Hi,

For MA political science the medium of instruction i.e the teaching and lectures will be in English Language but you can write your exam in either English or Hindi. It totally depends on you if you want to undertake this course as even though the teaching will be in English but you are free to write your exams in Hindi, and for any further information about the course i have attached a link for your reference
