BPT looks really easy, trust me it isn't at all. People say it's just massage and exercise, it's not really that it's physical medicine and rehabilitation that includes many treatment modes, and exercise is a key component, not massage. You'll have to look for a college that has a good hospital and speciality centres. In the fields of Anatomy[ cadaver research included], ICU and various intensive care, and so on, you will need good exposure.
Few colleges I recommend would be :
Manipal University (Best)
CMC Vellore.
