How much do you remember of what you've read?
Ten questions on the key ideas of each book, with an explanation for every answer. Most people are surprised by how much has faded, and by how much comes back once they try.
Why quiz yourself on a book you've finished?
Because it's the fastest way to keep it. Trying to recall an idea, even when you fail, strengthens it far more than rereading your highlights. It also shows you exactly which ideas are slipping, so a review takes minutes instead of a weekend. Active recall explains the research; how to remember what you read turns it into a method.
Each quiz takes about three minutes. Come back a few days later and take it again from memory: that second attempt, spaced out in time, is what makes a book stick.
