Hello all, so I am doing my best not to panic. Today is my deadline for my graduate school applications (and is also a holiday, Martin Luther King Day). I have one letter still outstanding, so I emailed my professor to remind him. He just emailed back to let me know he has gone out of town, and will not be able to submit until tomorrow morning. Is this going to be detrimental to my application? There is not a grace period for reference letters, or so the admissions website says. Thanks in advance.
