I would have to say for the inexpensive price and the fact that it encompasses almost all of the subjects, it is very usable. It teaches children computer skills, it sharpens their academic skills, and it keeps them engaged. My son thought that he was playing. I gave it a 4 because it is a secular site and there aren't any bible games on it. My son who used it is 7. We stopped simply because I went on a very strict budget.

Me and some of my siblings used this for math and a little for other subjects. My younger siblings loved theirs; it was very animated and fun. But as for me and my older sister, it was boring and confusing. Only a few of the lessons were animated. And it would't ork at times. I don't reccomend this for grade for and up, but for below that, I think it's great!
