Hey Nagalla,

This year DU has Received Nearly 3 Lakhs application for admission. So you could compare it's popularity from itself. 

Its doesn't matter Where You do your BA or BSc Or Btech from. Only thing matter is your knowledge. And when it comes to DU it's more about the prestige of studying in India's most tough to enter colleges. A marksheet from IIT Or IIM Or DU has there importance in itself. Its Cuz getting in this institution is hard as hell.

So if you think Telengana is a better choice then go ahead.

Best of Luck
