Ask Clear Admit

I have the following profile, and would like to have it evaluated by you:

GMAT: 740
GPA: 6.8 on a scale of 10 (frankly, quite mediocre in my college)
Doing my Undergrad in engineering from a Top-10 engineering institute in India
Extras: I was a national level sportsman, and have won numerous individual gold medals at the national level
I have been selected to represent the country in (and will be attending) the 5th World Youth Congress and the 20th International Youth leadership conference this July
I am an active member of the marketing team of the Indian Youth Climate Network
I am the batch representative & active member of my college debating team
I am the manager of the master of ceremonies (MOC) team at various fests in college

I am extremely interested in social entrepreneurship, and have interned at a startup social enterprise for a month before. I intend to do a fellowship (roadtrip for social change) and a project on social entrepreneurship under a suitable professor this summer.

Anyway, that's the long & short of my profile. I intend to apply for an MS in management in top European B-schools and some select MBA programmes in the US which encourage early career applications. What would you suggest? And would you suggest I do some a good course in a quantitative subject to better showcase my academic abilities?

Thanks in advance
