Best Study Techniques for College Students, Ranked by Evidence

Most students study the way they always have: reread the notes, highlight the textbook, make a neat summary and hope it sticks. These habits feel productive because the material looks familiar afterward. Familiarity is not the same as knowing it, and the gap shows up in the exam.

A large body of research in cognitive psychology points to a short list of methods that reliably improve learning. This guide ranks them, shows how to use each, and explains which popular habits to drop.

What the research says

In 2013, a team of psychologists led by John Dunlosky published a widely cited review of ten common learning techniques. They rated practice testing and distributed practice as high in usefulness, while rereading, highlighting, summarizing and keyword mnemonics were rated low or moderate for typical students. Later work has refined the details, but the core message has held up: the methods that feel hardest while you do them usually produce the strongest learning.

That idea has a name, desirable difficulty. Effortful retrieval, spacing and mixing topics all make studying feel slower and messier, and all improve what you remember weeks later.

The ranking, from most to least useful

Rankings simplify things, and the best plan combines several of these. But if you change only one habit, change what you do with your notes: stop rereading them and start testing yourself on them.

1. Practice testing

Close the book and try to recall what you just studied. Write it out, say it aloud, answer flashcards or work a practice problem. Each retrieval attempt strengthens the memory, and failed attempts show you exactly what to study next.

How to use it:

• turn headings and key terms in your notes into questions;
• use flashcards, past papers or end-of-chapter questions;
• do a blank-page recall: write everything you remember about a topic, then check against your notes;
• test yourself before you feel ready, since struggling is part of the benefit.

Our guide to active recall vs rereading goes deeper on why this works and how to do it.

2. Spaced practice

Studying a topic several times over days or weeks beats the same total time in one block. Cramming can get you through tomorrow's quiz, but the memory fades quickly. Spacing forces your brain to retrieve the material again after a little forgetting, which strengthens it.

How to use it:

• review each topic a day, a week and a few weeks after first learning it;
• schedule short review sessions in your calendar rather than one long session before the exam;
• use a flashcard app that schedules reviews for you.

See spaced repetition explained for a simple schedule.

3. Interleaving

Mix different topics or problem types in one session instead of finishing one completely before moving on. It feels less smooth, but it trains you to choose the right method for each problem, which is what exams demand.

4. Elaboration and self-explanation

Ask yourself why a fact is true, how it connects to what you already know, and what would change if one condition changed. Explaining a step in your own words, aloud or on paper, exposes gaps in understanding that rereading hides.

5. Summarizing from memory

A summary written while looking at the text mostly copies it. A summary written from memory, then checked against the source, is a form of practice testing. The difference is whether you retrieve or transcribe.

Techniques that waste your time

• Rereading. It builds familiarity quickly, which makes you feel prepared, but it does little for later recall.
• Highlighting. Marking text rarely helps unless you go back and test yourself on what you marked.
• Copying notes out neatly. It is a calm activity, and calm is not the same as learning.
• Passive video watching. Watching a lecture again is rereading with a screen.
• Studying in long, unfocused marathons. Tired study gives poor returns.

None of these are forbidden. They are fine for a first pass at new material. The problem is stopping there.

Putting it together: a weekly pattern

A simple routine that uses the best methods:

1. After each lecture, write three questions from the material.
2. Within a day, answer them from memory and check your notes.
3. Each week, spend 30 minutes testing yourself on that week and the week before.
4. Before an exam, do mixed practice questions across all topics, under time pressure.
5. After each test, write down what you missed and when you will review it again.

This takes no more total time than rereading, and much of it fits into short gaps. A flashcard tool can handle the scheduling.

Planning a single study session

Knowing the techniques is one thing. Fitting them into an hour is another. A reliable structure for a 60-minute session:

1. Minutes 0 to 5: warm up by recalling, from memory, what you covered last time. Write it down before checking.
2. Minutes 5 to 30: study new material actively. Read a section, close the book, and write questions and answers about it.
3. Minutes 30 to 45: do mixed practice, with problems or questions from several earlier topics.
4. Minutes 45 to 55: check your answers, and mark what you missed.
5. Minutes 55 to 60: write down what you will review next time and when.

Notice how much of the hour is retrieval and feedback, and how little is reading.

What studying needs around it

Techniques only work if your brain is in a state to use them. A few basics matter more than any method:

• Sleep. Memory is consolidated during sleep, so trading sleep for study hours usually loses more than it gains.
• Exercise. Regular physical activity supports concentration and mood.
• Breaks. Short breaks between focused sessions keep quality up across a long day.
• Distraction control. A phone within reach lowers the quality of study even when you do not touch it.

Adjusting for different subjects

• Math and sciences: work problems without looking at the solution first, then compare. Mix problem types.
• Languages: speak and write, not just read. Review vocabulary on a schedule.
• History and humanities: explain causes and arguments in your own words, then check them. Practice essay plans.
• Law and medicine: use cases and clinical scenarios as retrieval prompts, plus spaced flashcards for facts.

How to tell what is working for you

Research tells you what works on average. You are not average, so check the results in your own courses. After each quiz or exam, look at the questions you missed and ask which kind of studying would have caught them. If the missed items were facts, add retrieval and spacing. If they were problems, add mixed practice. If they were essay arguments, practice outlining from memory.

Keep a short log for a few weeks: the course, what you did, how long it took, and how the next test went. Patterns appear quickly, and they tend to point the same way as the research. The log also gives you something concrete to show an advisor or tutor if you need help.

Common mistakes

1. Confusing familiarity with knowledge. If you recognize it, you may still not recall it.
2. Studying only the easy topics because they feel good.
3. Waiting until you feel ready to test yourself.
4. Skipping review after the first week.
5. Never checking. Self-testing is only useful if you read the answers afterward.

A final test

Pick one topic from this week. Without notes, write down everything you can about it in five minutes, then check. What you missed is your study plan. Repeating that exercise, spaced across days, is the most dependable technique there is.
