My dd is also not a super fast child (slower than a wet week comes to mind regularly) but her coding score would still have been much higher had she been cooperative. She did exactly two of each item (perfectly), put down her pencil and then watched the clock for the second half of the available time. She scored 10, in half the time, with no errors... And the psychologist saw nothing odd or problematic about this. I would not have even known if I hadn't been there...
