Candidates can devise strategies to tackle complex questions in UPSC by adopting a systematic approach. First, they should break down questions into components to understand what is being asked. Utilizing a framework for responses, such as introduction, analysis, and conclusion, can help organize thoughts better. Moreover, practicing time management during mock tests enhances their ability to respond effectively under pressure. Regular revisions and discussing questions in study groups can also stimulate new ideas and perspectives, refining their analytical abilities to handle intricate questions.
