Join coaching institute. Any coaching institute except FIITJEE and Narayana should be good. But just let us know what are the coaching centres nearby. For eg @Ishita_Anand said that her coaching is bad. I thought 90% of VMC centres are good. Again I was mistaken.
There might be bad centres out there. So you need to be wary of such centres. I guess many of would know where to join and where not to join coz there are people from almost all mainland states here.
