Great info, inky, thank you! DH and I suspect he bombed the test intentionally, but haven't yet discussed it with him or his teacher. DS is just starting to learn about giftedness, and his initial assessment is "giftedness only makes my life harder."

The cherry picking described in your link is a strong possibility too. DS has developed an "easy or impossible" dichotomy when it comes to work - his resistance to anything requiring effort is getting stronger. frown
