Well-rounded candidates can differentiate themselves in the UPSC examination by focusing on holistic development. This includes a strong grasp of current affairs, sharp analytical skills, and public-speaking abilities. Candidates should showcase their understanding of various subjects instead of rote memorization. Personality development is also key; candidates should exhibit a deep sense of ethics, integrity, and social awareness. Engaging in extracurricular activities or community service can enhance their profiles. Continuous self-assessment and practice lead to greater confidence and a better performance in the examination.
