MBA/PGDM

UBS will be a better option for MBA amongst the two.

You can hit on any of the management colleges, but the colleges should be interested to be hit upon. Give an entrance exam and score well.
To identify a management college, decide your location, specialisation, fee structure, ROI and placement records of various colleges.
All the best.

Alliance University, Bangalore is an average college for MBA as its fee is very high and the ROI is not good. I would suggest you to try for a better college.
