Hello Ayush,
There is no standard yardstick to measure performance of these coaching institutes. Authenticity of the adverts placed by these institutions in newspapers is unverified. Hence one had to take it with a pinch of salt. Having said this, it still remains open as to where to go. I will advise you to select that institute in which you have more faith.

There is only one college which is decent but not great named as PR Patil College, you can get details below.

Dear,
There is no change in the degree name whether it is a BA or B.Sc in psychology. The only difference is the name of the degree from different universities. And if you want to become a psychologist then you have to complete your Masters in clinical psychology and then M.Phil in the same.
After that only you would get the license from RCI.
All the best.
