Aspirants can effectively utilize summarization techniques by condensing information into manageable chunks. This involves creating mind maps or brief outlines for each topic, which helps in retaining key details. Candidates can practice by summarizing articles or lectures in their own words, boosting comprehension and recall. Employing bullet points for important facts and creating visual representations for complex concepts also aids learning. Regularly revisiting and refining these summaries enhances clarity and enables quick revisions, making preparation more efficient.
