Discrimination against lower castes is very real. There are quota to somewhat compensate for this. Maybe you interpreted it as there being quota for each caste?
Trying to understand, not interpret. Is there law allowing discrimination against lower cases? Or is there law allowing reverse discrimination to redress previous discrimination?
Sorry, I hadn't seen your message. There is a law prohibiting caste-based discrimination. For university admissions there are also quota for low caste, casteless and tribal people, meaning that a certain percentage of places is reserved only for students belonging to those groups
