Quick Answer: Ranked by research evidence: (1) Practice testing — highest effectiveness, consistently outperforms all other methods; (2) Distributed practice — spreading study sessions across multiple days beats cramming; (3) Elaborative interrogation — asking "why is this true?" as you study; (4) Self-explanation — teaching concepts to yourself out loud. Re-reading and highlighting — the most common methods — are rated Low effectiveness. The single best change most college students can make: replace half your re-reading time with self-testing.
Choosing the best study methods for college is one of the most important decisions you can make as a student, yet most people never evaluate whether their study strategies actually work. Research in cognitive psychology has tested the most common study techniques in rigorous experiments, and the results are clear: some methods are dramatically more effective than others, and the techniques most students rely on are among the least effective.
This guide ranks the most popular study methods based on published research, explains why each technique works or does not work, and shows you how to build a study system using only the highest-rated strategies.
The Ranking Criteria
Our rankings are based on peer-reviewed research from cognitive science and educational psychology. We evaluated each technique on three dimensions: how much it improves performance on later tests, how well the benefits transfer to different types of material, and how practical it is for real college students to implement consistently.
Each method receives a rating of High, Moderate, or Low effectiveness.
Tier 1: Highly Effective Methods
These are the study methods that consistently produce the best results in research. If you only change one thing about your study habits, adopt one of these.
1. Practice Testing (Rating: High)
Practice testing means quizzing yourself on material rather than simply reviewing it. This includes using flashcards, completing practice exams, answering end-of-chapter questions from memory, and creating your own test questions.
What the research says. Dozens of studies confirm that students who test themselves retain significantly more than those who re-study. A landmark meta-analysis found that practice testing produced the largest and most consistent learning gains of any technique studied.
How to implement it. After each lecture or reading session, close your materials and write down everything you can remember. Create flashcards for key terms, concepts, and relationships. Complete all available practice problems and past exams. Form study groups where you quiz each other. To learn more about the science behind this, see our guide on what is active recall.
2. Distributed Practice (Rating: High)
Distributed practice means spreading your study over multiple sessions instead of cramming everything into one or two marathon sessions before an exam.
What the research says. The spacing effect is one of the most robust findings in all of psychology. Students who distribute their study over time consistently outperform those who mass their study, even when total study time is identical.
How to implement it. Plan your study schedule starting from the first week of the semester, not the week before the exam. Study each subject for 30-60 minutes per day rather than several hours in one sitting. Review material from previous weeks regularly, not just the current week's content. Use a spaced repetition system to automate your review schedule.
3. Interleaved Practice (Rating: High)
Interleaving means mixing different topics, problem types, or subjects within a single study session rather than studying one topic exhaustively before moving to the next.
What the research says. Interleaving consistently outperforms blocked practice (studying one topic at a time) in experiments across many domains including math, science, and vocabulary learning. The effect is large and reliable.
How to implement it. In a single study session, alternate between three or four topics rather than focusing on one. For math and science courses, mix problem types within your practice sets. When reviewing flashcards, shuffle decks from different subjects together.
Tier 2: Moderately Effective Methods
These techniques provide meaningful benefits and work well as supplements to the Tier 1 methods.
4. Elaborative Interrogation (Rating: Moderate to High)
This involves asking "why" and "how" questions about everything you study and then generating answers.
What the research says. Elaborative interrogation significantly improves learning compared to simple reading, particularly for factual material. The benefits are strongest when students already have some background knowledge in the subject.
How to implement it. For every fact or concept in your notes, ask "Why is this true?" and "How does this connect to what I already know?" Write your answers down. Do not just think about it; the act of generating a written explanation is what strengthens the memory.
5. Self-Explanation (Rating: Moderate to High)
Self-explanation involves pausing during learning to explain the material to yourself, particularly focusing on how new information relates to what you already know and why specific steps in a procedure work.
What the research says. Self-explanation improves both comprehension and retention across many types of material. Students who self-explain while working through examples learn more efficiently than those who simply study the examples.
How to implement it. When working through textbook examples, explain each step to yourself before moving on. When reading, pause after each paragraph or section and articulate the main point in your own words. The key to effective self-explanation is being specific and connecting new material to prior knowledge.
6. Concrete Examples (Rating: Moderate to High)
Generating specific, concrete examples of abstract concepts significantly improves understanding and recall.
What the research says. Concrete examples help students build mental models that make abstract concepts more memorable and easier to apply in new situations.
How to implement it. For every abstract concept, create at least two real-world examples. Prioritize examples from your own experience when possible. Compare and contrast multiple examples to understand what is essential to the concept versus what is incidental. For more strategies, see our guide on active reading strategies.
7. The Feynman Technique (Rating: Moderate to High)
Explaining a concept in the simplest possible terms, as if teaching it to someone with no background knowledge, reveals and fills gaps in your understanding.
How to implement it. Choose a concept from your notes, then explain it in writing using only simple language, no jargon. Where you get stuck, go back to your source material to fill the gap, then try your explanation again.
Tier 3: Low Effectiveness Methods (What to Stop Doing)
These are the study methods most college students rely on most heavily. Unfortunately, research consistently shows they produce poor results relative to the time invested.
8. Re-Reading (Rating: Low)
Re-reading notes or textbook chapters is the most common study strategy among college students and also one of the least effective.
What the research says. Multiple studies confirm that re-reading produces minimal improvements in retention compared to a single reading. The problem is that re-reading creates a feeling of familiarity that students mistake for actual learning. That warmth is the mere exposure effect: repetition increases how much you like material without increasing how much of it you can recall.
What to do instead. Replace re-reading with active recall. Instead of reading your notes again, close them and try to write down the key points from memory. The effort of retrieval is what produces lasting learning.
9. Highlighting and Underlining (Rating: Low)
Highlighting and underlining are ubiquitous study behaviors but they are largely passive activities that do very little for retention on their own.
What the research says. Research shows that highlighting does not improve performance on tests beyond simply reading the material. The physical act of highlighting creates an illusion of engagement without the cognitive effort needed for learning.
When highlighting can work. Highlighting is not entirely useless if it is paired with active strategies. If you highlight selectively (no more than 10-15% of text) and then use those highlights for active recall practice or spaced review, the highlighting serves as useful input for effective techniques.
10. Summarizing (Rating: Low to Moderate)
Writing summaries of what you have read is more effective than re-reading but far less effective than the Tier 1 techniques.
What the research says. Summarizing requires some generative processing, which is why it is slightly better than re-reading. However, the benefits are inconsistent across studies and depend heavily on the quality of the summaries produced.
What to do instead. Replace summarizing with practice testing or the Feynman Technique. Both require you to generate information from memory, which is more effective than condensing information you are looking at.
Time Cost vs. Effectiveness: Which Methods Are Worth Your Hours
The tier rankings above answer "does this work," but not "is this worth my time this week." A technique can be effective and still be a bad trade if it takes three times as long to set up as a higher-rated alternative. The clearest source for weighing both is Dunlosky, Rawson, Marsh, Nathan, and Willingham's 2013 paper "Improving Students' Learning With Effective Learning Techniques," published in Psychological Science in the Public Interest — the most-cited head-to-head evaluation of common study techniques in the field. The authors graded ten techniques on "utility," a combined measure of effect size, how well it generalizes across subjects and student ages, and how practical it is outside the lab.
| Method | Dunlosky et al. utility rating | Setup time cost | Ongoing time per session | Best fit |
|---|---|---|---|---|
| Practice testing | High | Low — needs only questions or flashcards | Low, a few minutes | Any material with a clear right answer |
| Distributed practice | High | Very low — a calendar is enough | None — same total hours, spread differently | Every course, every semester |
| Interleaved practice | Moderate | Low | Low | Math and science problem sets |
| Elaborative interrogation | Moderate | Low | Moderate — needs some background knowledge | Factual, conceptual material |
| Self-explanation | Moderate | Low | Moderate | Worked examples and procedures |
| Summarizing | Low | Moderate — requires real synthesis, not copying | Moderate | Weak substitute for the methods above |
| Highlighting/underlining | Low | Very low | None on its own | Marking passages for later retrieval, not a standalone method |
| Re-reading | Low | None | High — each pass costs as much as the first | Rarely worth it alone |
The pattern in Dunlosky's data is not subtle: the two highest-rated techniques, practice testing and distributed practice, are also the cheapest to set up. Neither requires special materials or extensive preparation — just a habit of closing your notes to quiz yourself and a calendar that spreads sessions across days instead of hours. Re-reading sits at the opposite corner: real time cost, almost no return once you've read the material once.
This is why the study system below leads with practice testing and distributed practice rather than treating all eight-plus techniques in this guide as equally worth adopting. When you are deciding where to spend a limited study budget, weigh the time-cost column as heavily as the effectiveness column. For more on why closed-book retrieval outperforms every passive alternative, see our retrieval practice guide and how to remember what you study for a course-by-course version of this workflow.
Building Your Study System: A Practical Framework
Now that you know which methods work, here is how to combine them into a cohesive study system.
During Lectures
Take notes using the Cornell method. Leave a column on the left for questions and keywords that you fill in after the lecture. This sets you up for active recall practice later.
Same-Day Review (15-20 Minutes)
Within 24 hours of a lecture, close your notes and practice active recall by writing down everything you remember. Then open your notes and check what you missed. Use elaborative interrogation to ask "why" and "how" about the points you missed. Understanding how to remember what you read is foundational to this process.
Weekly Review Sessions (1-2 Hours Per Course)
Interleave your review across topics from the past several weeks. Use practice testing: work through problems, answer questions from memory, and quiz yourself with flashcards. Distribute these sessions across multiple days rather than doing one long session.
Exam Preparation (Starting 2+ Weeks Before)
Shift to intensive practice testing under exam-like conditions. Use past exams if available. Focus your review on material you struggle to recall rather than material you already know well. Continue distributing your practice over multiple days.
Ongoing Retention
For material you want to retain beyond the exam, use spaced repetition to review key concepts at increasing intervals. This is particularly important for cumulative courses and professional programs where you build on previous knowledge.
These methods are built for coursework, but the same machinery works on anything you read by choice. If you want somewhere to point it, our list of books worth reading during college covers the reads that tend to outlast the syllabus.
How Chapterly Supports the Best Study Methods
The most effective study methods, specifically spaced repetition and active recall, are also the hardest to implement consistently on your own. Tracking when to review hundreds of concepts across multiple courses is a logistical nightmare. Chapterly automates this by scheduling your highlight reviews at scientifically optimal intervals. Save the key passages from your textbooks, lectures, and study materials, and Chapterly ensures you review them at exactly the right time to maximize retention while minimizing study time.
Stop spending hours on study methods that science says do not work. Build your system around the techniques that produce results, and let Chapterly handle the scheduling.
Frequently Asked Questions
What is the single most effective study method for college students?
Practice testing — closed-book retrieval of the material you are trying to learn. The 2013 Dunlosky et al. review of ten common study techniques rated practice testing and distributed practice as the only two with "high utility" across subjects, ages, and material types. Everything else, including the universally beloved highlighting and re-reading, ranked moderate or low. If you change one habit this semester, replace your second re-read with a closed-book quiz.
How is "active recall" different from regular flashcards?
It is not different in principle, but most students use flashcards passively — flipping the card, recognizing the answer, and moving on. Real active recall requires you to commit to an answer in your head before flipping the card and to mark cards you missed for more frequent review. Without that commitment-and-correction step, flashcards collapse back into recognition, which research shows produces almost no learning. See what is active recall for the full mechanism.
Is the Pomodoro Technique a real study method or just a productivity hack?
Pomodoro is a session-structuring tool, not a learning technique. It will not improve retention by itself, but it pairs well with the Tier 1 methods because forced breaks naturally distribute practice across the day. The mistake students make is treating "did 8 pomodoros today" as evidence of learning. Eight pomodoros of re-reading still produces re-reading-grade retention.
How many hours per week should a college student spend studying?
The often-cited "2–3 hours of study per credit hour" rule is roughly right if you are using high-utility methods. With low-utility methods (re-read, highlight, recopy), no amount of hours will fix the problem — students who study 30 hours a week with bad methods routinely underperform students who study 10 hours a week with good ones. Hours are an input. Retention is the output. Optimize the conversion ratio.
How does spaced repetition apply to courses I am taking now, not just exam prep?
Spaced repetition works during the semester, not just before exams. The cleanest workflow: every time you encounter a new concept (lecture, reading, problem set), capture a one-sentence retrieval prompt for it. Review the day's prompts that night, then again at increasing intervals. By exam time, most of the material is already stable in long-term memory, and your "exam prep" is just a final pass through cards you flagged as shaky. This is exactly what Chapterly automates for material you read.
What if my professor's exams are mostly memorization-heavy?
Then practice testing is even more important. The mistake students make on memorization-heavy exams is more re-reading; the right move is more retrieval. Self-quizzing with active recall is by far the highest-yield activity for any test where you need to produce information from memory. See how to remember what you study for a course-by-course retention workflow.
Chapterly turns your course reading into spaced retrieval prompts automatically, so exam prep is a final pass instead of a re-read. Try it free.
