Congrats to DD on the scores. In previous years from the Duke talent search, a 500 was about the 80% for reading and for math.

As for the conflict, I did a frantic combination of events when I was younger and had sports/school conflicts with academic award ceremonies or opportunities. It seemed to be a good compromise, albeit a less-than-ideal one. For me, some of the conflicts with school or my select teams were worth the drop in grade for the chance to meet age-peers who were also intellectual peers...
