Update:
So she started crying at the end of class and blamed it on being emotional, said she was going to "re-grade" everything.
She was also the professor that was crying because Steve Jobs died......I'll let you design majors guess who it is.
The first econ course I had the teacher was horrible. It was in a big lecture hall, Dairy Industry 117 as I recall, and eventually everyone was talking among themselves while she went on up front, which she found very upsetting and eventually let us know. No one got anything out of the lectures and that is part of what they were talking about, the major reason people started talking. Today I can say it was like a Seinfeld episode or something.

We were pretty much all freshmen I believe and this was our second quarter (a long time ago) or more probably would have been skipping class already. I think the first test maybe about everyone got low Bs or middle Cs at best, all about the same, because we just didn't know the material, and as I recall the test was poorly designed like class. Or IMO she might even have made it extra hard to teach us a lesson, to show us how much she knew.
I wasn't the type to go out of my way to meet with professors, but I did in her office immediately after class once because I had to for some reason. It was obvious she had been crying, and she had to compose herself. Made me feel sorry for her. It just had to do with scheduling or something, but me stopping by she actually really appreciated.
Sometimes I think people have things going on in their personal lives, that aren't going to be resolved in a day or two. But I think she just wasn't a good teacher.
I believe she was just a graduate student. But for some of the comments here, it is hard to imagine she went on to a teaching career.
In fairness, my second econ teacher was outstanding and similarly a graduate student I believe, though she was probably as good of teacher as any professor I had. In a huge lecture hall she was also as hot as any of the women taking the class

not to in any way detract from her excellence as a teacher.
