DS8 took it today. It was his first ever standardized test that wasn't given by me, I think.
The bad news: he finished less than half of the items on the test to hear him tell it, though he did allow time to guess at the end of each section, so at least there are (hopefully!) no blanks. But I don't hold out much hope for a fab score.
On the bright side, he said, "Every one I answered, I know I got right." It was a good experience and he enjoyed it. So that's all good.

If only he were faster... *Sigh*
