SG: kindly allow me put across one point- there are several centres like Kota, Rajkot which are hubs of competitive exams. The word which is being used by the newspapers- 'Factory' is possibly taken from the web series 'Kota Factory'

SG: Kota in Rajasthan, Rajkot in Gujarat, Nammakal in TN ...seevral centres and hostels, the entire economy is centred on students, there are question papers given everyday, when the child sits for the actual examination actually it is their 200th examination
