OP
I used to have a ppt presentation I used with adult students who were often disappointed with results. I'm supply so I wasn't there at the start of the course but I often got stuck with marking and picking up the pieces when someone had left.
The first slide gives an assignment of, "draw a cat".
The second slide has two pictures, one is a crude drawing of a cat made with MS 'paint' the other picture was the Mona Lisa.
Then I would ask which was the better picture?
Which would get higher marks?
This leads to a discussion of doing what the assignment says. The Mona Lisa isn't a drawing and doesn't feature a cat so in this context it does not march the assignment and doesn't get a score. On its own it is a wonderful example of Da Vinci's work, but that's not the marking criteria.
I then had other slides with a drawing of lots of cats (you don't get any more marks for drawing more than one), a photograph of a cat (it's not a drawing so scores zero).
This is what your dd has to remember, she has worked hard but somehow she has not fulfilled the criteria for a distinction. It does not reflect on her work ethic or abilities.
This is an opportunity to learn, to discuss with tutors what could have raised the mark, what did she do that did not get credit because it was irrelevant.
Hopefully she has some feedback alsong side her grade.
