Government quota means the number of seats that are decided by the government for the college. If u wish to get a seat via government quota you may have to write Cet exams (for engineering) and get a good score. The cost of seats is comparatively very less compared to management quota seats which are provided by the college. For instance government quota seats for medical cost like 55k per year and no donations. While management quota seats may need a donation of 70lakhs to 1 crore or more. And even the yearly fees is 4 times the fee u pay for government seats.
