I received a LoR from a professor I know wrote me two great letters in the past for different programs. His letter was the best I've gotten. However, it seems like he waited until the last minute for my med school letter as he just showed it to me today and it's relatively badly written with 1 or 2 glaring errors(including repeating a line at the end). English is his second language (he's German), so none of his writing would ever be called poetic, but there were a couple of things that just made me cringe. The problem is the letter is already submitted to AMCAS. What are my options at this point? I'm sure if I corrected the mistakes he would resubmit it, but how does AMCAS handle something like that? If I just have to deal with it, what is the worst-case scenario? How much emphasis would they put on one badly written letter out of four?
