Methods that can enhance creative thinking for the essay component of the UPSC include brainstorming sessions, mind-mapping, and free writing. Engaging in brainstorming allows candidates to generate a multitude of ideas without judgment, fostering an open creative environment. Mind-mapping helps structure these thoughts visually, linking concepts in a format that facilitates further exploration. Free writing encourages unfiltered expression of thoughts, breaking mental roadblocks that may inhibit creativity. Furthermore, practicing varied prompts and styles can diversify candidates' thought processes, enabling them to approach essay topics from unique angles and ultimately producing more compelling narrative flows.
