The study method most students overlook
If you ask a college student how they study, the answer is almost always the same: flashcards, re-reading notes, or highlighting textbooks. These methods feel productive. You recognize the material, you feel like you "know it," and the repetition is comforting.
But there is a problem. Cognitive psychologists have spent over a century studying how memory actually works, and the evidence is clear: recognition is not the same as recall. Feeling like you know something and being able to produce the answer on an exam are two fundamentally different cognitive processes.
This is where practice testing enters the picture. And the research supporting it is not a handful of small studies. It is one of the most replicated findings in all of learning science.
What the research shows
In 2013, cognitive psychologist John Dunlosky and his colleagues published a landmark review in Psychological Science in the Public Interest. They evaluated 10 common study techniques and rated each for effectiveness. The results surprised a lot of people.
Practice testing (taking quizzes or practice exams on material you are trying to learn) received the highest utility rating. Flashcards, as a form of simple self-testing, received a moderate rating. Re-reading and highlighting received the lowest.
Key finding: Dunlosky et al. (2013) rated practice testing as a "high utility" study technique, effective across ages, subjects, and testing formats. Re-reading and highlighting were rated "low utility."
This finding builds on decades of prior research. In 2006, Roediger and Karpicke demonstrated what psychologists call "the testing effect." Students who took a practice test on material retained significantly more than students who spent the same time re-studying. The difference was especially pronounced after a delay, meaning practice testing produced more durable, long-lasting learning.
Why practice tests work better
The key mechanism is something researchers call retrieval practice. When you take a practice test, your brain has to actively reconstruct the answer from memory. This effortful retrieval strengthens the neural pathways associated with that knowledge, making it easier to access next time.
Flashcards also involve retrieval, but with a crucial difference: the type of retrieval matters. Flashcards typically test isolated facts, such as a term and its definition. Practice tests, by contrast, require you to apply knowledge in context, connect ideas across topics, and think at a higher cognitive level.
Consider the difference between these two tasks:
- Flashcard: "What is mitosis?" (Recall a definition)
- Practice test: "A cell has a mutation that prevents the formation of spindle fibers. Which phase of mitosis would be most directly affected, and what would happen to the daughter cells?" (Apply knowledge, analyze a scenario)
Most college exams test the second type of thinking, not the first. That is why students who study only with flashcards often feel prepared but underperform on the actual test.
Head-to-head comparison
| Factor | Flashcards | Practice Tests |
|---|---|---|
| Best for | Vocabulary, definitions, isolated facts | Application, analysis, connecting concepts |
| Cognitive level | Recognition and basic recall | Higher-order thinking (Bloom's apply, analyze, evaluate) |
| Exam simulation | Low: does not match exam format | High: mirrors the actual test experience |
| Feedback quality | Binary: right or wrong | Detailed explanations, identify weak areas |
| Anxiety reduction | Moderate | High: familiarity with test-taking conditions |
| Time efficiency | Fast per card, but many cards needed | More time per question, but deeper processing |
| Research rating | Moderate utility (Dunlosky, 2013) | High utility (Dunlosky, 2013) |
When flashcards still make sense
This is not a case where one method is always wrong. Flashcards are genuinely effective for certain types of learning:
- Foreign language vocabulary where you need to memorize pairings
- Anatomy terminology where the goal is pure recall of names
- Historical dates or other factual data points
If your exam is purely definitional (matching terms to definitions, fill-in-the-blank vocabulary), flashcards can be the right tool. But most college courses, AP exams, and professional certifications test application and analysis, not just recall. For those assessments, practice tests are the better investment of your study time.
The real problem: students do not have easy access to practice tests
Here is the practical challenge. Most students know that doing practice problems is helpful. But finding good practice tests from your specific course material is hard. Textbook question banks often do not match what the professor emphasizes. Old exams are not always available. And writing your own questions is time-consuming and limited by your own understanding of the material.
This is one reason flashcards dominate: tools like Quizlet make them effortless to create and share. The convenience advantage is real, even if the learning advantage is not.
Turn your notes into practice exams in seconds
Upload your PDFs, lecture slides, or notes. RaiseMyGrade generates practice exam questions from your actual course materials, with detailed explanations and weak area tracking.
Try RaiseMyGradeA better study workflow
The most effective approach combines both methods strategically:
- Start with flashcards for the foundational layer. Learn the key terms, definitions, and formulas you will need.
- Switch to practice tests once you have the basics down. This is where you build the deeper understanding that exams actually test.
- Focus your review on the topics where practice tests reveal gaps. Do not waste time re-studying material you already know.
This approach works because it matches each method to its strength. Flashcards handle the memorization layer. Practice tests handle the application layer. Together, they cover the full spectrum of what your exam will ask.
The bottom line
If you have been studying primarily with flashcards and your exam scores do not reflect the time you are putting in, the research suggests a clear next step. Add practice testing to your study routine, ideally using questions based on your own course materials.
The testing effect is one of the most robust findings in cognitive psychology. Students who test themselves learn more, retain more, and perform better on exams. The science is settled on this point.
The question is not whether practice testing works. It is whether you have access to practice tests from your actual study materials. That is the gap tools like RaiseMyGrade are built to fill: upload your notes, get a practice exam, and identify your weak areas before the real test.
