hi,

see since you have already completed the mbbs course and mandatory Internship, I assume you are asking about neet pg exam. the eligibility criteria for neet pg exam is as follows,

There is no age limit for the candidates  to appear for NEET PG 2020.

Candidate must possess an MBBS degree from a recognised Institute.

He/she must have completed one-year compulsory internship.

He/she must have a provisional/ permanent MCI registration.

so you may try again to neet pg if you want to give another attempt.

hope it would help.
