I have lots of hours of shadowing, but the problem is I shadowed my older brother, so I can't get a LOR from him. I also shadowed a few other doctors in his hospitals, but mostly I was with him. I don't think the other doctor's would write me a strong letter of recommendation so I don't want to ask any of them. The only LOR I have right now is my pre-med committee one which I know for a fact is very strong. I want to put the shadowing hours in my ECs because I have atleast 200+ hours of it, but would it look bad that I don't have a letter?
