That's interesting, Dude; I hadn't heard that. DD's test notes, such as they are, say "DD gave up easily if she could not answer right away." In a certain mood, she can get very "Who cares/I don't know" if things are a little challenging. (This is especially true if she has to respond orally vs. a written answer--I'm not sure how the test was administered, but I assume it was oral.)
