My faculty advisor is teaching me a class this semester and I am hoping to get the 3rd letter from him. I'm not a very active student and most professors don't remember me. Well if he's my faculty advisor, at least he knows me. Less importantly, he's famous in the subfield I'm applying to, although I don't know if it matters at all if he doesn't know me that well.
My problem is that, I feel way too awkward to ask him. I've been talking with him about grad school applications and who to write my letter for a while, and he's been telling me all those stuff about how to choose schools and ask for letters, how to write the SoP, how to prepare for gre etc etc. Now I feel super uncomfortable and embarrassed to go to him and be like "hey actually could YOU write me a letter."
I don't know whether I'm just being too shy. I'm also not sure if I'll do well in his class or not. What do you think?
