How to Study Effectively: 10 Methods Backed by Research
UPDATED · 9 MIN READ
Most students study the way that feels productive: re-reading notes, highlighting and cramming the night before. Those habits feel good because the material starts to look familiar — but familiarity is not the same as being able to recall it in an exam.
Decades of learning research point to a small set of methods that work much better. None of them need more hours; they change what you do with the hours you already have. Here are ten, roughly in order of how much difference they make.
1. Test yourself instead of re-reading (active recall)
The single most effective change is to close the book and try to recall what you just learned. Pulling information out of memory strengthens it far more than reading it again — psychologists call this the testing effect, and it has been replicated in hundreds of studies.
In practice: after each section, write down or say everything you remember, answer practice questions, or use flashcards. It feels harder than re-reading. That difficulty is exactly what makes it work.

2. Spread your study sessions out (spaced repetition)
Studying a topic in several shorter sessions over days beats one long session, even when the total time is the same. Each time you come back just as you are starting to forget, the memory becomes more durable.
A simple schedule: review new material the next day, then after three days, then after a week, then before the exam. Flashcard reviews are an easy way to do this.
3. Work in focused blocks with breaks
Attention drops over long unbroken stretches. Short, timed blocks keep you honest and make starting easier, because you only commit to one block. The Pomodoro Technique — 25 minutes of focus, then a 5-minute break — is the most popular version.
4. Mix related topics (interleaving)
Practising one type of problem over and over feels efficient, but on a test you have to recognise which method a question needs. Mixing different problem types in one session — for example several kinds of equations — trains that choice and tends to improve exam performance, especially in math and science.
5. Explain it simply (the Feynman technique)
Try to explain a concept in plain words, as if to a younger student. Wherever you get stuck or reach for jargon, you have found a gap. Go back to the source for that part only, then explain it again.
6. Put your phone in another room
Every notification pulls you out of focus, and getting back in takes minutes. Even a silent phone on the desk is a temptation. Out of sight and out of reach is the most reliable fix.
7. Plan backwards from the exam
Write down the exam date, list every topic, and spread the topics over the days you have — leaving the last few days for mixed practice. A plan turns "I should study" into a specific task for today.
8. Sleep on it
Sleep is when the brain consolidates what you learned during the day. An all-nighter trades the memory you are trying to build for a few extra hours of tired reading. A good night before the exam is part of studying.
9. Study with other people — even silently
Working next to someone who is also focused makes it easier to start and harder to drift. That is why study with me videos and library sessions work. You can get the same effect online by studying together in a shared room.
10. Make it a habit, not a marathon
Consistency beats intensity. Forty-five focused minutes every day will outperform an eight-hour weekend cram. Track your study days and protect the streak.
A simple plan to start today
- Pick one topic you need to learn this week.
- Set a 25-minute timer and study it, phone in another room.
- Close your notes and write down everything you remember.
- Make flashcards for what you missed.
- Review those flashcards tomorrow, in three days and in a week.
Frequently asked questions
What is the most effective way to study?
Active recall — testing yourself instead of re-reading — combined with spaced repetition, reviewing material over several days, is the most consistently supported approach in learning research.
How long should I study each day?
Quality matters more than hours. For most students, two to four focused hours split into 25–50 minute blocks with breaks is more productive than long unbroken sessions.
Is re-reading notes a good way to study?
Re-reading makes material feel familiar but does little for recall. Use it briefly to refresh a topic, then switch to answering questions or explaining it from memory.
