Thanks. Marking me on if I have heard of a particular author, that could fall into the wrong criteria used. I have paid around 6K for this course and I don't really see it as fit for purpose.
I can assure you that will not be grounds to make a complaint to get the marks changed, at least not at my uni. That is academic judgement, it's basically their opinion - that marker thinks that you don't know this subject area well enough because you don't know that author.
The marking criteria could be "the student knows the background", a scale 1-5, the marker thinks 2/5 and makes a comment you didn't know that author. There may have been other things you didn't know as well, but they just didn't write it all down. It's not that they used the wrong criteria.
How can you argue it? "I know the background, the marker is wrong", marker says "no you don't, you missed out this and this", "but I knew this and this", "so what, you missed out this and it's really important".. You can't win. Think about it, it's like a case of who will they believe, the marker who for all you know has been studying this area for infinite years, or you, who's been studying it for one?
The wrong criteria would be that they assessed your work using a marking scheme meant for something else, or judged you at the level of a PhD student, not a MSc student, something like that.
