If I am applying to multiple specialties and I have done a few extracurriculars specific to a specialty, then should I mention that in my ERAS application or my personal statement? I don't want either specialty to look at my CV and think "well, do you want to do this or that?" Say for example, if I did a peds observership and then cardiology research for a few months. Should I mention them in my PS for each specialty or actually put them down on my CV.
