These days it's pretty much required that you shadow doctors as a pre-med, but is it like that in med school too? That is, do you HAVE to shadow a physician of your specialty of interest to match well? Or should I rather spend time doing research in the field? I am doing the latter at the moment and haven't shadowed anybody yet since I entered medical school. I can probably ask the doctor who I am doing research work for but is there any reason to, especially if you are pretty much set on one field already?
