Spaced practice is a revision strategy based on time. Students should spread out their revision into shorter sessions over a longer period of time. This is far more effective than cramming, referring to completing all revision in marathon sessions. Many students are guilty of cramming all of their revision just before an exam.
Timetables are useful when planning your spaced practice. This way you can organise your time effectively.
Spaced practice is not a short term task; it must be completed over a long period of time. The key is to regularly review what you know.
