Regional languages can significantly affect UPSC examination performances in India, particularly for candidates who are more proficient in their regional language than in English. Those who attempt to comprehend complex topics and intricate texts may struggle if they are not well-versed in English. Additionally, language proficiency impacts reading comprehension, which is vital for both the Preliminary and Main exams. While some candidates may feel at a disadvantage, effective preparation through bilingual resources can mitigate these challenges, allowing for better understanding of diverse examination topics.
