I have a 6th grader in the CA public school system and she's doing this math now in the first trimester of school, so I think this app is scaled inaccurately. And the questions are only addition, subtraction, multiplication, and division. I was expecting more variety. Knocked off one star for being too easy. Knocked off the second star for being limited in scope: no geometry, algebra, percentages, word problems, or vocabulary questions.
