sir is this possible that all gs paper write in English and eassy in hindi
Yeah! UPSC now offers the options in which you can write the GS papers in English and the optional papers as well as the essay paper in Hindi. So no need to worry about this. Also if you want you can choose your interview medium in Hindi even if you have given the Mains in English. But for the interview the reverse isn't applicable.
