Spaced Repitition
Spaced repitition is a learning technique in which topics are reviewed at increasing intervals.
The idea is that by spacing out the reviewing of information, it is reviewed at (ideally) exactly that point in time at which you’d forget it. Therefore it is harder to recall the information, which in turn causes it to be retained better.
Example intervals can be: 1 day, 3 days, 1 week, 1 month, 3 months.
Reviews in spaced repitition should be combined with active recall.
