Maybe a combo of both. She really does work slowly but she's also rather meticulous and she was coming off a really bad school year when she was IQ tested. Her teacher the year prior had spent a lot of time yelling at her, calling her lazy, and keeping her in at recess. We wound up homeschooling for the end part of the year b/c she was falling apart.
She really, really wants to do Duke's Marine Lab and has qualifying scores, but we can't afford it. She applied for the JCK Young Scholars program hoping they might help with things like that but she got a reject in the mail on Monday. I suspect that our assets and income were what ruled her out since we were at the upper end of the range they normally consider, we own our home, and dh has a reasonable retirement account. We're not destitute, but we're also not well off enough to pay $3500 plus travel expenses to send her to programs like that without pulling $ out of dh's retirement to do it which doesn't seem like a wise idea.
