The choice of B Schools depends on your interests and priorities. The school you choose depends on

• What you want from your MBA degree
• How much you are willing to invest

Some people consider placement statistics for making their decision but personally I find that a bit misleading. One other good way is to talk to the alumni of the schools and make a list of pros and cons. This will help you analyze the worth of each college and thereby make a sound decision.

Every B School has a specialization. You need to identify that and match it with your own goals and aspirations. For example, 

IIM Ahmedabad is known for its strategy, IIM Bangalore is known for its marketing, IIM Calcutta is known for its finance, and FMS is known for its high ROI and location (Delhi). 

So make a choice that suits your inclinations and don’t adopt the sheep mentality.
