What Is the Best Way to Study? Methods That Actually Work

Most students study by rereading notes and highlighting textbooks. Both feel productive and both perform poorly in controlled comparisons. The methods that work best often feel harder, which is exactly why they are avoided.

Here is what the evidence supports, in order of how much difference it makes.

Active recall

Active recall means testing yourself instead of reviewing material. Close the book and try to produce the answer from memory.

The reason it works is that retrieving information strengthens the memory far more than seeing it again. Each successful recall makes the next one easier. Rereading creates a feeling of familiarity that is easily mistaken for knowing, which is why students who reread feel confident and then perform worse than expected.

Ways to apply it:

• Flashcards, physical or digital
• Closing your notes and writing down everything you remember, then checking what you missed
• Practice questions and past papers
• Explaining a topic out loud as if teaching it

The uncomfortable feeling of struggling to remember is the method working, not failing.

Spaced repetition

Spacing means reviewing at increasing intervals instead of all at once.

Studying something for four hours in one evening produces weaker retention than four one hour sessions spread across two weeks, even though the total time is identical. Memory consolidates in the gaps between sessions.

A workable schedule for new material: review after one day, then three days, then a week, then two weeks, then a month. Software such as Anki handles the scheduling automatically, but a paper system works too.

Combining spacing with active recall is the single most effective pairing available, and it costs nothing.

Interleaving

Interleaving means mixing different topics or problem types in one session rather than doing all of one kind before moving on.

Blocked practice (twenty problems of the same type) produces better performance during the session and worse performance later. Interleaved practice feels messier and performs better on the exam, because exams do not tell you which method to apply.

This matters most in mathematics, physics and anything where choosing the right approach is part of the difficulty.

Elaboration

Elaboration means asking why and how rather than only what. Connect new material to things you already understand, explain mechanisms rather than memorising conclusions, and ask yourself why a fact is true.

Material understood as a connected structure is far easier to retain than a list.

What does not work as well as people think

• Rereading. The most common technique and among the least effective per hour spent.
• Highlighting. Passive, and it tends to mark what looks important rather than what you do not yet know.
• Copying out notes. Feels like work, and is largely transcription rather than thinking.
• Cramming. Produces short term recall that fades quickly. It can pass an exam tomorrow and leaves little behind.
• Learning styles. The idea that people are visual or auditory learners and should be taught accordingly has repeatedly failed to hold up in testing.
• Background music with lyrics. Competes for the same processing as reading for most people.

Building a schedule

1. Work in focused blocks. Something like 25 to 50 minutes of work followed by a short break. The exact numbers matter less than the rhythm.
2. Decide the task, not the duration. “Three past paper questions” ends. “Study chemistry for two hours” drifts.
3. Put the hardest subject first, while attention is freshest.
4. Review before new material. Ten minutes of recall from last session before starting anything new.
5. Protect sleep. Memory consolidation happens during sleep, so a late night of cramming works against the thing you just studied. Our guide on how to get good sleep covers the practical side.

Removing distraction

Phone in another room, not face down on the desk. Research on attention has repeatedly found that a visible phone reduces available attention even when it is not used.

Switching between tasks has a cost each time, so what feels like studying with occasional messages is closer to repeatedly restarting.

Frequently asked questions

How many hours a day should I study?

Two to four hours of genuinely focused work is more than most people manage, and beats eight distracted hours. Quality of attention matters more than time logged.

Is it better to study at night or in the morning?

Whichever you can do consistently and alertly. Consistency matters more than the hour, and sleep should not be sacrificed for either.

Do study groups help?

They help when the group tests each other and explains concepts aloud. They waste time when they become a shared reading session.

How do I stop forgetting what I studied?

Spacing. Forgetting is normal, and the fix is scheduled review rather than studying harder the first time.

Should I take notes by hand or on a laptop?

Handwriting is slower, which forces summarising rather than transcribing, and that usually aids understanding. Laptops are better where volume or searchability matters.

How far ahead should I start revising?

Several weeks for a major exam, so spacing has room to work. Starting late forces cramming, which is the weakest option available.
