When approaching answer writing for the UPSC Mains exam, candidates should prioritize clarity and structure. Begin with a succinct introduction that encapsulates the main point, followed by a coherent body that presents relevant arguments or examples. Use headings and bullet points for better organization. Lastly, conclude with a strong statement that summarizes the answer. Adopting a methodical approach ensures that answers are not only comprehensive but also engaging, allowing evaluators to assess candidates progressively.
