BU CFA/CAS Dual Degree

Hi! I’m applying to college this year and BU is one of my top choices, particularly for their dual degree program. Most schools have told me that I can’t double major with an acting BFA but BU has been the one place that has said yes I can. I really love physics and want to be able to continue learning about it, which is why I love the dual degree option. However, today I got an email that said that the option is no longer available to freshmen, and that once you have been at the school for a year you can apply for the dual degree program. I was just wondering if there’s anyone who’s had experience with the dual degree program and what it’s like, whether it’s worth it, and also if it’s possible to complete the dual degree program in four years (I don’t really want to be at college for five years, especially given how expensive BU is). Thank you for your help!
