Most students study by re-reading and highlighting. Research says these are among the least effective methods. Here are 5 that work.
1. Active Recall
Test yourself instead of re-reading. Close your textbook, write everything you remember, check what you missed.
2. Spaced Repetition
Review at increasing intervals: Day 1, Day 3, Day 7, Day 14, then monthly.
3. The Feynman Technique
Write the topic
e.g. Newtons Second Law
Explain simply
No jargon. If you cannot explain it simply, you do not understand it.
Find the gaps
Where you got stuck = what to restudy.
Simplify again
Repeat until crystal clear.
4. Practice Testing
Past papers force your brain to retrieve under pressure.
5. Interleaving
Mix topics in one session: 1hr calculus, 1hr trig, 1hr algebra.

Stop Studying Harder — Start Studying Smarter
You’ve been told to “just study more.” But more hours doesn’t mean better results. Research in cognitive science shows that how you study matters far more than how long you study. The difference between a student who gets 80% and one who gets 50% often isn’t intelligence — it’s method.
Here are five study techniques backed by actual research, explained in a way that makes them easy to use right now.
1. Active Recall
What it is: Testing yourself on material instead of re-reading it.
Why it works: Every time you force your brain to retrieve information, the memory gets stronger. Re-reading your notes feels productive, but it creates a false sense of knowing. You recognise the material, but you can’t reproduce it under exam conditions.
How to do it:
- Close your textbook after reading a section
- Write down everything you remember on a blank page
- Open the textbook and check what you missed
- Focus your next study session on the gaps
You can also make flashcards with questions on one side and answers on the other. The key is: don’t flip the card until you’ve genuinely tried to answer.
2. Spaced Repetition
What it is: Reviewing material at increasing intervals over time.
Why it works: Your brain forgets things in a predictable pattern (the “forgetting curve”). If you review just as you’re about to forget, the memory consolidates and lasts longer each time.
How to do it:
- Study a topic today
- Review it tomorrow
- Review again in 3 days
- Then in 1 week
- Then in 2 weeks
This is why last-minute cramming doesn’t work. You might pass the test, but you’ll forget everything within days. Spaced repetition builds long-term knowledge — which is what you need for final exams.
3. The Feynman Technique
What it is: Explaining a concept in simple language, as if you’re teaching a child.
Why it works: If you can’t explain something simply, you don’t really understand it. This technique forces you to find the gaps in your understanding and fill them.
How to do it:
- Choose a concept (e.g., “photosynthesis” or “Newton’s Third Law”)
- Write an explanation using only simple words — no jargon
- When you get stuck, go back to your notes and fill the gap
- Simplify your explanation until a 10-year-old could understand it
This works especially well for subjects like Life Sciences, History, and Business Studies where you need to explain processes and concepts in exams.
4. Practice Testing (Past Papers)
What it is: Doing full exam-style questions under timed conditions.
Why it works: Past papers show you exactly how questions are asked, how marks are allocated, and what the examiners expect. They also train you to work under time pressure — something no amount of note-reading can prepare you for.
How to do it:
- Get past papers from the Department of Education or from OLA’s resource library
- Set a timer for the full exam duration
- Do the paper without looking at your notes
- Mark it using the official memo
- Write down every question you got wrong and WHY you got it wrong
The marking step is where the real learning happens. Don’t just check your answers — understand the memo’s reasoning.
5. Interleaving
What it is: Mixing different topics or subjects in a single study session instead of focusing on one thing for hours.
Why it works: Interleaving forces your brain to constantly switch between different types of problems, which improves your ability to identify which method to use — a critical skill in exams where questions aren’t labelled by topic.
How to do it:
- Instead of doing 20 algebra problems in a row, do 5 algebra, then 5 geometry, then 5 trigonometry, then back to algebra
- Mix subjects too — 45 minutes of Maths, then 45 minutes of English, then back to Maths
It feels harder than doing one thing at a time — and that’s exactly why it works. The difficulty is what makes the learning stick.
Which Method Should You Use?
All of them. These techniques aren’t competing — they’re complementary. A strong study session might look like this:
- Read a section of your textbook (10 min)
- Close it and do active recall — write what you remember (10 min)
- Explain the concept in simple terms — Feynman technique (5 min)
- Do past paper questions on that topic (20 min)
- Switch to a different subject — interleaving (next block)
- Review yesterday’s material — spaced repetition (5 min)
The students who get top marks aren’t necessarily smarter. They’ve just found methods that work and they stick with them consistently.
