“Rereading can create fluency without mastery; retrieval shows you what you actually know.”

The book reframes testing as learning practice. A blank-page recall attempt exposes gaps and strengthens the route back to the idea.

“Difficulty is not a sign that learning is failing; it is often the condition that makes learning durable.”

Spacing, interleaving, and generation feel inefficient in the moment because they force reconstruction instead of recognition.

“Practice works best when it trains judgment, not just repetition.”

Mixing related problem types builds discrimination. You learn when to use a method, not only how to repeat it.

“Feedback matters most after effort has made your current model visible.”

Trying before checking turns correction into targeted information. The mistake becomes a map of what needs repair.

“The learner who feels slower during practice may be building knowledge that lasts longer.”

Performance during a session can be misleading. The better question is what remains accessible days or weeks later.
