Techniques to enhance effective note-taking for UPSC topics include employing the SQ3R method (Survey, Question, Read, Recite, Review) for structured comprehension. Utilizing bullet points for key ideas, creating mind maps for visual representation, and maintaining a consistent format can improve retention. Additionally, summarizing information in one’s own words encourages a deeper understanding of complex concepts. Regularly reviewing and updating notes ensures retention over time, while integrating relevant diagrams or charts can enhance clarity, making notes a more effective study resource.
