A diminished 7th is not really a scale; more of a broken chord, in this case. You'll presumably also need to find out the range which is expected (how many octaves) but her teacher should be able to tell her all this information.
Thanks for this. I can find out the range from the syllabus. I thought it was a scale which is why I wasn't making progress.
