I just failed a university-level course that the instructor assured me I was passing. We've discussed my grade in emails but we continue to disagree on how it should be calculated and even on what assignments should count. (The instructor did not adhere to the grading policy in her syllabus - this is a passing/fail issue.)
I have proof that I did enough to pass. Grades are in and the school is out for the holiday break, but I feel like I need to do something before this becomes permanent. What should I do? As a student, how do I challenge a grade I think is unfair if can't resolve it with my instructor?
