I am short one letter and I have no clue what to do. My pre med committee requires 5 letters. I have 2 professors, 1MD, and my PI. That's only 4 :/. I have no other professors that I have established a relationship with or will probably even remember me. O have been babysitting since I started college, would it be okay to get one from one of my kids parents? Or would that be seen as weak or suspicious? Babysitting is the only job I've ever had.
