When applying to psychiatry residency programs, does it matter if I submit 4 letters of recommendation instead of the standard number of 3? Also, does it matter much who the non-psychiatrist letter writers are? I have letters written by two psychiatrists, two internists, one family physician and one surgeon. I'm including both psychiatrists with every submission, but I'm curious if it matters whether I include certain specialties from the others, and if I should just pick one or two. Thanks.
