I'm pretty disappointed because this is not what I expected. Certainly there the whole program in a single CD-ROM, but it stops there. The working method is absolutely not fun! Already the children spend their days in class, so with this support, it is identical to the class. There is no adventure, nothing that encourages the child to work on. To help children in difficulty at school (which was the purpose in my case) is inadequate. This is great for parents who want the raw program with nothing around.
