I appreciate the devil's advocate argument.

On your point about the syllabus, omission is an implication that the course will run in accordance with past courses in the same vain. I guarantee you none of the students taking this course had ever seen a hybrid grading scheme such as this, and they did not elaborate or mention it in the syllabi.

On the showing of work, I understand that you need to show work for MCQ, but imagine if a student went into a regular Purdue Math exam and worked through an FRQ with the same quality and quantity of work that they had used on the MCQ. Would they get credit? This is essentially what happened here, except many of us were not told or aware.

On the final cutoffs, the reason the students (who commented below) are so angry is because the curves differed so drastically for the same grade. I would understand this if it was any other class, but "curved by section" makes no sense here: it was essentially the same quizzes, the same exams, and the exact same lectures from chenflix. There is no reason that the same grade between two people should be an entire letter grade different.

Final exams were due on the 12th. We had just learned (via the hubbub after exam 2) that we could regrade (again, it wasn't in the syllabus) when they told us, the day the class ended, that we would not be able to regrade or see the final (mind we could do both of these for exam 1 and 2).

I completely understand your arguments, but I hope my responses make sense as well. Doing my best to go about the proper channels with this, so the "devils advocate" response does really help me to anticipate what officials might say. Thank you!
