Student A: my quiz didn't work right. I changed one answer I knew was wrong and got the same score.
Me: no, you gave the same answer the second time around...
Student X: I have no discussion grades.
Me: Clearly, you missed my multiple announcements about one of the discussions -- you'll get a grade eventually. As for the rest, you failed to meet the deadline EVERY FRIGGING WEEK!
grrr. I'll be happy to be done with them.
