How to Study Smarter, Not Harder: 10 Study Techniques Backed by Research

Instead of rereading your notes, close the notebook and try to explain what you just learned from memory.

Roediger and Karpicke (2006) found that students who practised retrieving material retained more of it on a delayed test than students who spent the same time rereading.

Try this:

• Read one section of your textbook.
• Close the book.
• Write down everything you remember.
• Compare your answers with your notes.
• Repeat until you can explain the topic without looking.

Instead of cramming the night before an exam, spread your studying across several days.

Cepeda and colleagues (2006) reviewed the spacing literature and found spaced practice generally produced better retention than the same study time massed together.

For example, instead of studying five hours on Sunday, study one hour a day from Monday to Friday.

Explaining a topic surfaces the parts you cannot yet put into words. Explain the concept to a friend, a family member, your study group, or out loud to yourself. If you cannot explain it simply, that is where to review.

Practical habit rather than a research finding: notifications interrupt the block you set aside.

• Put your phone on Do Not Disturb.
• Close unnecessary browser tabs.
• Study somewhere quiet.
• Keep only the materials you need open.

Many students find fixed work-and-break cycles easier to sustain. The Pomodoro pattern is one option:

• Study for 25-50 minutes.
• Take a 5-10 minute break.
• Repeat.

Block length is a preference. The uninterrupted part is what matters.

Testing yourself is the same mechanism as active recall, applied to whole topics. Use practice exams, flashcards, homework questions, essay prompts, or AI-generated quizzes — then check the answers against your course material.

Sleep is involved in consolidating what you studied, so a night lost to studying trades rehearsal for exhaustion. Most guidance for teenagers and adults lands in the 7-9 hour range.

Rotating between related problem types — known as interleaving — is one of the strategies reviewed by Dunlosky and colleagues (2013), which rated it as promising but with less evidence than practice testing and distributed practice.

Instead of asking AI for the answer, use it to explain difficult concepts, generate practice questions, create flashcards, summarize your notes, brainstorm essay ideas, or review writing you produced. AI can be confidently wrong, so verify anything factual, and check what your course allows: policies vary—check your course or instructor's rules.

Consistency is easier to maintain than intensity: 30-60 minutes most days also spreads your reviews out, which is the spacing effect doing the work for you.

Dunlosky, Rawson, Marsh, Nathan, and Willingham (2013) reviewed ten common learning techniques. They rated practice testing and distributed practice as high-utility, while rereading and highlighting were rated low-utility. That does not make rereading useless — it makes it a poor substitute for retrieval and spacing.

Individual results vary by subject, prior knowledge, and how the technique is applied. None of this predicts a particular grade.

What is the best study technique?

In the reviews above, practice testing combined with spaced review came out strongest for long-term retention.

How many hours should I study each day?

There is no research-backed universal number. Most students work with one to three focused hours a day depending on course load.

Can AI actually help students study?

It can explain concepts, generate quizzes, summarize notes, make flashcards, and give feedback on your own work. Whether it helps depends on using it to understand material rather than to replace doing it — and on your course policy.

There is no perfect way to study, but the research points in one direction: students retain more when they actively retrieve material than when they passively review it. Combining active recall, spaced practice, consistent sessions, and enough sleep is a reasonable plan for most courses.
