<p>So I'll be applying for grad school in organic chemistry this fall and I still have no idea who to ask to write my third letter. Last summer, I worked at a government facility with 3 phd's on an analytical chemistry project which is pretty unrelated to what I want to study in grad school. I feel like I left a memorable impact by the end of that summer. They nominated me and I was chosen to present my project at the end-of-summer colloquium, representing the entire chem division. So of course, I asked the phd I spoke with the most to write me a letter. </p>
<p>My second letter will be coming from my research advisor at school who I've done research with for the past year and a half. </p>
<p>As for the third letter, I'm stumped..I took a graduate-level organic chemistry course last semester and got an A in it, so I was thinking about asking that professor to write me a letter. I only came to his office hours twice, and he doesn't know me that well so I'm afraid that the letter isn't going to be so great apart from "he got an A in a grad-level class". </p>
<p>Who should I choose to write my third letter? One of the two remaining phd's whose work is unrelated to what I'll be studying in grad school but could possibly write a more personal letter? or the professor whose grad-level class I got an A in but doesn't know me so well?</p>
