With an 80k rank in NEET PG under the OBC category and Maharashtra state quota, securing a DNB (Diplomate of National Board) seat might be challenging, but not impossible. DNB seats are generally less competitive than MD/MS seats, but they still require a good rank, especially in high-demand specialties.

Here's what you can consider:

1. Specialty Choice : Your chances improve significantly if you're open to less sought-after specialties like Family Medicine, Pathology, or Anesthesia, rather than high-demand ones like Radiology, Dermatology, or Orthopedics.

2. Location Flexibility : Being flexible about the location can also improve your chances. DNB seats in smaller cities or less popular hospitals may have fewer applicants, increasing your likelihood of admission.

3. Rounds of Counseling : Keep an eye on all the counseling rounds, including the mop-up and stray vacancy rounds. Often, seats remain vacant in these rounds, and candidates with higher ranks have a chance.

4. Private Institutions : Consider applying to private institutions if you're open to them. They may have seats available, though the cost may be higher.

In summary, while your rank might limit your options, being flexible with your specialty and location could increase your chances of securing a DNB seat.
