So, how do top students study? Top students study by using research-backed methods that actually work, including active recall, spaced repetition, interleaving, focused study sessions, and adequate sleep. These evidence-based techniques improve memory, learning, and exam performance much more effectively than highlighting or rereading.
The student who sits in the library for eight hours straight, highlighter in hand, textbook open, feels like they’re doing the right thing. The research says otherwise. Highlighting and rereading sit at the bottom of every evidence-based ranking of study techniques, which is why top students rely on more effective learning methods instead.
- Highlighting and rereading are classified as low utility in peer-reviewed research, specifically in Psychological Science in the Public Interest.
- If there’s one study hack worth trusting, it’s active recall. Testing yourself, no notes in sight, beats rereading every single time.
- Ever heard of spaced repetition? Reviewing stuff at growing gaps—a day, three days, a week, a month—does more for retention than people realise. Two focused hours this way can match six hours of last-minute cramming.
- Most students think they’ve clocked way more study hours than they really have. The gap’s not small either, somewhere between 30 and 50%.
- And weirdly, switching between subjects mid-session, rather than sticking to one, tends to help things stick for longer.
- Four focused hours outperform eight distracted ones.
- Sleep is where memory consolidation actually happens, not at the desk.
They feel productive, but they produce weak results. Top students figured this out, most of them the hard way, and what they do instead is genuinely different from what the average student does.
How Do Top Students Study? A Few Methods
Top students aren’t necessarily the ones who spend the most time studying—they’re the ones who use their time wisely. By following a few effective study techniques, you can remember concepts better, stay confident, and get more out of every study session.
Scientific Utility and Retention Impact of Study Techniques
| Study Technique | Scientific Utility Rating | Avg. Long-Term Retention | Time Efficiency Factor | Primary Cognitive Process |
|---|---|---|---|---|
| Active Recall (Self-Testing) | High Utility | 75% – 80% | 3x higher than passive methods | Information Retrieval |
| Spaced Repetition | High Utility | 70% – 75% | 3x vs last-minute cramming | Memory Consolidation |
| Interleaving (Mixing Topics) | Moderate Utility | 60% – 68% | 1.5x vs blocked study | Context Discrimination |
| Rereading Notes/Textbooks | Low Utility | 15% – 20% | Baseline standard | Passive Recognition |
| Highlighting & Underlining | Low Utility | 10% – 12% | Baseline standard | Visual Familiarity |
| Cramming (Massed Practice) | Low Utility | Less than 10% (after 7 days) | 0.3x long-term return | Short-Term Buffer Storage |

The Fluency Trap
Here’s what happens when you reread your notes. The material starts to feel familiar. That familiarity registers in your brain as understanding, and you close the notebook feeling like you’ve got it. You probably don’t. What you’ve trained is recognition, not recall. Recognition means you can identify the right answer when it’s in front of you. Recall means you can produce it without anything in front of you. Exams test recall. Rereading doesn’t train it.
This is called the fluency illusion, and it’s the reason students are consistently blindsided by how poorly an exam goes after what felt like adequate preparation. The method felt right. The method wasn’t working.
Active Recall
Close the book. Write down everything you can remember from the last lecture or chapter. Don’t look at your notes while you do it. Then check what you missed. That process, uncomfortable and effortful and nothing like reading, is active recall, and it’s the most evidence-backed study technique available.
Research by Roediger and Karpicke found that students who practised active recall after studying retained around 50% more than students who reread the same material. A 2025 study published in ScienceDirect confirmed the same finding specifically among medicine and pharmacy students, groups who need information to stick for months, not just until Friday.
Flashcards are the simplest form. Practice questions are another. The Feynman technique, where you try to explain something as clearly as possible to an imaginary ten-year-old, is a more demanding version that works particularly well for conceptual subjects. The point in all cases is the same: make your brain retrieve the information rather than just look at it again.

Spaced Repetition
This goes back to Hermann Ebbinghaus in the 1800s; he’s the one who first mapped the forgetting curve. His finding: without reviewing new info at the right moment, we forget close to 70% of it within 24 hours. Spaced repetition exists because of that exact problem. Review right before forgetting kicks in, and every successful recall lets you push the next review a little further out.
Here’s the surprising bit—two hours spent this way match what six hours of cramming gets you in terms of retention. Not a motivational quote, just what the data keeps showing. Anki, Quizlet, tools like that automate the scheduling for you, tracking how sure you were when recalling something and timing the next review accordingly. Medical students figured this out ages ago since they simply have too much to remember long-term for cramming to work.
Start earlier. That’s the only catch. Spaced repetition doesn’t work the night before an exam.
How Time Actually Gets Wasted?
Students overestimate how long they’ve studied by 30 to 50%. Sitting at a desk with notes open isn’t the same as studying. The first twenty minutes of most sessions are spent settling in. The last hour tends to drift. What’s in the middle is often interrupted by phones, music, ambient noise, or the mental effort of suppressing all three.
Phone in another room. Not face-down on the desk, because research shows that even the visible presence of a smartphone reduces available cognitive capacity regardless of whether you’re using it. Actually, another room.
Here’s a direct fix for the attention problem: 25 minutes of dead-focused work, then five minutes off. Do that four times, then reward yourself with a longer break. Sounds a little forced when you first try it, like you’re gaming your own brain. Except it works; one clean 25-minute stretch with zero distractions beats two hours of half-paying-attention every time.
Why Mixing Things Up Works Better Than You’d Expect
Most students study one subject at a time, all the biology, then all the history, then all the maths. It feels organised. The research calls this blocking and consistently shows it produces worse long-term retention than interleaving, which means mixing different subjects or problem types within the same session.
The reason is straightforward—when you block study, your brain runs the same retrieval process on repeat and never has to work out which approach applies. When you interleave, your brain has to identify the right strategy from scratch each time, which is exactly what an exam requires when you don’t know what’s coming next.
It’s harder. That’s the point. The difficulty is the learning happening.
The Recovery Part Nobody Takes Seriously
Top students treat sleep and exercise as part of studying, not as breaks from it. Memory consolidation happens during sleep, specifically during the deep sleep phases. Reviewing material lightly before bed improves next-day retention. Staying up all night before an exam trades the consolidation that would have happened during sleep for a few extra hours of material that won’t stick anywhere useful.
Exercise increases blood flow to the brain and has measurable positive effects on memory formation and cognitive performance. A twenty-minute walk between study sessions isn’t time lost. It’s time that improves what comes after it.
The Honest Version
None of this is easier than rereading your notes. Active recall is uncomfortable because you’ll get things wrong. Spaced repetition requires you to start weeks before the exam, not the night before. Focused Pomodoro blocks with no phone in the room require more discipline than sitting somewhere with your notes open while half-watching something.
But the techniques that feel demanding in the moment are demanding because they’re making your brain do actual work. The ones that feel comfortable are comfortable because they aren’t.

FAQs
Q1. What Do Top Students Do Differently When They Study?
They ditch rereading in favour of retrieval. Think active recall, spaced repetition, distraction-free focus blocks. Harder than highlighting? Definitely. That’s the entire point.
Q2. Is Highlighting A Good Way To Study?
Not really, no. All it does is train you to recognise stuff you’ve seen before, and recognition feels like learning even when it isn’t. But exams don’t ask you to recognise anything; they ask you to produce answers cold. Highlighting won’t get you there.
Q3. What Is Active Recall And How Does It Work?
You shut your notes and try recalling the material before peeking again. Mess it up? Doesn’t matter; that’s actually where the learning happens. Flashcards, practice questions, talking through a topic out loud without any notes—it all falls under this.
Q4. What Is Spaced Repetition?
Rather than dumping all your review into the night before, spread it out: a day later, then three days, then a week, then a month. Each time recall succeeds, you stretch the gap before the next review. Two hours spaced out this way retain more than six hours crammed in. That’s just what the data says, no motivational spin needed.
Q5. Does It Matter How Long You Study?
Not as much as people think. Four hours of properly focused active recall will beat eight hours of half-distracted note-staring, phone face-down or not. Being at a desk isn’t the same thing as studying.
Q6. Why Does Interleaving Work Better Than One Subject At A Time?
Your brain stops running on autopilot. Grinding through all your maths then all your history means repeating the same mental process the whole time. Mix them and your brain has to actually work out which method applies, just like on exam day.
Q7. How Does Sleep Affect Studying?
A lot more than students tend to think. Consolidation, the process that actually locks memories in, happens while you sleep, not while you’re hunched over notes. A light review before bed helps things stick. An all-nighter, on the other hand, just trades that consolidation for extra cramming hours that won’t hold up by morning anyway.
