Vocabulary significantly impacts performance in the UPSC examination, as it influences clarity and expression in both written and verbal components. A robust vocabulary enables candidates to articulate ideas succinctly and precisely, enhancing overall communication. It is especially crucial in the essay and interview stages, where the articulation of complex concepts is essential for impressing evaluators. Additionally, an extensive vocabulary demonstrates familiarity with various subjects and current affairs, reflecting deeper understanding. Regularly engaging with reading materials, such as newspapers and quality literature, aids in expanding vocabulary, which in turn, can positively influence exam outcomes.
