First of all CONGRATULATIONS to your daughter! I will speak to the USC end of things. My daughter is a USC School of Dramatic Arts BA with an Acting Emphasis.
Both the BA and the BFA programs are difficult to get into in this school. Some very talented acting students will choose a BA because they may choose to go on for an MFA or they want a more well-rounded education in addition to their theatre training. My daughter has taken information that she has learned in her GE classes and applied it to her work in her theatre classes. So there are super talented BFA and BA actors at the school
BFA students have a designated progression of classes. BA students have requirements but have flexibility in choosing other acting classes. Students may take up to 18 units per semester so there are plenty of acting classes that a BA student can add in. So that gap of 25 units you computed could actually be smaller when you consider that. If you want to chart out things look on the BA requirement list for School of Dramatic Arts. Once you speak to a counselor to see what credits transfer and what your daughter needs in the way of GE classes then you can chart out what she needs to graduate. You can check the Schedule of Classes under School of Dramatic Arts to see what classes are offered. Classes like On Camera Performance, Voice-Over, Acting for Commercials, Shakespeare, Comedy of Manners, Musical Theatre Audition, Stage make-up, Dialects, Improv, Sketch Comedy are usually offered as well as many more. Contact a counselor in SDA if you have any questions.
There are plenty of acting opportunities. The department puts on several productions a semester. Some are BA only, some are BFA only and some are open to both. There are productions that are open to anyone on campus as well. USC also has several groups that are managed and run by students. They put on ISP’s (Independent Student Productions) every semester. The first week of school all clubs and organizations will set up tables and your daughter can visit all the theatre groups and sign up. Look into Musical Theatre Repertory for musical theatre and Aeneid Theatre Company for straight plays. My daughter has done shows with both groups. There are probably others as well and maybe someone else can chime in with information about them. The School of Dramatic Arts (SDA) sends out a memo a couple weeks before school begins called something like The Great Audition Memo. It gives information about all auditions for the semester. Sign up sheets for auditions are available on the bulletin boards in the hallway of the SDA office.
USC has a top-notch film school. Film students are always looking for actors! As I recall, in the beginning of the year, there us usually an email sent to acting students to come audition at the film school. There is also word-of-mouth recommendations. My daughter was recommended to someone who got in contact with her to act in her 2-person, 6 minute film. Someone else asked her because they knew her. Those things happen as well.
BA students can work professionally. I do not believe the BFA students are allowed to do this.
The BA students and BFA students all know one another. They are in some classes with one another, in shows with one another, go to parties with one another.
Over the course of two years my daughter has been in 5 musicals, two straight plays and been asked to be in two film projects. She loves musical theatre so she leans toward that but the opportunities are there for straight shows, musicals and film acting opportunities.
My daughter has a teacher that is directing a play this summer in LA. He let her sit in on audition day so she could see what it was like from the other side. Her MT audition teacher brought in Christine Ebersole to sub and my daughter sang for her, another teacher got free tickets to see the David Mamet play with Rebecca Pigeon and Felicity Huffman, SDA sometimes has some low priced LA theatre tickets, students see SDA shows for $5. There is also the Visions and Voices program which brings in directors, dancers, poets, musicians, you name it. You can probably see their offerings with an internet search.
Sorry, I got carried away here but as you can see there is a lot available!!!
