Dear Riya, The 100 seats available for CMC Vellore MBBS admission are broadly divided into the open and sponsored caregories. 16 seats are open to all categories - 20% or 3 seats within the open seats have been reserved for Scheduled Caste/Scheduled Tribe and 1 seat has been reserved for the Central Pool Scheme nominated by the Government of India. The remaining 84 seats are filled by sponsored candidates. Depending upon which denomination does Christianity come under either in Tamilnadu or Punjab, reservations are applicable accordingly. In general not just Christians but every aspirant who meets the eligibility criteria, is eligible for trying to get a seat in CMC or Ludhiana.
