I only have good things to say about the RFU BMS program! I am a bit biased because I got into CMS, but from what I saw, most people who had Bs or higher and performed decently at the interview got in. I was really worried about RFU only looking at my BMS grades and the interview, but if I got in with my sub 3.0 cGPA/sGPA and many red flags on my account (won't go into specifics), I truly believe that this program is the blank slate type program that you want.
Doing decently on the interview is quite subjective though since we aren't very good judges of our performances, but you can do lots of mock interviews with the advisers and former BMS students now in CMS to get a good gauge of how you are doing! The schedule is changing up next year so I can't comment on that, but I feel like RFU really focuses on the BMS kids and tries to get them into CMS so I would think this trend would continue. The main RFU allopathic 2017-2018 thread talks about how no one has been getting acceptances for a while, but the BMS kids have been getting acceptances throughout that time period so this means that RFU places a huge emphasis on getting BMS kids in the program. Furthermore, I know some friends who had Cs in classes currently in progress and got acceptances after initially being on hold. Of course we have conditional acceptances where you need to have a B or higher in all your classes so getting a C in the end won't do you any good.
I can answer some questions about the program if anyone wants to know more, but I'm sure the new BMS program is still having its details worked out. Feel free to PM/reply to this message. Just be aware that if you come to RFU, you will most likely be going to CMS if you do well in the program and interview. Make sure you are okay with that.
