Thanks. I'm not really back -- eighty hours a week, plus frequent travel for work, is incompatible with doing much more hereon than lurking. But I still exist -- the edge of the Earth hasn't presented itself yet.
To the OP: There've been lots of my own students there each time that I've taken it. It's not weird, really. My students seem to like it; we chat before and at breaks. They ask about how I'm going to do/am doing/have don, and seem to be comfortable talking about that, I assume as a substitute for dwelling in their own, understandable anxiety. They hassle me a bit about messing with their curve, but understand that it doesn't have any material effect. (On the other hand, this time it was different: I had the Robo-tuna passage, so I assumed my effective scoring pool might be substantially reduced; I therefore cancelled my Jan 27 score lest I push some of my own students' scores down.)
Before anyone asks, re retaking with the score I had: I've long said that I will apply if I attain a certain score; I was just shooting for it. And I'll stick to my promise. If Q had just taught me organic chemistry, back before I disappeared, maybe I'd have had a shot. Oh, well -- guess it's continued test prep for me.
