DD (5 next week grin) is a smart cookie. Maybe technically GT, maybe not, but people comment that she's super-sharp. I do think school will be easy for her and we're bracing for the possibility of it being underchallenging. (I see PS in general as underchallenging even for high average non GT kids because it's catered to the masses). The reason I don't think she is PG like DS6 is because DH and I have never had that panicky "what are we going to do with her in school eek" discussions that we had about DS at the age of 3.
