Barnard Opportunity Program

Hi, I’m applying for Barnard RD and it’s my absolute dream school! Due to my economic situation, I decided against applying ED. This was before I learned about the Barnard Opportunity Program. I was wondering if anyone that has been admitted through it (or that knows someone who has) could share their perspective? I asked admissions to share stats of how many people are usually admitted through BOP, but they just said a “small amount.” If you have any knowledge about the BOP please share!! I have an interview with an alumni tomorrow, should I bring it up? Also, should I email the admissions counselor of my region about my interest in the program now or after the RD deadline? Thanks!!
