Pure vent here. The end of the term was Friday, and final grades are due tomorrow. I brought some grading home with me, and as I'm watching X-Files and putting in some math scores, I realize that the big math test I did last week, already graded and passed back... has a total of 4 student scores when I swear up and down I entered every single grade. Gah. There's no way I can recover that data without giving the test again. Sigh. And it was big information, too.
