics & Chemistry)
Science is heavily conceptual. Just like Maths, you need to stay ahead. Read the syllabus dot points before class. When you are in class, your goal should be to answer questions and connect dots, not just blindly copy notes.
Phase 1: Mastering the Concept
If you don't understand the why behind a concept, you will struggle with the 7–9 mark extended response questions. Use this pipeline:
- Atomi: Start here for a high-level, visual understanding of the concept. It makes complex physics and chemistry ideas digestible fast.
- Textbook: Read the chapter to lock down the nitty-gritty details and specific NESA terminology.
- Science Ready (YouTube): Go here for in-depth, HSC-specific explanations. It bridges the gap between basic understanding and Band 6 knowledge.
Phase 2: The Practice Vault
- Start with Atomi quizzes and textbook exercises to test your baseline memory.
- Move rapidly to THSC Online. Applying your knowledge to actual past HSC and trial papers is the only way to learn how NESA wants you to structure your scientific answers.
💻 The Software Engineering Ghost Town
If you are taking Software Engineering, you already know the struggle. Unlike Physics or Advanced Maths, it is a complete ghost town for public resources online. There are almost no quality trial papers or comprehensive question banks available.
Because I know exactly how frustrating this is, we put together a comprehensive 80-page Software Engineering document covering every syllabus point, worked algorithms, pseudocode breakdowns, and sample responses.
🎁 Want Access to Our 80-Page Software Engineering Guide?
We share this resource directly with our students. When you book a free 1-on-1 trial session with us, we will give you access to the guide and walk you through how to tackle your subjects step-by-step!
The Bottom Line
The resources are out there. But resources are just tools — they only work if you know exactly what to focus on and what to ignore.
You can spend hundreds of hours figuring out the HSC trends through brutal trial and error like I did, or you can get targeted, expert help to buy back your time and social life.
