The seats in private medical institutions are alloted based on the NEET score. The same is applicable to NEET PG also. Earlier anyone who even didn't give an NEET attempt are eligible for Management quota admission. According to the new norms for any kind of admission in a medical institution one needs to qualify NEET. A percentage of seats in a private medical institution are alloted for candidates who cleared NEET and have obtained a seat directly through the counseling. The fee structure of this candidates is decided by the government and is considerably very less. These seats are known as private seats. There are some other percentage of seats alloted for those candidates who didn't acquire a seat in private quota. These students need to apply for the Management quota of seats where the fee regulation is quite high when compared to private quota. There are some other seats which are alloted by the private board of members of those particular medical institutions. These students need to pay a high amount of fee when compared to private quota students which is almost 3-4 times higher than the normal fee. Candidates of these two cases fall under management quota. However for any quota one needs to qualify NEET or else he/she cannot acquire a seat in any medical institution.
