This method is built around mixed practice and the researchers who measured it — Rohrer and Bjork — not around motivational slogans.
Scores in this atlas compare it with the other 23 topics on evidence, speed, effort, exam fit, retention and beginner load.
Use it on the public outline of the sitting you will actually take. This page is not a leaked paper.
