If cbsc school is not there in hilly area, with domicile, is it possible to get admission in hilly Quota

You need to mention your state in the question. I am assuming that you are from Maharashtra.  As per the Maharasthra Hilly Area Reservation rules, “Domicile Certificate of the parent stating that he/she is domicile in the village declared as a Hilly area is mandatory. The candidate should pass SSC/HSC (or equivalent) examination from School/Junior College situated in the hilly area of his/her parents domicile or if not so, at the most, from a School/Junior College situated in the taluka of his/her parent’s domicile.”
