Maybe you should give a bit more information about your criteria of a good school. What things are a deciding factor in your choice? Academics, job prospects, prestige, cost etc? Can you also share some of your statistics such as your marks, how much research you did etc?
I know some people who have gone to IIT, Indian Institute of Science and University of Delhi for physics and they said it was a very good environment there. Those universities (I think) have a good reputation as well.
