Haha ! Thats a lovely question. Dear you can learn anytime anywhere Hindi. If you are a medical student, i would recommend you to learn the language because a major part of North India as well as Central and North East communicate with this language other than their regional.

Hence, if you get a chance to go PG or Job in these areas, it will be easier to understand and advice the patients.

Now coming to Jipmer, there will be a major number of students having mother tongue Hindi so i think its the best time to learn this lovely language.
