Hello Gaurav,

I suggest you to opt for languange courses only if you have a personal interest in learning languages. In my opinion, it does not add much value in shaping a career in MBA. Nevertheless, it will definitely be a value addition to your profile.

You can go for certification/ courses like Lean Six Sigma, Design Thinking, Google AdWords, Web Analytics etc. to shape your career in MBA.

Language courses help you in obtaining a CV point and they can be really helpful if you go on an international exchange program.
Otherwise its always good to know a foreign language when you are doing MBA just for a fact that there may be opportunities when you would have to go to soe foreign country so the language that you learn may come in handy at that time.
