Myself Dr.mahesh I did my MBBS from b.m patil medical college, karnataka. What rank I have to get in neet pg so that I can get seat MDdermat

If you want to get a seat in to MD dermatology after having past year MBBS from Karnataka you will need to think about the priority of state in which you want to pursue it census data Karnataka has a death of government medical colleges and you might have to require a very good rank within the top 1000 in order to get a Dermatology MD seat in the government medical colleges of Karnataka but however if you are willing to try for other states with your all India rank as well then from the 50% quota of seats availability as per the all India rank and Kota you can avail Dermatology CSVTU all India rank of 2500 to 3000 and DNB Dermatology can be accessed with even lower ranks of upto 5000 to 6000 all India rank
However since streams like radiology and dermatology the premier choices of toppers you must team for a rank of within 1000 for which you will definitely have to get score in excess of 850 out of 1200 in the Neet pg examination
