I’ll just say what were all thinking: studying takes too much time.

There are only 24 hours in a day, and naturally you’d like to use as many of them as possible for sleeping and, I don’t know, drawing pictures of robot bears or something. To achieve that goal, you need to find a method that lets you spend less time studying while retaining the same amount of information.

Here’s the solution: space out your studying. By introduce time intervals between study sessions, you can remember more – even if you spend fewer actual hours studying.

This is called spaced repetition, and it may be the most powerful technique in existence for improving your brain’s ability to recall what you study.
