I requested a LOR from a professor in early April. she said she would write it (she knows me decently well) and that the way she normally does letters is to meet one-on-one with students right at the end of school to chat, and then she writes them while their meeting is fresh in her mind. Well, I've been emailing her for the last two weeks (I think I emailed twice so far) and haven't gotten a response yet. School just ended this past week, and now I'm panicking a little. I'm thinking she might just be busy with final grades and stuff, so that's why she hasn't been responding. but I really need closure on this because since she committed to it already, I've been counting on it and now I wouldn't have the opportunity to ask any other professors (since school is over). I'm thinking of emailing one more time, and if I dont get a response, I was thinking of just going to her office on campus. Would this be a bad idea? Would it be inappropriate? Like I said, she knows me decently well and I got the highest grade in her class (out of 300 students), but I didn't want to do anything inappropriate.
