Wow, DrH -- rabble rouse much? You're on a roll today ...
marieg -- My ds has the same issue -- his calculations are very, very good for his age (or for adults, for that matter) but he makes careless mistakes when rushing. I'd work with the process with your dd.
Also ... if she's going into 6th grade for lack of challenge, I see that 74% as a good thing -- she'll have some room to grow and might have to work a bit to catch up. That's good for kids who haven't experienced much school challenge -- better earlier than later. Having to struggle to learn *something* really is a gift to these kids, who learn really bad study habits if they aren't encouraged to struggle. Not struggle *hard* -- just enough to realize that working hard isn't a bad thing.
OTOH, if those scores preclude her from participating in all the other advanced classes ... I'd probably wait the year and continue with subject acceleration. But that's me.
