I would say all medical schools (MD and DO) are based towards "primary care" as when you learn things in your first 1-2 years, it's general broad topics and same goes for 3-4th year, you learn to manage your patients in given rotations. Years 1-2 prepare you for Step 1, so the curriculum is pretty much standard across all medical schools. Each school may have better or worse teachers in some subjects, but in the end, their goal is to prepare you for step 1, so it's pretty much the same everywhere.
On a surgery rotation they don't expect you to know how to take ou the gall bladder, but you have to understand pre/post-op as well as the anatomy, presentation, and clinical significance of the gall bladder.
When you interact with SP your first 2 years, all the cases are patients that would present in a clinic or doctors office.
