Hi guys, I currently am in a position where I am able to ask my Neuroscience TA for a letter of rec. She told me that she is currently a PhD candidate. I am wondering if this would be looked down upon by the adcoms. Would it be weaker than one from a professor? If so, how much weaker? I currently already have 3 letters of rec (1 ochem proff, 1 dentist, 1 bio research proff) so I am not in a position where I really need to scrounge up some more LORs but I figured it would help.
