Whether you’re a student trying to ace your exams, a professional preparing for certifications, or a lifelong learner mastering a new skill—how you study matters more than how long you study.
While many people stick to old habits like rereading notes or highlighting textbooks, research has shown that these methods are often inefficient. The good news? Cognitive scientists and psychologists have uncovered powerful, evidence-based techniques that help you retain information better, focus deeper, and learn faster.
Here are 6 study hacks backed by science that will transform the way you learn:
1. Use Spaced Repetition to Strengthen Memory
Why it works:
The Spacing Effect, first studied by psychologist Hermann Ebbinghaus, shows that information is better retained when reviewed at increasing intervals over time rather than crammed in one sitting.
How to do it:
Use tools like Anki or Quizlet that use spaced repetition algorithms to automatically schedule your reviews. Start by reviewing new material shortly after you learn it, then again in a day, then a few days later, and so on.
Pro tip:
Combine spaced repetition with active recall (testing yourself) for maximum retention.
2. Practice Retrieval Instead of Rereading
Why it works:
A landmark study by Jeffrey Karpicke (Purdue University) revealed that students who tested themselves recalled 50% more information than those who simply reread their notes. This technique is called retrieval practice.
How to do it:
- After reading a section, close the book and write down or recite everything you remember.
- Use flashcards, mock tests, or explain the concept to someone else.
- Ask yourself questions like: “What did I just learn?” or “How does this relate to what I already know?”
Pro tip:
Don’t worry if you struggle to recall at first—that struggle strengthens memory.
3. Interleave Subjects Instead of Blocking
Why it works:
Blocking (studying one subject for a long time) feels comfortable but is less effective. Interleaving—mixing different topics or types of problems in one study session—forces your brain to stay alert and makes the learning deeper.
Scientific evidence:
A study published in Applied Cognitive Psychology found that students who interleaved math problems performed 43% better on tests compared to those who used blocked practice.
How to do it:
Mix subjects or topics: For example, instead of studying only biology for 2 hours, rotate between biology, chemistry, and physics in 30-minute blocks.
Pro tip:
Combine this with retrieval practice for a powerful double boost.
4. Apply the Pomodoro Technique for Laser Focus
Why it works:
The brain can only maintain deep concentration for a limited time. The Pomodoro Technique breaks study time into focused sprints followed by short breaks, which helps prevent mental fatigue and improve productivity.
How to do it:
- Set a timer for 25 minutes of focused study.
- Take a 5-minute break.
- After 4 Pomodoros, take a 15-30 minute longer break.
Use apps like Focus Keeper or Pomofocus to automate the process.
Pro tip:
During breaks, avoid social media. Instead, stretch, breathe, or walk to reset your mind.
5. Study in Different Locations to Enhance Recall
Why it works:
This might sound counterintuitive, but research from Psychological Science suggests that studying in multiple environments can improve memory recall. It prevents your brain from tying the information to one specific context.
How to do it:
Alternate between your room, a library, a café, or different areas of your house. If changing locations isn’t possible, simply changing your posture, lighting, or even the music can help.
Pro tip:
Try to review the same material in different locations to build versatile memory connections.
6. Sleep After Studying to Lock in Learning
Why it works:
Sleep isn’t just rest—it’s a time when your brain consolidates what you’ve learned. A study from Harvard Medical School showed that students who slept after studying retained more information than those who stayed awake.
How to do it:
- Study before bed or take a power nap after learning something new.
- Ensure you get 7–9 hours of quality sleep each night.
- Avoid all-nighters, as sleep deprivation can severely impair memory and focus.
Pro tip:
Even a 20-minute nap after an intense study session can significantly boost retention.
Study Smarter, Not Longer
