Thanks guys. Platypus, everything you just said makes perfect sense (and sounds SO familiar!). I think my kiddo thrives on the 'thrill' of getting everything right on a test, so it is intrinsically motivating to do well on tests. I just wondered if he was more like me and the stress was helpful (its WAY easier for me to get stuff done if I have stress from a test or an approaching deadline), and if this was a 'not-likely-adhd' type marker.
