A=98.2%-100%

B=91.9%-98.04%

C=85.7%-91.8%

D=79.5%-85.5%

F=0%-79.3%

This is not an error or a typo on the syllabus; it's the intended grading system. I'm not worried about passing the class, but this scale seems extremely odd and almost arbitrary. With the exception of an F, shouldn't the ranges be consistent? Only a 1.8% range for an A while a 6% range for a B, a C, or a D? A number of students and I approached the professor over the grading system but the professor insisted that the system was to encourage students to work harder. But how much control do professors have in defining their grade ranges? What if an economics professor wanted to make the lowest C you could get a 93% to "encourage students to work harder"? In principle, this is exactly the same as the above grading system. Are professors allowed to freely manipulate the grade ranges as they please? It seems ludicrous to me that an 85.0% grade in this class--what would be a solid B--gets bumped down two letter grades to a D and thus resulting in your failure to pass the class because of an arbitrary grading system.
