Hello student. Both of these two give exposure to the branch you wish to pursue. But there are thin lines of difference between these two. B.A in animationand vfx deals with only arts subjects till the end and is a bit easier. whereas B.Sc in animation and vfx deals with science and also few of the arts subjects and also a bit tougher. But bsc has brighter future and more opportunities. So if you are willing to put in much of hardwork, go for bsc
