One of my daughters has an econ professor from Mongolia. The students can not understand the woman. Several students just quit coming. Most are failing; my daughter, who's an honors student, has a D.
I told her that the students would have to take group action to be taken seriously so they emailed the dean individually plus some went to see him. The upshot is that they will be given a major take-home test and then a take-home final. Thank the Lord, because her scholarship requires that she keep a 3.0 every semester.
