Active Recall vs Rereading: Which Study Method Actually Works?

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

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

1. Read a chapter or section once, actively taking notes (in your own words, not copying).
2. Close the book and do blank-page recall: write down everything you remember.
3. Check what you missed. Note the gaps.
4. Do 20-30 MCQs on that topic the same day.
5. Review only the questions you got wrong, not the whole chapter.
6. Two days later, do another short set of MCQs on the same topic without re-reading (spaced retrieval).
