She has done games and programs on the computer, like IXL or Dreambox, and she does Raz Kids for school which does have some quizzes. But she has done them enough to know how to navigate them and how they're scored and when she must answer or when she can go back later and so on. I can only assume she gets one chance at each question on this test, no coming back?

I actually dislike these computerized tests for important sort of tests, because it's so much easier to not read closely on a computer screen and she can't use any of the strategies that really help her, like underlining the important words so she doesn't miss something.
