As per the cut off of bvp cet law BA LLB 3 years , that is 180 , and you rank is 340, so may be you will not get seat in bvp llb 3 years. as your rank is higher tha the cut off. as i am considering you  as the general category candidate because you have not mentioned anything regarding your category. adn the chances are less of getting admission in bvp for 3 years llb, but you may get admission on the basis of mangement qouta. you can grant 100% seat over there through this qouta. in case if you may not get seat on merit basis. I hope this information helps you. all the best have a great future ahead.
