Anecdotally, which is the only observations we have, the repetition of Biomed content in the MD due to its broad base and core subjects seems to make Biomed better preparation. I mean, everyone finds it hard but I don't think you can completely discount the above.
You're right, one cannot discount it outright, but I certainly question the tangibility of the as yet unproven advantage and to what degree it should factor into the decision of an aspiring med/dent student choosing between biomed & sci. Personally, as a DDS student and in my frequent association with the MD students, I'm not convinced it confers any significant advantage. Maybe slight familiarity in the very early stages, but little more.
Admittedly it's problematic to make generalisations either way, as different students tend to get different things out of the same degrees.
Anecdotally, the overwhelming consensus of people who are in graduate medical and dental degrees is that the disciplines or curricula of prior degree make virtually zero difference overall. A cursory glance at forums such as PagingDr would convince most of that. Also, it appears very little biomed content is actually repeated in either MD or DDS - rather, its not repeated in a way that those from biomed are at a distinct advantage to anyone else - as the medical science taught is done so in a completely different context, degree of detail and manner.
What we do see and hear is that those who did better on the prerequisite subjects and recall the anat/phys/biochem content upon starting find the first 3-6months slightly to moderately less stressful than those who did poorer or are less confident in those areas. After that, it's virtually a level playing field whether you're a Bachelor of Music grad or Biomed grad.
it may offer a slight help with medicine in the future as it will be focused eg. on human systems, and this 'help' may not be content per se but it's more of the past sort of thing, that you're more used to dealing with it.
Yeah, that's a fair assumption. I'd say that seems to be the case for many biomed students in the first 3-6 months of the MD course, but the advantage this basic familiarity confers after this seems to be minimal.
Personally I'd do biomed if I was completely and utterly uninterested in anything other than what is offered in the biomed degree and if flexibility of in major/minor/elective choice was not something I cared about.
