I've heard and read that, but have never found actual studies documenting it. I'd be fascinated if she gave any more information about that.

Congratulations on your child scoring so well! I think it makes sense that that is extremely valuable in being able to accomplish what one sets out to accomplish. I'm going to look into that for my son, but I know he won't get comparable scores... learning about strengths and weaknesses can be very helpful, though, and I think it would be useful.
