She quite possibly has attention issues. Her handwriting is fine, but small, and as I said, she has this weird compulsion (I use that word intentionally) to fit everything on one page and not use extra paper. She still does things in her head that she should not do in her head. I notice that there isn't an obvious pattern as to what she gets wrong on tests--it's not like she just gets the hard ones wrong. She frequently increases a somewhat mediocre test score by getting extra credit points (her teacher puts brain teaser/logic questions on the tests for extra credit--she always does these!)

Let's see if I can add some more background. Without sounding braggy, DD is generally good at everything. Because she has always expressed resistance to/lack of interest in math, we have set it aside as "not her thing." I suspect that if she weren't all-around high ability, we would have paid more attention to the sparks in this area that flash from time to time. It's of interest that her standardized test scores in math are always higher than in reading (not that those are not high, but math scores are always 99%). She may just score higher on math SAT than verbal. But she thinks of herself as a writer and artist. BTW, though, she loves Vi Hart.
