Seriously, wtf?

So, I happened to check my transcript online just now because I couldn't remember a class I had taken a few years ago and I was talking about something with my roommate. I figured I'd look to see if, off chance, I had any marks for this semester yet.

And I had one. For the class that I just handed the paper in today at four.

I can only assume it's a mistake--either that or my prof is assuming that I was going to write some amazingly good paper and just gave me a mark without seeing the final product. Which somehow seems wrong.

Not that I'm complaining, because it's a good mark.
