Candidates for the UPSC Civil Services Examination can choose from various languages, including Hindi and English, as well as regional languages such as Bengali, Tamil, and Malayalam. The option to select a specific language provides candidates the opportunity to leverage their linguistic strengths, ensuring they can express themselves best during the examination. Furthermore, choosing a familiar language may help reduce anxiety, allowing candidates to focus more on content and less on language barriers during both the written and oral assessments of the examination.
