Recalling what you have learned shortly after learning

Whether it’s a motorboat license or an instructor’s license, sometimes you have to take exams as you get older. Do you plow through the textbook again and again? That can help. But memory research shows that another practice is more effective: recalling what you’ve learned shortly after cramming. For example, by telling a friend or writing it down in your own words. In principle, distributed learning is better for the memory than cramming all at once.
