To develop a strong answer-writing technique for UPSC Mains, candidates should focus on structure, clarity, and relevance. Begin with a clear introduction outlining key points, followed by concise, well-organized paragraphs that explore each aspect in detail. Use appropriate examples to substantiate arguments, ensuring answers are analytical rather than descriptive. Practice writing answers within designated time limits to simulate exam conditions. Regular feedback from mentors or peers can highlight areas for improvement. Ultimately, refining technique through consistent practice enhances performance in the examination.
