Okay so the description of what I what I had to do was:
essay 3000 to 3,500 words on some aspect of music education. This needs to show evidence of research and/or original thinking.
My assessor now wants a bibliography (which was not mentioned ever) showing which other research documents I have read (which was also not mentioned)and discuss these.
I realise that the whole of mumsnet is probably thinking "silly girl - fancy not knowing you needed that", but this has genuinely taken me by surprise as I have flown through the other elements and courses using the same layout and style. I got a distinction for my paper from the college of education, which was worth the same number of points as this one.
This close to Christmas and the end of term I just want to throw in the towel really.
