Study Skills Mistakes HSC Parents Can Look Out For

Sep 9, 2026

As a parent, it can be difficult to know whether your teenager is on track for the HSC.

You might see them sitting at their desk for hours, writing notes or telling you they have “nothing due this week”. But what does effective HSC preparation actually look like?

At HSC CoWorks, we’ve spent more than 30 years helping students navigate the HSC. One thing we know is that strong results rarely come down to simply working longer hours. There is well intentioned and ineffective study , or well intentioned and effective study and here are five study habits parents can look out for…

1. Waiting Until an Assessment or Exam Is Close Before Starting

One of the biggest HSC traps is allowing an upcoming deadline to determine when study begins. If your teen suddenly becomes extremely busy in the week before an assessment or spends the days before an exam cramming, they may be working hard but they’re working reactively.

The HSC is a marathon, not a series of last-minute sprints. At HSC CoWorks, we encourage students to think of themselves as being in training for the HSC. Just like an athlete doesn’t begin training the week before competition, students need to continually build their knowledge, skills and exam fitness throughout the year with proactive preparation.

What parents can look for: Is there consistent work happening each week, even when there isn’t an immediate deadline?

2. Not Knowing What They Need to Do This Week

Ask your teenager:

“What are your priorities this week?”

If the answer is “I don’t know”, “just homework” or “I’ll see what I have due”, there’s probably an opportunity to improve their planning. With five or six subjects competing for attention, HSC students need to continually decide where their time will have the greatest impact.

 

    That’s why planning and prioritisation are such an important part of the HSC CoWorks Program. Students are supported to identify upcoming assessments, gaps in their knowledge and the tasks that will move them forward.

    The goal isn’t for a coach or a parent to organise everything for them. It is to develop a student who can increasingly answer: What do I need to do next, and why?

    That independence is one of the most valuable skills students can take from their HSC year into life beyond school.

    3. Spending Hours Making Notes, But Not Testing Themselves

    This is one of the easiest traps for parents to miss because it looks like effective study.

    There are pages of notes. Highlighters everywhere. Maybe even a colour co-ordinated folder. But the exam won’t test you on how beautiful your notes look!

    The question is, can they actually retrieve that information without looking at their notes and can they apply it to an HSC style question?

    At HSC CoWorks, we encourage students to move beyond passive study and into active training: recalling content, answering exam-style questions, completing timed work and getting feedback on their responses throughout the year, not just in the lead up to an exam.

    A useful question for parents is:

    “What have you tested yourself on this week?”

    Another great way to support your child is to ask them to teach you what they are learning in say ‘Operations, Business Studies’. If it comes easy to them then they are showing they can easily retrieve the information and that they understand it.

     

    4. THEY Always Choosing the Work They Feel Comfortable Doing

    We all prefer doing things we’re good at.

    For an HSC student, that might mean spending another hour on Maths while avoiding an English essay. Revising familiar Biology content instead of tackling the topic they don’t understand. Or organising notes instead of attempting the practice paper they’re worried about.

    At HSC CoWorks, one of our key behaviours is to Push your Comfort Zone. The work students least want to do is often the work that offers the greatest opportunity for improvement.

    What parents can look for: Is your teenager regularly working on their weakest areas, or are they repeatedly choosing the tasks they already feel confident completing?

    5. Completing Practice Questions Without ANY Feedback

    Doing practice questions is important. But the real improvement often happens after the question has been completed. Students need to understand:

    • Where did I lose marks?
    • What was the marker looking for?
    • What could I have done differently?
    • How will I apply that next time?

    This feedback loop is a major part of HSC preparation.

    Through HSC CoWorks, students can complete exam-style questions, work with their coaches and access feedback from experienced HSC markers. The goal isn’t simply to complete more questions. It’s to continually improve the quality of the next response.

    That process of attempt, feedback, adjust, repeat is how students build exam confidence.

    Strong HSC preparation doesn’t need to mean studying every waking hour. It means consistently doing the right work:

    At HSC CoWorks, our role is to help students build these behaviours throughout their HSC journey, while providing the coaching, accountability, resources and expert support they need along the way.

    And importantly, the goal is to develop confident, independent students who know how to take ownership of their HSC and have strong lifelong skills to take with them into the next stage of life.

    Celebrating 30 years of HSC CoWorks! 💫 
In 1996, @fergusgardiner started working with a small group of HSC students in Bondi Junction. His ability to inspire a genuine passion for learning particularly in English quickly saw that small group grow through word of mouth. 
Fergus’ wife @carollgardiner alongside their son @jesseperformancecoach and his wife @sarahgards7 joined the business as it grew, helping to establish campuses in Mosman, Chatswood, Lindfield, Dee Why and Balgowlah. Jesse and Sarah now lead the organisation alongside an incredible team of more than 100 coaches, markers, teachers, an amazing Head Office and Web Development team, and also Emily and Nick who joined our team this year. There have been plenty of ups and downs, milestones, obstacles and lessons along the way, and HSC CoWorks wouldn’t be where it is today without the incredible people who have been part of it over the years.
And to every student who has walked through our doors and every parent who has trusted us to play a part in their child’s education, THANK YOU. Your support and trust over the past 30 years means more to us than we can say. We are so grateful to have worked with your child during the most important stage of their schooling career and thank you for championing our program as we strive to support young people develop the skills, habits and mindset that will support them long after their HSC.
And of course to our own family, especially our three children who put up with having both parents in the business and many weekends and evenings spent around the dinner table building new ideas, solving problems, packing study toolkits and everything in between!
We’re incredibly proud of what has been built over the past three decades, but even more excited about what comes next.
Thank you,
Jesse, Sarah, Fergus & Carol Gardiner
    The HSC matters. But what students build along the way matters even more.
The HSC year is your training ground for life.. where you can develop skills like how to plan ahead, take ownership, tackle challenges, respond to feedback and perform under pressure.
These aren’t just skills for getting through Year 12. They’re the skills, mindset and habits that you will take with you into university, work and whatever comes next.
At HSC CoWorks, our role is to provide the structure, support, coaching and accountability that helps students develop these capabilities, while working towards their HSC goals.

    The HSC isn’t meant to feel easy. But every time you choose to keep going, you’re building the confidence you’ll take into that exam room.
Do the hard work now. Thank yourself later. 💪
