I got selected in IBS Mumbai. Is there a chance for to swap my campus to IBS Hyderabad? I have gotten an 85 percentile.

I don’t really understand why you want to change campuses when the Mumbai campus is the most coveted one. I have a friend who despite being an IBS Hyderabad pass-out, considers the Mumbai campus way superior after spending months on a summer internship there.

He considers the IBS Hyderabad to be overestimated and apart from infrastructure, IBS Powai/Hiranandani is much better in all aspects. Moreover, the Mumbai campus enjoys the locational advantage of being closest to the city of dreams. The campus is in the vicinity of IIT Mumbai so you get to interact with many geniuses also. 

On the other hand, IBS Shankarpally, despite having top-notch infrastructure, lacks connectivity. You are disconnected from other students and the entire world if you choose this college.
