There are no separate colleges for admission to the wards of CRPF Personnel. According to the official notification http://bsf.nic.in/doc/misc/Allocation1.pdf there are 15 MBBS seats and 03 BDS seats allotted under BSF Quota. Once NEET results have been declared, the concerned department will also release application forms for wards applying under BSF quota. So you need to apply for the same. The admission is based through All India Counselling through a separate merit list.
