I asked for a LOR at the beginning of May. Professor said he'd be happy to, met with me to talk about specifics, asked for a due date and I told him mid-June and he said no problem, and he even told me to let him know "when' I get in. He hadn't submitted it by the beginning of this month. I emailed him and he said he should be able to finish it within a week. I unfortunately didn't see his reponse to that email because it went to spam, but I found it 2 days ago, so about a week and a half after he said he'd have it done. I emailed him thanking him again, asked to have it done by next Friday or if he could give me a more reasonable date to have it finished, and he still hasn't responded to me. What do I do? I need this for one of my two science ltters. I took a July MCAT so I won't need this letter for maybe 3-4 weeks but I'd really like to have it ASAP because I"m worried that he won't do it. I don't know any of my other science professors well enough to ask. Do you think this professor changed his mind somehow even though he was very willing initially?
