My personal opinion is that reservation at any level is not good. Effort should be made to give the same quality of education to backward junta as the city bred students have access to. But I know that it is impractical in India considering the motivation level of most government employed teachers.
We have to remember that the purpose of reservation is to mould our society into an ideal society where reservation is not required. But with the present reservation system one can never be sure about when to stop it(the reservation system). So I have this idea where every SC and ST candidate has the oppurtunity to use the benefits of reservation limited number of times (say two times) and his succesors will not have access to these benefits if he has used all his oppurtunities. If one doesn't use all his oppurtunities, they can be passed on to his successors. In this way every person from backward caste can use the benefits of reservation and at the same time the reservation policy fades away slowly. I strongly feel that this system will help us remove reservation system and at the same time help in uplifting the quality of harijan's life.
I am not sure about the practicality of my idea.But I am looking forward to your take on reservation system and your ideas on how to eliminate the necessity of reservation system.
P.S. I myself am benefactor of reservation system and therefore I am not speaking out of malice or prejudice towards backward caste people.
