Well luckily you're going for Surgery where a daily note with physical exam, etc. is not as emphasized (esp. something like murmurs). IM is a completely different story, I think bc they bill differently.
The most ironic thing in the first 2 years is that the main emphasis is on basic science, while the Physical Diagnosis course is like this thing that is there that you do, but it's not emphasized as much so it's like something you study less bc you have other obligations. It would be great if it was all taught after basic sciences is over, but then medical school would be even longer than it already is. And it's not like any medical student will actually read Bates' Guide to Physical Examination and History-Taking from cover to cover. I think the biggest habit for students is not to accidentally "lie" on their clinical note - like documenting CTAB on lung sounds, when it's actually rales, etc.
But yes if you are able to ask interns/residents/attendings that you are hearing things or doing things right on physical that always helps.
