I am BCA student. i am interested in animation and Vfx so please tell me which course suitable for me?

You can connect with the institute mentioned below they will be able to guide you better: > School of Media Design > Arena > MAAC > Frameboxx > DSK others

As already you have invested lot of time in study up to BCA , you can join a 1 year diploma course which should give good exposure about 3D animation pipeline and some specialization.
