Somehow BITS has managed to get the tag of ALMOST-IIT, so anyone from IIT automatically becomes better than you in social comparisons; no branch, no institute or no quota needed, IIT>BITS. That is how people think.
BITS is a private university, so you will have a small campus(relatively) and not much funding, besides relatives will ask if you could not manage to get into any government engineering college.
Getting CGPA is damn tough, because there are no reservations, but people think that being private university, BITS must be giving out grades like anything. THAT IS ABSOLUTELY FUCKING WRONG.
Another disadvantage of Pilani Campus is the harsh weather, in Hyderabad Campus Summers are just terrible, I’ve been a victim of it.
