Dear Hemanth, as per the jee mains result in 2019 the cutoff for obc-Ncl is 78.2174869. As per your score, we can directly say unfortunately you are not qualified for jee advance. But you have other option too and do counselling of some other colleges which offers admission on the basis of jee and provide scholarship on the basis of your rank or percentile in jee.

best wishes dear
