Hello dear

All 3 colleges you mentioned is good for BBA hons course

But comparatively, Scottish church is the top college in kolkata for bba hons

Even when it comes to placements Scottish church provides better placement for bba hons course.

And then Asutosh is also good college and also provides good placements

And shri shikshayatan college is good for bba regular course

Hope its helpful!

Good luck !
