Very general rule of thumb:
BFA = 66 to 75% practicum (voice, dance, movement etc,) and 25 to 33% traditional academics
BA = 25-33% practicum and 66-75% traditional academics
I found this article on BA vs BFA helpful when my D was looking:

Have her visit schools, go to info sessions, and set up meetings with department heads and/or students. Get a feel for what she likes.
It’s definitely possible to apply to both BA and BFA, but if you can decide early on a path it can sure help simplify the application process IMO…
