What are the disadvantages to pursuing mba from deemed to be universities?? This will be convert into any problems in future??
No , generally there is no advantage of persuing mba from deemed univerity. In deemed universities infrastructure, faculty, placements, are good. But not good in value of certification. Before studying in a deemed university you should check if its approved by AICTE or not . If the university is AICTE approved then there is no problem studying in it.
No problems will be occured in future regarding this.
I hope this helps.

Good luck
Since deemed universities follow their own pattern which doesn't suit to some big companies. As they follow overall trend of ugc.
