Hello, 

As per your requirement, i would say that as mentioned above, neet pg vacant seat exavt no can't be told as it varies from state to state. 

Mop up seats exact calculation cant be done but you can get an idea from the official website.

Getting a seat in government medical college is depending on many factors like studenrs to seat ratio, cut off, reservation, ranking of college, etc

Cut off varies evert year as per your reservation category and no. Of students applying for the same. 

Or else, you can get admission with low cut off through management quota also.

Good luck
