Hi Rohit

It is good to hear that you will be preparing for civil services in graduation. These are the subjects which are a part of the upsc exam:

History, Geography, Polity, Public Administration, Economics, Ecology, Environment, Science & Tech, Ethics (Philosophy/Psychology)

So, I would suggest you should go for Bachelors of Arts in any of these subjects which interests you the most. As for the college you can find the best colleges for BA here:
