Language proficiency significantly affects UPSC exam performance, as clear expression can influence both written and verbal assessments. Good command over the language enhances clarity in answer writing, aiding in conveying complex ideas effectively. Additionally, strong communication skills are vital during the interview stage, where articulation and confidence matter. Proficiency in multiple languages can also be an asset, helping candidates relate better to diverse socio-cultural contexts. Thus, honing language skills is an integral part of an effective preparation strategy.
