Critical thinking is essential in the preparation and examination process for UPSC as it enables aspirants to analyze information critically and solve complex problems. This skill allows candidates to evaluate diverse perspectives, make informed decisions, and form coherent arguments, particularly in the mains examinations and interviews. By engaging with diverse materials and practicing articulation, candidates can enhance their ability to think independently, which is crucial in a competitive environment like the UPSC. Moreover, critical thinking fosters adaptability, helping candidates respond effectively to unpredictable questions that may arise during the exam.
