Effective revision requires preparation, organization, and using study techniques that promote understanding and repetition. Some key strategies include creating a revision timetable to space out topics, using interleaved practice to revisit each topic several times, and employing multi-sensory techniques like mind maps, flashcards, and teaching concepts to others. It is also important to get sufficient sleep and manage stress to allow for optimal memory and focus during revision. Regular self-testing helps identify weaknesses to address and reinforces learning over time.
