Andhra University, Visakhapatnam

If you qualify AUEET, you are eligible to get a seat in Andhra University. Admissions are done through both the exams.

Yes, but make sure that by qualifying in AUEET you are going to dual degree course. Anyway, I think there is a provision for quitting the course after completing your 8th semester and to get a B.Tech certificate. But be sure about it. It's better to contact AU admissions desk for more information.
