<p>I would definitely suggest talking to her in person about figuring out some way to make up the grade. Come with a few possibilities, but don’t barage her with all of them.</p>
<p>I’ve had a friend mess up the scheduling for his finals twice, and both times the professors let him just take it at the next time that worked for both of them. Naturally, the rest of us thought that seemed a bit unfair, since that wasn’t an issue of him not getting up so much as an issue of him not being prudent enough to actually make sure he knew when his tests were.</p>
<p>That said, I have slept through an alarm and missed half of a final (although I immediately got dressed and got to class and asked if I could take the test then, being completely honest about why I was so late to begin with - and wound up finishing it before some of the students who were there since the beginning), and so I can totally feel your pain, which is naturally made worse because you know that it was, at least in some capacity, your fault.</p>
<p>Face to face has to be the way to do it. As has been said, this leads to the personal connection that you (hopefully) have with your professor. Also, it makes reasoning and reaching some deal easier, as there don’t need to be a series of proposals back and forth, and you can read your professor better.</p>
<p>Best of luck!</p>
