MBA/PGDM

Definitely, the course at SITM is tailormade for students from electronics background. I too am an ECE graduate and felt very easy to adapt to the MBA course at SITM. Here, you'll not only learn technology related subjects, but the managerial and practical aspects of those subjects.

Both the colleges have their own especially. If you are from technical background and want to shape your career in a managerial role then SITM is your best bet. It has 100% placement since inception and both the batch size as well as the fee structure is on a lower side.
IFMR is famous for finance. So, if you are from non-technical background then go for IFMR.
The benefit of SITM is that it provides dual specialization with finance included in all its specializations.
Moreover, Pune is more easy to get acclimatize to than Chennai.

In IGNOU, the fee structure for MBA in HR is around INR 15000.

Students with MBA by distance learning are eligible to seek admission in regular PhD if degree is done from a recognised university or Institute. In fact you can also do PhD by distance learning from IGNOU, AIMA-Aligarh university etc.

MBA from IGNOU is really a good option. The fee structure is under INR 15000. The course is for 2 years.

Don't do it through correspondence, do it in distance mode. It will be a value addition. It is definitely beneficial.

1. Madurai Kamaraj University.
2. Anna University.
These could be the best universities for distance MBA.

You are advised to appear in XAT, SNAP, NMAT and / or IIFT to seek admission in top BSchools others then BSchools using CAT score for MBA admission.

Yes it's a 2 year course and AIMA PGDM is distance but in the certificate nothing of this sort will be mentioned. Are you currently studying in UWBS or you have taken admission only?
