510 was the cutoff for Koraput Government Medical college in 2018 which was equivalent to a rank of AIQ 17948. As the cutoffs had increased this year due to increased number of candidates and also the paper level which was called easy comparatively, the cutoffs went around 528 this year. So to be on the safer side you need to score around 540+ to ensure a government medical seat. 

Best wishes. Thank-you.
