Depending on the evaluations she may be there next year, and the next and the next.
It may be unavoidable to have her as an instructor.
However, if she stays I would think things will change.
The Dean suggested I find a mentor in a 3rd or 4th year student........
It is a shame, but like one of my extremely empathetic classmates said,
"Well, somebody is understanding it because there are A's"
Gee, thanks chump!
