hi,

see To take admission in MD or MS course, you need to appear in neet pg exam, neet pg 2021 eligibility criteria is as follows:

Aspirants must complete an MBBS degree/provisional Pass Certificate which is recognized by the Indian Medical Council.

applicant must hold  a permanent/ provisional registration certificate of MBBS qualification issued by the Medical Council of India or State Medical Council.

applicant  must have completed the duration of their internship on or before March 31, 2021

****There is no maximum age limit to apply for neet pg , since you have already  in on going course of MD you should have all the eligibility criteria. now see in government or some of the private  institute post graduate students work as resident doctor and get monthly stipend. however I understand that since you have taken admission in private seat fees is quite high. however if you quite now you have to again repeat the full three years again and it would be counted as gap of year in your career. so some how if you can arrange the money , it would save your time. generally loans can be taken from bank as educational purpose.  however since there is no age limit you may appear in neet pg again. so the decision should be yours.

hope it would help.
