Hello Praveen,

Considering you are from the unreserved category, and as per the previous year cutoff trends, there is a very slim to no chance that you will get admission in any college with that score. The lowest cutoff last year for MCA was 64 in the open category in VSB Engineering College, affiliated to Anna University. 

However, don't lose hope, wait for the cutoffs, but meanwhile look for other colleges as well to keep your options open.

All the Best!
