MBA/PGDM

As far as the online information for a online institute goes, no. IT seems to be only ISO certified.

What you want to do further will only depend on 2 things (ALWAYS)
1) What you did till now
2) What you want to do in future. Think of yourself as a passenger waiting for a bus at a stop. So either you don't get a direct bus and have to change buses or you might get a direct bus. Either ways if the destination you want to reach is known to you, then everything else will fall in place.

Divya, there's no best one among MBA specialisations. As all these specialisations have equal and vast opportunities. So please choose the specialisation which you are more interested. I prefer MBA in retail management or supply chain management, Finance, HRM, etc.

As you have just prepared for it, so don't worry, everything is going to be fine.
Good luck.

IITTM would be the best choice for you. Check out their website.

Placements are provided by the college to the students. Yes, it's worth it to do PGPM+MBA from there.
Good luck.

Yes, they offer MBA in information technology and the duration of the course is 2 years.

Yes, there are many colleges affiliated to AKTU to pursue MBA like KIET, RKGIT, JSS, etc. They offer admission without CAT exam.

IIMT University, Meerut is good for MBA, not for BBA due to its placement factor.
