See..as per previous years..you would rewuired a percentile mire then the 40th percentile.. meaning your marks should be more than 40 out if 100 students sitting fir tge exam or atleast 40% of the marks  attained  by the topper..this might turn out to be somewhere around 358 out of 720..
However fir a govt Medical College..i would say aim fir a 370-380 will be good enough for a college by sc rank
However,this again would depend whether you're opting for the colllege via state rank or aiq rank..
However, whatever it be..try for a score above 370..preferably above 380 ro keep your choices open to all govt colleges via state or aiq quota...
Yes for a good govt colg..a sc score of 400+ is desirable..
