to provide exposure to the different fields of medicine or specialties to hopefully give the student the best exposure possible of what they want to do in their career and the other is to get into them into the best residency program possible. So it's residency selection and acceptance.
The question is whether BYU will be able to provide that exposure without a direct university-based hospital system (I think so for the most part with IHC) with the main question then becoming being how will residency programs/directors view BYU applicants.
BYU students will likely test well regardless of the curriculum. So the main question is whether there will be any bias against them. Probably not, unless if BYU's School of Medicine makes the news for controversial things. The other question will be whether residency directors respect the non-academic IHC affiliation.
>99% of what contributes to a physician's training and competence is determined by internship/residency/fellowship and learning on the job. Med school contributes nearly nothing to that (in my opinion and experience).
