Dear Tanu, there are 3 Categories in Private Medical Colleges. Category A is the Government Quota Seats. And only candidates of the home State are eligible to apply for these seats. B Category seats are also called Management Quota Seats and they are filled through Management Quita Counselling of the respective States and he left over seats which are transferred to the respective Colleges are filled in through direct Admissions by contacting the College directly. Here the fees is usually nothing less than 40 lakhs. The last Category is NRI seats Category and you cannot apply for that. The reason why Management Quota seats are costly  because they are the revenue generating seats for the College.
