Hello, 

As per your requirement, i would say that as you habe got a good rank of 2769 in neet mds and you are hoping a call letter from army dental cops, them definitely you would get there. 

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
