Interesting, as I've been told that ADHD/ADD kids have the ability/desire to hyperfocus on things that interest them but not on what they consider boring, tedious work. In fact, it's been explained to me that it takes so much effort for them to focus that they don't want to make the effort unless they see the value to them (e.g., interesting, or there is other motivation). And when they realize that what they focused on was meaningless to them (e.g., work that's too easy or that they've already mastered) they can get very frustrated and upset.
