There is not a single good English medium school in India which prohibits dalits to take admission, we all stay in INDIA and we are also aware of Indian reality. Even if there is any, proper way is to file complain against schools and bring this issue to media. And I think you are asking reservation at wrong place, you should ask for reservations in temples, water wells and barbers shops, where as per you dalits are prohibited, reservations in IIM and IIT will not solve this problem. Proper solution this is to provide basic and good education not only to dalits and pandits but to all. Which is still lacking behind and no one ever thinks of it. At present this caste system is only limited to rural India but with reservation you will spread it across the country.
