Best practices for answer writing in the UPSC Mains include clarity, conciseness, and structured presentation. Candidates are encouraged to begin with a clear introduction, followed by the main arguments, and conclude with a summarization of key points. Using bullet points or subheadings can enhance readability. It’s crucial to directly address the question and provide logical explanations, supported by facts or examples. Additionally, managing time efficiently during the exam is essential, ensuring that all answers receive adequate attention. Regular practice with feedback can help improve writing quality and exam strategies.
