It is difficult to predict a rank because the Counselling authorities for both MBBS and B.V.Sc are different. And a separate merit list is prepared for Candidates who want to apply for Veterinary Courses. But in 2019, under All India Quota, 537 marks secured a seat in B.V.Sc in Telangana. Well this is not a cut off but just an information to show how many marks you might need. You haven't mentioned your Category, the State you belong to and the College that you want to take admission in. But in general, for a seat in a Government College, you will need 550 for a seat in Government College under All India Counselling. Now cut offs change every year. Cut offs change every year depending on various factors such as no.of Candidates appearing for the exam, no.of Candidates qualified, top NEET score and difficulty of the exam.
