But I'm already into a college with first year about to end, any how thanks

Since your marks in Board exam is good but Anna University looks cut Off marks if your cut Off is higher than 170 and above then you will get good colleges through counseling. All the Best!!!!

Chances are less to get seat in good college as the score is not that sufficient. But yes, you can try for more number of colleges as all are having their own criteria and cut off and common counseling is not there.

Good Luck!!!
