<p>So I've volunteered under a professor for almost a year so he knows me very well and I'm currently taking a class with him so I have almost a month of class work under him by the time he sends it in. Could I have him be one of my LORs?</p>
<p>If you're only other option is to send a mediocre LOR (or not send one altogether), then, yeah, I would ask him to write one for you. Won't hurt.</p>
<p>Yeah it's pretty much my only option. Most of my classes have been huge and the one's that weren't were taught by TAs. So hopefully they will accept it.</p>
