Regional languages can influence UPSC preparation for some candidates, especially those who find comfort and understanding in their mother tongue. This linguistic familiarity can enhance comprehension of complex subjects, making study materials more relatable. Furthermore, candidates may opt to take exams in their regional language, enabling better expression during the evaluation. However, proficiency in English remains crucial, particularly for essay writing and current affairs analysis. Thus, aspirants must balance regional language strengths while refining English skills for comprehensive preparation.
