Highlighters, rewriting notes, and rereading textbooks may feel safe, but research consistently shows that active, strategic study methods are far more effective.

We explore evidence-based study strategies that go beyond the basics, helping students prepare with confidence and clarity. Whether you’re a parent or student, this guide offers practical, research-informed approaches that can change the way you study for good.

Why common study habits don’t always work

Many students begin with what feels familiar: reading over notes, highlighting key phrases, and rewriting content. These are known as passive study techniques – they help students feel busy, but don’t require the brain to actively retrieve or apply knowledge.

The NSW Education Standards Authority (NESA) highlights that successful exam preparation depends on active engagement with content. That means retrieving information, testing understanding, and applying knowledge in varied contexts to deepen learning and build confidence in using that knowledge effectively.

Fortunately, there are more effective ways to revise – ones that are grounded in educational psychology and backed by Australian classroom research.

1. Spaced repetition: learning that sticks

Spaced repetition is the process of reviewing information at increasing intervals over time, rather than cramming it all into one study session. It works because our brains tend to forget new information quickly, but by revisiting it just as it’s about to be forgotten, we strengthen memory pathways.

How to implement it:

Start early and schedule multiple short sessions for each topic, spaced days or weeks apart. Use tools like digital flashcards (Anki, Quizlet), or manually rotate topics in a revision planner.

Why it’s effective:

A study by The University of Queensland found that spaced learning improves recall and academic outcomes, particularly in subjects requiring factual retention and detailed understanding. It’s especially useful in subjects like science, legal studies, and PDHPE.

2. Active recall: testing yourself builds memory

Active recall is exactly what it sounds like – trying to recall information from memory, without looking at your notes. It’s one of the most effective and underused study methods.

How to do it:

After reading a section of notes, close the book and write down everything you can remember. Use flashcards, quiz questions, or simply try explaining the topic aloud to yourself or someone else.

What makes it powerful:

According to Michael Owen, a current member of the Osmosis Health Leadership Initiative (OHLI) program, active recall outperforms most other revision strategies in terms of efficiency and retention. It strengthens memory and quickly highlights areas of weakness.

3. Practice with past papers: real experience, real growth

Doing past HSC papers under exam conditions helps students become familiar with question structures, marking expectations, and time management. It also builds the resilience needed to maintain focus under pressure.

Best practices:

• Time yourself strictly to mimic the real exam environment.
• Use marking guidelines to assess your responses.
• Don’t just complete the paper, review what you got wrong and revise accordingly, or better still have a teacher review and provide feedback.

Why it matters:

This approach builds exam stamina and reinforces content under realistic constraints. It’s one of the most valuable tools in any senior student’s study routine.

4. Interleaving: mix your subjects for deeper learning

Interleaving involves studying multiple topics or subjects within a single session, rather than focusing on one at a time (known as “blocking”). While it may feel disorganised at first, interleaving has been shown to enhance understanding and improve performance on problem-solving tasks.

How to apply it:

Instead of doing three hours of uninterrupted maths, study 45 minutes of maths, then 45 minutes of biology, then 45 minutes of English. Rotate again later in the week.

The science behind it:

By mixing up subjects, students must continually adapt and switch between types of thinking. This mirrors the unpredictable nature of exam questions and improves the brain’s ability to retrieve and apply knowledge flexibly.

5. Elaborative interrogation: the power of asking “why?”

Elaborative interrogation is a fancy term for asking questions while you study—especially “why” and “how” something works. This helps students move beyond rote learning and into deeper understanding.

Practical examples:

• In legal studies: “Why does this law exist?”
• In history: “How did this event influence later developments?”
• In science: “Why is this process necessary in the body?”

The impact:

Explaining ideas in your own words or linking them to real-world examples forces your brain to form meaningful connections. This makes the information easier to recall and more relevant during exams.

6. Brain dumping: clearing the clutter

“Blurting” or brain dumping is a fast, simple method of active recall. It involves writing down everything you know about a topic, cold, without notes, as quickly as possible.

Why it works:

It simulates the pressure of an exam while revealing how much you actually know. Once the dump is complete, compare it to your notes to identify what you missed. It’s ideal for visual learners and can be repeated multiple times with different topics.

7. Teaching someone else: the ultimate test

Teaching a concept forces you to understand it deeply. If you can explain something in simple terms, you likely understand it well. If you can’t, it’s a cue to revisit the material.

How to try it:

• Teach a sibling or friend
• Explain the concept aloud to a parent
• Record yourself on your phone and play it back
• Use a whiteboard or paper to draw diagrams as you teach

Bonus tip:

The Feynman Technique, named after physicist Richard Feynman, is based entirely on this principle: “If you can’t explain it simply, you don’t understand it well enough.”

8. Streamline your notes: from detailed to distilled

Creating notes is only half the process. The most effective note-takers revise their material by gradually reducing it—moving from full notes, to dot points, to cue cards, to single-page summaries or mind maps.

How to structure it:

• First: Create comprehensive topic summaries
• Next: Condense into key ideas and visuals
• Finally: Use these condensed versions for quick daily reviews

This layered method helps students build familiarity with content while making revision more efficient as the exam approaches.

How parents can support smarter studying

Parents often want to help but may not know where to start, particularly if their child is stressed. The key is not hovering or checking every answer, it’s encouraging consistency and supporting effective methods.

Here’s how parents can help:

• Ask your child to explain topics to you
• Help them plan spaced revision in a calendar
• Encourage regular use of past papers
• Remind them of evidence-based methods rather than more hours
• Ensure they have a quiet dedicated space to study.

By guiding rather than managing, parents empower their teens to take ownership of their learning.

At All Saints Grammar, we believe that preparing for exams is not just about knowledge, it’s about skill, strategy, and confidence. That’s why we support our senior students with structured revision programs, workshops, and subject-specific guidance rooted in proven learning techniques.

From Year 10 through to the HSC, our teaching staff help students develop the habits and strategies that lead to academic success. To learn more about our commitment to learning and excellence, download our prospectus.
