Duke MSII here. Thought I would chime in since this is, I think, one of  the most misunderstood aspects of DukeMed when I chat with incoming  applicants (and when I was first starting out here as well). I could say  a lot, but I will try to be brief. Don't read this as an "excuse" for  our first year, but rather just some friendly advice to step outside the  box when thinking about med school, especially DukeMed.
First, about step 1 scores ... Moral of the story: Duke students do  phenomenally in residency match (and that is made public). That's what  step 1 really matters for anyway. But to dispell your fears about  scores: Duke students have huge flexibility as to when they can take the  exam Third Year, and thus how much they'd like to prepare is their own  choice. Add the fact that since Duke students already have a clinical  year under their belts (which includes 3 elective periods to "try out"  specialties/subspecialties), they have a much clearer idea of what they  may like to go into. I personally know many who score 240/250, because  they choose to make studying for this one standardized test a priority  (making you competitive for  Ophto, Ortho, Derm, Radiology, etc). Yet I know others who did not make  such a high priority of a top score, because they are choosing Family  Med, Pediatrics, Internal Medicine, etc. Thus, even if the Step 1 scores  were public, Duke's average would be naturally biased. But the moral of  the story ... first year prepares you to do very well on step 1, if you  choose to put in the study time again before you take it. And unlike  most other schools, you get to determine what that looks like (Need 6  dedicated weeks to cram? Need 8 months of gradual study? Have family  issues and need to postpone it? Done.)
Moving on ... yes, first year is a long, strenuous stretch of time  compared to other med schools' first years. But to be honest, no one  told me med school was going to be easy. If you've heard otherwise, then  you may want to reconsider the whole shebang! Regardless, don't fall  into the trap of thinking you "stop" learning material during your  clinical years. We only spend one year in lectures, yes, but that is  really just to prepare us enough to start learning medicine on the  wards. You may not retain it all, but you don't necessarily retain it  much better with 2 years either. I would argue that the best kind of  learning is when you are working with patients, where you can still  learn and read about things like physiology, pathophysiology,  pharmacology but equate them with actual patients (no written test,  however good, can achieve that). Actually, someone far more experienced  than me came up with such an idea:
"Medicine is learned by the  bedside and not in the classroom. Let not your conceptions of disease  come from words heard in the lecture room or read from the book. See,  and then reason and compare and control. But see first." (Sir William Osler aka legendary Doctor)
Also remember that when choosing a med school, you are choosing a 4-year  package.  Medicine is a life of learning, and I am happy to know that  my 4-year package includes early clinical time (and not just "exposure",  but being responsible for patients, taking histories, doing physicals,  forming differentials, making treatment plans, performing procedures) as  well as an entire dedicated year of research which I would be very  hard-pressed to find anywhere else until well into residency (for me, it  will be research in global health). Our 4th year is just like any other school's.
But if you take nothing away from all my rambling, know this: DukeMed's  community is as much a reason to come here as the curriculum. My class  is an amazing group of people--yes, in their accomplishments and  professional potential, but also in their humanity, humility, and  concern for each other. That question about the most humbling  experience? Yeah, that actually matters here. That same  community extends well into a multitude of professors, alumni,  administrators I've gotten to interact with (and even the Dean herself).  Sure, there's a few bad apples but in general, it's pretty awesome.
Basically, it boils down to this re first year: I worked real hard and there were some  strenuous times, but I was not nearly as miserable as I thought I would  be. In fact, I more often found myself thriving than struggling.
So much for brevity! Best of luck in your application and decisions, those who read this.  There are many places you can learn to be a great doctor, and DukeMed is  certainly among the best. And don't believe everything you read on SDN. It's a very select population with a very loud voice, and not necessarily representative of the whole. You already know that, but just a friendly reminder.
And I think Duke basketball is pretty good too. (Shameless plug.)
