Why only these three colleges? None of them is that good, do you think you don't deserve better? Apply to Woxsen School of Business, Hyderabad. Compared to IBS' 1200 students, they have only 240 students, so great grooming provided to students. 

They have globally acclaimed faculty members, most of them from IIMs. the placement is 100% with many students getting 2-3 offers. The average package is much higher than all the colleges you mentioned, at INR 8 lacs per annum. So Woxsen is obviously a league apart from all these colleges.

If you think of PGDM, think Woxsen.

There's no need to be confused among these colleges as IBS Hyderabad is a far better option than the rest two in terms of pedagogy, Placements, Infrastructure and a brand name.
