Will I get a seat in St. Stephen's college? Please help me out!?

I am a tibetan buddhist and i have got 93.6% in CBSE boards PCM subject. I want to do B.sc honours in chemistry from St. Stephen's college. I've heard that 50% of its seats are reserved for Christians. Is there any seat reserved for buddhist students? is there any chance of me getting into this college on the basis of minority quota?
