The process of formulating opinions teaches candidates valuable skills, such as critical thinking and analytical reasoning, essential for UPSC preparation. By actively engaging with various topics, candidates learn to assess information critically, weigh different viewpoints, and develop well-informed conclusions. This skill is particularly useful for essay writing and answers in the examination, where clear, reasoned arguments are vital. Additionally, articulating opinions helps in enhancing verbal and written communication skills, which are crucial for presenting ideas effectively in both written and interview stages of the UPSC process.
