There are only 10 seats available in AFMC for reserved category (SC/ST) as there is no such cut off for the same and their selection process is given below -

"(a) The SC/ST candidates must have applied to AFMC Pune and also qualified in the NEET - 2017 written examination and should have come within the zone to be called up for interview.(b) If shortlisted and called for the screening at AFMC, they must come within the first 500 in the final combined merit list of boys and girls. (c) They must fulfill all other conditions/standards, as applicable to non-SC/ST candidates, like age eligibility, academic qualification, medical fitness, etc. (d) These reserved seats will be in addition to any vacancies secured by SC/ST candidates on the basis of their position in the merit lists.
