My school doesn't have an IM Sub-I.
I applied for 3 away Sub-Is for the same time period, got rejecterino'd from all of them. I sent in the apps like 3 weeks ago, so I think I did so too late.
Well, our school does require us to get 4 weeks of "Procedure"-based experience, and counts EM towards this requirement. That's one reason I haven't dropped it yet, because its just easier to keep it and complete the credit.
The other reason is that the rotation is literally 30 minutes from my house, so its not like I have to spend money to stay somewhere for 4 weeks.
I know some people who planned for both IM & EM because they decided right before ERAS
however, while their transcript showed EM subIs they did get at least one IM subI in before ERAS
and while they didn't get a subI letter, and even had an EM letter, they had excellent IM letters
so I don't think the harm comes from having EM on there, it's more if you don't have IM subI or GOOD IM letters
if you don't have an IM subI, it might hurt the invites you would get
(luckily IM is a core clerkship so you've had exposure - I hope you did really well)
you could minimizing how much that hurts you by addressing the change of heart in your PS, and in general you need to address why IM anyway
as far as why your app looks the way it does and how you feel about EM vs IM, it will sort of depend on all your particulars of your app the best way to talk about this in your PS
and try to get an IM subI or even ICU subI before ERAS
line up some IM subIs before rank lists go in so you can mention that in your interviews maybe if all else fails
TLDR
you don't get faulted for having had some interest in EM, the IM/EM decision split is more common than you think
that itself doesn't concern PDs as much - it would be a perceived lack of interest/commitment in IM that would hurt you
you need to turn around your schedule to show via transcript, write a convincing PS, good solid IM letters, spin your activities
try to get that EM --> IM subI, if you can't, you can still apply IM but need to be convincing in your statement
