The other important thing to know about Kellogg is that perhaps more than any other top school, they value do-gooder type community involvement. You didn't mention any in your profile, and without it you will be a long shot, no matter what your score is.
I am not sure if I agree with the community involvement part. Community involvement might give your application additional weightage. But not doing it does not make admission a long shot. I know atleast 5 Indians from my company who got into Kellogg with no community work whatsoever.
But if you have been involved in the community then ofcourse it will boost your application.
