Dear Sarita, all professional studies no matter what they might be, are always taught in English. The regional medium of instruction cannot be applied in professional studies. This is because as a Medical Student post your studies you do not cater to a certain geographical patients. And it is not possible to teach certain terminologies in any other language other than in English because of their scientific names asociated. For example Salmonella Typhi cannot be translated to any other language. It has to remain like that.
