Hello there, aspirant.

The required cutoff score for college admission is determined by the number of applicants, the number of seats available, and your category.

Because Tamilnadu has only about seven veterinary institutions, the number of seats available is limited. There appears to be more rivalry for veterinary seats this year, especially because candidates who did not acquire MBBS seats have switched to BVSc. So, based on previous year's trends, the minimum qualifying threshold for you as a general category candidate would be about 191-192. College-specific cutoffs may vary, however for state quota seats, a score of 350 or more is ideal, while for the 15% all-India quota seats, a score of 450-500 will suffice.
