This technique allows candidates to create a central concept, branching out into key ideas and subtopics. By creating visual representations, aspirants can establish relationships between concepts, enhancing comprehension. Mind maps encourage active engagement with materials, improving recall and retention. Additionally, they can simplify complex subjects by summarizing large amounts of information in a clear, concise format, making revision sessions more effective and less overwhelming.
