Hello Prasanna, 

As per the previous year cutoff trends, and considering you are from the general category, there seems to be a slight chance of you getting admission in Rajiv Gandhi Institute of Medical Sciences since that had the lowest cutoff score of 493 in 2018 under the 85% State Quota. The other cutoffs ranged from 570 to 509. Wait patiently for the cutoffs and keep a lookout for other colleges as well to keep your options open. 

All the Best!
