Spaced Retrieval

Spaced Repetition is like someone else giving you a push on a swing. Spaced Retrieval is when you do it all by yourself with your legs. Obviously, you are getting better at the swing when you do it all by yourself!

The same happens when you memorize. Your memory gets much stronger when you have to work hard and dig out the answer to a question. It gets much stronger when you finally find the answer at the bottom of your mind. This makes the answer as memorable as discovering a nugget at the bottom of a gold mine.

This is why The Hundred is full of quiz questions. You discover new knowledge on your quests and you win quiz questions. The AI quizzes you just at the right time when the swing is at the best point to stretch your mind. Then you dig out the answer and you end up swinging higher and higher and your memory gets stronger and stronger.
