Effective note-making during UPSC preparation involves several best practices to enhance retention and comprehension. Aspirants should adopt a structured format, such as the flowchart or mind map, which allows for visual representation of connections between topics. Utilizing bullet points facilitates quick reference and clarity. It's essential to paraphrase rather than transcribe, ensuring active engagement with the material. Regular revision of notes and incorporating colors or symbols can enhance recall. Lastly, summarizing chapters in one's own words helps reinforce understanding and provides concise revision material for future reference, aiding in exam readiness.
