As someone in the MRSP program, I have found it to be a truly incredible experience. The research support is top notch, we are given freedom to pick our mentors and research projects, and have regular contact with pioneers in all fields of medicine. Further, as the previous poster alluded to, the administration has stated they do not really put much stock in using medical school as a proxy for competitiveness, and I believe our cohort of 43 students has something like 35 different medical, dental, and veterinary schools represented.
Feel free to PM me if you have any more specific questions about the program.
