Active Recall vs Rereading: Which Study Method Actually Works?
Research is definitive on active recall vs rereading: testing yourself on material produces far better long-term retention than reading your notes again. Here is why, and how to apply it.
Active recall vs rereading is not a close contest. Rereading creates an illusion of knowing because the material looks familiar. Active recall forces retrieval, which strengthens memory pathways and makes recall easier over time. For MDCAT and ECAT students, this means MCQ practice banks and blank-page recall are more valuable per hour than re-reading chapters.
Active recall vs rereading is one of the most researched questions in cognitive psychology, and the answer has been consistent for decades: active recall wins by a wide margin. If you are spending most of your study time re-reading your notes and textbooks, you are likely working harder than necessary while retaining less than you could. This post explains why rereading fails, why active recall works, and how to apply it specifically for MDCAT and ECAT preparation.
Why rereading feels productive but is not
Rereading does not work because it trains recognition, not recall. Exams require you to produce the answer without the page in front of you, and rereading never practises that. When you re-read a chapter you already went through, it feels familiar. That familiarity is comfortable. It feels like knowledge. The problem is that familiarity and recall are completely different things. Recognising information when you see it on the page is not the same as being able to produce it on command during an exam. The feeling of productive studying that rereading creates is largely an illusion, and cognitive psychologists call this the "fluency illusion" or the "illusion of knowing."
The result is that students who reread feel prepared but underperform when the page is no longer in front of them. They could identify the right answer in a textbook. They cannot produce it in an exam hall.
Why active recall works: the testing effect
Active recall works through what cognitive psychologists call the "testing effect" or "retrieval practice effect." When you attempt to retrieve a piece of information from memory, even unsuccessfully, you strengthen the neural pathway for that memory. Each retrieval attempt makes the next retrieval faster and more reliable. The struggle of not remembering something is not failure. It is the mechanism through which learning actually occurs.
This is why doing MCQ practice banks is not just testing yourself. It is also one of the most effective ways to learn and retain the material. Every question you attempt, right or wrong, strengthens memory more than reading the same information passively.
How to apply active recall in your MDCAT or ECAT preparation
- After reading a section of a chapter, close the book and write down everything you remember. Do not look at the text. This is the simplest and most effective form of active recall.
- Use flashcards. Write a concept, formula, or reaction on one side. Test yourself before flipping. Spaced repetition flashcard apps like Anki schedule cards at the optimal interval for retention.
- Use an MCQ practice bank for MDCAT and ECAT. Each question is a forced retrieval attempt, and the feedback (correct or incorrect) tells you which concepts are not yet solid.
- Before looking at your notes, ask yourself: what was the main point of this chapter? What formula or concept does this topic hinge on? Articulate the answer before checking.
- Teach it. Explaining a concept out loud as if teaching another student is one of the strongest active recall methods. If you cannot explain it simply, you have not learned it yet.
Comparing active recall vs rereading on what matters
| Method | Effort required | Long-term retention | Exam-day recall |
|---|---|---|---|
| Rereading | Low | Low | Poor |
| Active recall (MCQs, flashcards) | Medium to high | High | Strong |
| Blank-page recall (write everything you remember) | Very high | Very high | Strongest |
The discomfort of not being able to remember something is the feeling of your brain forming a stronger memory. Do not avoid it by looking at the answer immediately. Sit with the uncertainty for a moment. Make your best attempt. Then check. That sequence is what makes active recall so much more effective than passively reading.
A practical active recall schedule for entry test students
- Read a chapter or section once, actively taking notes (in your own words, not copying).
- Close the book and do blank-page recall: write down everything you remember.
- Check what you missed. Note the gaps.
- Do 20-30 MCQs on that topic the same day.
- Review only the questions you got wrong, not the whole chapter.
- Two days later, do another short set of MCQs on the same topic without re-reading (spaced retrieval).
Frequently Asked Questions
Is active recall better than rereading for exam preparation?
Yes, by a significant margin. Decades of cognitive psychology research confirm that testing yourself on material (active recall) produces far better long-term retention than rereading. Rereading creates familiarity, which feels like knowledge but breaks down under exam conditions. Active recall builds genuine memory that holds under pressure.
What is the testing effect in learning?
The testing effect is the finding that attempting to retrieve information from memory (testing yourself) strengthens the memory more than re-exposing yourself to the information passively. Even an unsuccessful retrieval attempt improves later recall. This is the mechanism that makes MCQ practice and flashcards so effective.
How do I use active recall when studying for MDCAT?
After reading a section, close the book and write down everything you remember (blank-page recall). Then do MCQ practice on that topic. When you get a question wrong, do not just re-read the answer: try to understand why your reasoning was wrong. Two days later, test yourself on the same topic again without re-reading.
Is Anki useful for MDCAT and ECAT preparation?
Yes. Anki is a spaced repetition flashcard app that schedules cards at the optimal interval for long-term retention. It is particularly useful for memorisation-heavy topics like Biology terms, Chemistry reactions, and Physics formulas. The combination of active recall (flashcards) and spaced repetition is one of the most evidence-backed study methods available.
Why does rereading feel productive even though it does not work as well?
Because rereading creates fluency: the material looks familiar and easy to read. This is called the fluency illusion or the illusion of knowing. Familiarity feels like knowledge but is not the same thing. Exams require recall (producing the answer without the text in front of you), not recognition (identifying the right answer when you can see it).
How often should I test myself using active recall?
A practical schedule for exam preparation: test yourself immediately after studying a topic (same-day MCQs or blank-page recall), then again two days later, then again a week later. This spaced retrieval pattern takes advantage of both the testing effect and the spacing effect, two of the most robust findings in learning science.
