When I went into the gradebook to go over princess's grades, I noticed that there was a number that shouldn't be there. The reported grade was the same that I'd posted, but there was an in-process number that was different...and was EXACTLY the number she'd need to get a 65. So our theory is that somebody changed that number so that, after this year's over, they could go look at the records and say, "Oh, whoops, this is the number that it should be, must be a clerical error, we'll fix that." That way they can hide the fact that they changed grades.
