Private Medical'/Dental Colleges do not participate in All India Counselling. These seats are filled through State Counselling. And there are 3 Categories in Private Dental Colleges. Category A is the Government Quota Seats. And only candidates of the home State are eligible to apply for these seats. With a score of 303, a seat here is difficult. B Category seats are also called Management Quota Seats and they are filled through State Counselling and the remaining seats are filled through direct Admissions by contacting the College directly provided the Candidate has registered for the respective State Counselling and has not been able to secure a seat in the Counselling. This is where you do have a chance.  Here the fees is usually nothing less than 40 lakhs. For seat in Private Colleges of Other States you have to appear for State Counselling of States like Tamilnadu, Haryana, HP, Karnataka, Telangana etc for a seat in BDS. And if your criteria remains no donation, then you have to reappear for NEET 2021 because with a score of 303, it is difficult for a Government Quota seat. The last Category is NRI seats Category and you cannot apply for that.
