Help with applying to Business of Cinematic Arts program! Urgent!

Hello,
I was admitted RD to USC Marshall Bschool for this fall (class of 2020). They sent me an email asking me if I want to apply to the BCA program. I looked into it and I really liked it but there is barely any information online. The application process involves 3 questions. Do u have any idea about how long each answer should be? Should I write 3 essays or just a few words for each question? Thanks! Any info about statistics of admission would also be helpful!
