To improve retention of vast information, aspirants can adopt methods like the spaced repetition technique and active recall through self-quizzing. Breaking down complex topics into smaller, digestible chunks enhances understanding and memory. Additionally, using visualization techniques, such as mind maps or diagrams, can create mental associations that aid recall. Regular review sessions, spaced over time, ensure that information is consolidated in long-term memory, enhancing the aspirant’s ability to retrieve knowledge effectively during exams.
