Hello Raghul, 

Considering you're talking about your chances in MBA, and as per the previous year cutoff trends, the cutoff score for an SC category candidate in University departments of Anna University, CEG was 51. Since cutoffs change every year and your score is just on the borderline, you seem to have slight chances of getting admission. However, keep a lookout for other colleges as well to keep your options open. 

All the Best!
