I want to do distance mba. 4 yrs work-ex. Whic is a gd institute to add value to my career? Symbiosis / Sikkim Manipal?

I think you should do MBA not PGDM as after mba you can go for the further study (like PHD) if you want to go in teaching career or if you don't want to go in teaching line then also MBA is always preferred

both try to sort ur self which modules suited u most to interact with their counselors

smu is also a best option and ignou is also good as it also provides degree and symbosis gives u diploma

Symbiosis is reputed university for distance learnig in MBA. You can go for Symbiosis
