Make It Stick
Peter C. Brown, Henry L. Roediger III & Mark A. McDaniel
Make It Stick argues that the study habits that feel most productive are among the least effective. Those habits are rereading, highlighting and cramming one topic at a time. Drawing on decades of memory research, the authors show that effortful techniques such as retrieval practice, spacing and interleaving build learning that lasts. It is one of the most practical evidence-based books on how to study.
Maybe you have reread your notes three times, felt ready, and then gone blank in the exam. This book explains exactly what went wrong, and it wasn't your intelligence.
The book in essence
Three people wrote the book. Peter C. Brown is a writer. Henry L. Roediger III and Mark A. McDaniel are cognitive psychologists at Washington University in St. Louis. They weave lab findings together with stories from pilots, surgeons, athletes and students, so the research reads like everyday life rather than a journal article.
The central idea is simple and uncomfortable: material that feels familiar is not the same as material you have learned. Fluent reading creates a feeling of knowing. What actually makes learning durable is the effort of pulling information out of your own memory. The authors build on psychologist Robert Bjork's idea of 'desirable difficulties', which describes methods that slow learning down on the surface and deepen it underneath. The book also says plainly that tailoring teaching to 'learning styles' lacks strong evidence.
To be honest, the book repeats itself in places, and the core techniques fit on a single page. Its real value is in convincing you to put up with the discomfort these techniques bring. They feel bad while you are doing them. The book's job is to show, with evidence, that this feeling is a sign of progress.
Who it's for
- Students preparing for high-stakes exams
- Professionals learning a language, a coding skill or a certification
- Teachers and trainers who want to design more effective lessons
- Anyone who notices they forget what they read within days
Who it's not for
- — Readers looking for a ready-made, step-by-step study schedule or an app workflow
- — People already well versed in retrieval and spacing research, who will find little that is new
Key lessons
01
Familiar isn't learned
When you read a text a second or third time, the sentences flow, and your brain reads that fluency as 'I know this.' But that is recognition, not recall. In an exam, a meeting or on the job, the page isn't in front of you; you have to produce the knowledge yourself. Highlighting feeds the same illusion: the page gets colourful while your mind barely changes. The first lesson is to tell the difference between feeling ready and being ready. The only reliable test is to explain or apply the material without looking.
A nursing student rereads her pharmacology notes until every page feels obvious. Then a classmate quizzes her on drug side effects with the notes closed, and she can name only a handful. From then on, she closes the notes after each section and explains it out loud before checking.
02
Close the book: retrieval practice
Trying to pull an answer from memory before looking leaves a far stronger trace than rereading the same material. Researchers call this the testing effect, or retrieval practice. Here a test is a learning tool, not just a way of measuring. Give yourself small, low-stakes quizzes: use flashcards, write what you remember on a blank page at the end of a chapter, or explain the topic to a friend. Struggling to recall is not a bad sign; that effort is what strengthens the memory. If you get something wrong, check the right answer straight away. Corrected errors are part of learning too.
An accountant studying for a professional exam stops rereading chapters in the evening. After each section she writes five key concepts from memory, and only then opens the book and marks what she missed in red. Three weeks later, her practice-test scores are clearly higher.
03
Space your reviews
Studying a topic today, again in three days, in a week and in a month beats studying it ten times in one night. A little forgetting in between is part of the process. Recalling something you have half forgotten rebuilds the memory more firmly each time. Cramming seems to work in the short term, but the knowledge fades within days. That is why spaced repetition sits behind language learners, medical students and apps like Anki. Several small, scattered review sessions on your calendar do more than long, intense ones.
Someone learning Spanish for a new job gives up memorising 200 words every Sunday and switches to 15-minute daily sessions. Each new word gets quizzed again the next day, three days later and a week later. Two months on, most of the first list is still there.
04
Shuffle the deck: interleaving
Working through every problem of one type in a row feels smooth and satisfying, because you already know which method each one needs. Real life and real exams don't label their problems. Mixing problem types (interleaving) feels messier and slower, but it trains the skill that matters: recognising what kind of problem is in front of you and choosing the right method. In studies, people who practise in blocks look better during practice, while people who practise mixed problems do better on later tests. The hard part is that the progress stays invisible while you are working.
A maths teacher used to give one topic per week of homework. Now each worksheet mixes problems from three topics in random order. Students complain at first. By the end-of-term exam, they are much quicker at spotting the problem type and switching to the right method.
05
Design your own learning project
The book's techniques work best together. A strong learning project cycles through three steps. First you do the real skill. Then you drill the one weakness that limits it most. Finally you test what actually stuck. If you are learning guitar, you play the song, practise the chord change you keep fumbling on its own, and a week later try the song without the sheet. Make the goal measurable: instead of 'learn Spanish', aim for 'chat comfortably with a waiter within three months'. Then judge your progress by test results, not by how you feel.
An operations analyst wants to learn data analysis in Excel. Each week she builds a report from her company's real sales data. She spends an extra 20 minutes on pivot tables, her weakest point. At month's end she builds a report from scratch without help, and wherever she gets stuck shapes next month's plan.
Try this today
Pick something you studied this week, close the material, and spend 10 minutes writing everything you remember on a blank page. Then open it and mark what you missed. Those gaps are your next study session.
