Many students spend hours rereading notes and highlighting textbooks, yet still forget everything on exam day. The problem usually isn’t effort. It’s the method. Decades of cognitive psychology research show that some study techniques backed by science work far better than others.
A well-known review by Dunlosky and colleagues (2013) compared common learning strategies and found that popular habits like highlighting and rereading offered low benefit, while practice testing and spaced practice delivered much stronger results. Here are the 10 best study techniques that research supports, and how to use each one.
1. Active Recall (Practice Testing)
Active recall means pulling information out of your memory instead of passively reviewing it. Close your book and write down everything you remember, answer practice questions, or use flashcards.
Why it works: Retrieving a memory strengthens it, a finding known as the testing effect. Struggling to remember is what makes the memory stick.
How to use it: After each study session, test yourself without looking at your notes, then check what you missed.
2. Spaced Repetition
Instead of cramming, spread your study sessions over days and weeks. This technique is also called distributed practice.
Why it works: Hermann Ebbinghaus’s forgetting curve showed that we lose new information quickly unless we review it. Reviewing just as you begin to forget resets the curve and makes the memory last longer.
How to use it: Review material after 1 day, 3 days, 1 week, and 2 weeks. Apps like Anki automate this schedule.
3. Interleaving
Interleaving means mixing different topics or problem types in one session instead of studying one topic in a long block.
Why it works: Switching between topics forces your brain to identify which method fits which problem, which improves long-term retention and problem-solving. It feels harder, but studies on math and sports skills show better results.
How to use it: Instead of doing 30 algebra problems in a row, mix algebra, geometry, and statistics problems in one sitting.
4. Elaborative Interrogation
This technique means asking yourself “why?” and “how?” while you study, instead of just memorizing facts.
Why it works: Explaining why a fact is true links it to what you already know, building stronger and more meaningful memory connections.
How to use it: For every concept, ask: Why does this happen? How does it connect to what I learned before?
5. Self-Explanation and the Feynman Technique
The Feynman Technique means explaining a concept in simple language, as if teaching a beginner.
Why it works: Research on self-explanation shows that putting ideas in your own words exposes gaps in understanding you didn’t know you had.
How to use it:
- Pick a topic.
- Explain it aloud or in writing without notes.
- Note where you got stuck.
- Go back, relearn those parts, and simplify further.
6. Dual Coding
Dual coding combines words with visuals such as diagrams, charts, timelines, and sketches.
Why it works: According to Allan Paivio’s dual coding theory, information stored in both verbal and visual form gives your brain two routes to retrieve it.
How to use it: Turn your notes into mind maps, flowcharts, or labeled drawings. You don’t need artistic skill, just clear visuals.
7. Mnemonics and the Method of Loci
Mnemonics are memory aids such as acronyms, rhymes, and vivid mental images. The method of loci (memory palace) links items to familiar places, such as the rooms of your home.
Why it works: Vivid, structured associations are easier to recall than abstract facts, which is why memory champions rely on these methods.
How to use it: Picture walking through your house, placing one key idea in each room. To recall the list, walk through again mentally.
8. The Pomodoro Technique and Focused Study Blocks
The Pomodoro Technique uses 25 minutes of focused study followed by a 5-minute break, with a longer break after four rounds.
Why it works: Short, focused intervals reduce mental fatigue and make it easier to start. Research on attention shows that distractions, especially phones, reduce learning quality.
How to use it: Set a timer, silence notifications, and work on one task only. Adjust the interval (for example, 40/10) to suit you.
9. Quality Sleep
Sleep isn’t a break from learning. It’s part of it.
Why it works: During sleep, especially deep sleep, your brain consolidates new memories and moves them into long-term storage. Studies consistently link sleep deprivation to poorer attention and memory.
How to use it: Avoid all-nighters. Review key material before bed and aim for 7 to 9 hours of sleep, particularly before an exam.
10. Regular Physical Exercise
Exercise helps your brain as much as your body.
Why it works: Research suggests aerobic activity improves blood flow, mood, and attention, and may support memory and learning.
How to use it: Take a 20 to 30 minute walk, jog, or workout on study days. Even a short walk during a break can help you refocus.
Techniques That Don’t Work as Well
Highlighting, underlining, and rereading are among the most popular habits, but they were rated low-utility in major reviews. They create a feeling of familiarity without building real understanding. If you use them, pair them with active recall.
How to Combine These Study Techniques
You don’t need all ten at once. Here’s a simple weekly plan:
- Learn: Use dual coding and elaborative interrogation when first studying a topic.
- Practice: Use active recall and interleaving during practice sessions.
- Review: Use spaced repetition to revisit material over time.
- Support: Use Pomodoro blocks, sleep, and exercise to keep your brain performing at its best.
Frequently Asked Questions
What is the most effective study technique?
Research most strongly supports active recall and spaced repetition. Used together, they outperform passive methods like rereading.
Do these study techniques work for competitive exams?
Yes. Because these methods are based on how memory works, they apply to school tests, university exams, and competitive exams alike. Active recall and spaced repetition are especially useful for large syllabi.
What are the best study methods for ADHD?
Short Pomodoro-style blocks, active recall, visual notes, and regular movement breaks often help with focus. Individual needs differ, so a doctor or learning specialist can offer personalized guidance.
How long should I study at a time?
Most people focus best in 25 to 50 minute sessions with short breaks. Adjust the length to your attention span and the difficulty of the subject.
Final Thoughts
The best study techniques aren’t about studying longer. They’re about studying smarter. Start with active recall and spaced repetition, add interleaving and visual notes, and protect your sleep. Try one or two techniques this week, see how they feel, and build from there. Your future exam self will thank you.
