To improve answer presentation in the UPSC Mains exam, candidates should focus on structuring their responses clearly. Using a three-part format, which includes an introduction, body, and conclusion, helps make answers cohesive. Additionally, employing bullet points can improve readability, while highlighting key terms and using real-life examples can enhance arguments. It’s also valuable to practice writing within the word limit and to refine handwriting for clarity. Furthermore, time management during the exam ensures that candidates can cover more questions effectively.
