From an "interview Robert Bjork, the director of the UCLA Learning and Forgetting Lab, a distinguished professor of psychology, and a massively renowned expert on packing things in your brain in a way that keeps them from leaking out."
1. Interleaving - focus on practicing different mini-skills, rather than trying to master one skill before moving on the next.
2. Vary your study location.
3. Spaced practice. Consider "taking notes just after class, rather than during — forcing yourself to recall a lecture’s information is more effective than simply copying it from a blackboard. You have to work for it. The more you work, the more you learn, and the more you learn, the more awesome you can become."
4. Forget about forgetting.
