Sometimes it is very difficult to prove who is economically backward. Pariticularly with business people, big farmers, shop owners--who often even if they have millions of rupees income, on the records they show only Rs 10,000 as income. I know one persone son a big Cinama Hall was getting scholarship as Economically Backward Class person.
Nevertheless, I suggest concessions in fees and hostel expenses, free coaching, for ecomonomically backward people rather than reservations.
