Greetings, This news item on "The Hindu" clearly explains the impact these proposed changes are going to have. An excerpt of the news item and the link are pasted below. Please read through. This indicates that if an aspirant’s mother tongue is, say, Gujarati, but his language medium while studying for the first degree and writing his graduate examinations, was not Gujarati, he will not be allowed to write the exam in Gujarati. Many students study in regional languages till Class 12. Though they shift to English medium for their college education, their level of proficiency in English cannot be compared with those studying in “convents” and cities. When Hindi is allowed as a language medium for the UPSC mains examination unconditionally, why not other languages like Tamil, Telugu, Gujarati? This step is a negation to the “idea of India” that the founding fathers of the Constitution envisaged. http://www.thehindu.com/opinion/op-ed/how-upsc-got-its-english-wrong/article4519242.ece
