MBA/PGDM

IGNOU does not provide IT specialization in MBA. Currently specializations in HR, finance, operations, marketing and financial markets is offered by IGNOU for MBA students.

There isn't a specific criteria, because you get a call on the basis of your profile. There is a psychometric test followed by gdpi and accordingly you will convert it based on the preference with Core specializations having tougher competition. Hope you got my point, all the best :)

The placements of Taxila is much better, even the student are getting placed before 6 months of PGDM completion.

It is one of the best college in India, if the placement is your priority.

Some major government and private firms do not accept double major.

They can make & check their own question paper. Distribution of marks is also independent.
Except they can't teach or create their own syllabus.
