As you have asked for Stanley medical colleges. So you have pretty decent probability that you will grab a seat here through 85% tamilnadu state quota seat. Last year cutoff for obc for this college was 562 marks (391 state rank). so if we take 30-40 marks cutt off rise this year then also you have pretty decent chance of grabbing a seat here.
