I was a student in a master's program this past year. As part of the master's program, I worked an externship during the last semester. The supervisor at the externship told me that I was doing well, but told my instructor I was doing poorly on an activity that was not detailed in the syllabus as part of the course activities. At no point did my instructor say that I was doing poorly, until it was time for my master's degree to be issued. Even then, no details were provided to explain the poor performance. To make a long story short, I feel that I have done what I am supposed to according to the syllabus. I have already initiated the grievance procedure at the university and they have ruled in favor of my instructor. What are the next steps?
