I also help on the grading, which always drives me bonkers. I was told today, "The students said the test was easy...so grade strictly!" They mean it, too. At one point a teacher asked me whether she should take off one point or two for a student who said "I have pain in my stomach" rather than "I have a pain in my stomach." (It didn't sound worth taking off anything to me, since I can't imagine it ever making a difference in real life whether that "a" is in there or not.) They are really serious about trying to keep the average score low so it won't seem they're being too easy on the students.
I also worked more on my next sewing project, which is melf42's present. So far it's coming along quite nicely. I hope the rest of it goes as well as the part I got done today.
