Hi guys i am are doing BBA from sikkim manipal university i was wondering that is it a good university to pass out from and moreover you are doing correspondence Advise please?

Well if you want do to bba & then pursue MBA, I would recommend you to take admission in IIPM, it's one of the best b-school in India, & the degree will be priceless & accepted worldwide (It's not cheap)
But if you are looking for a cheap & recognized university then go for IGNOU....
