Excuse me? the students in your school must be pretty dumb and arrogant to tease someone based on caste while studying 10th standard. This is exactly why the playing field must be leveled. The historically oppressed need more support to uplift themselves and reservation has helped millions of Dalits and other backward caste people, in spite of some narrow minded forward caste people's opposition.
Contrary to many of your claims, I have seen many students who entered my school through reservations do extremely well .
