If there were a way to give this negative stars I would.
If you are looking for an electronic babysitter with some educational value, this is the software for you. However, the interface is not intuitive; the voice-overs sound forced; the program is twitchy if you happen to "leave" the window during a demonstration or practice.
They advertise 3 or more program levels per subject. I have yet to find anything of the sort. The printable worksheets are only useful if you have a printer immediately handy. They do not appear on the screen ever that I have seen. They can _*only*_ be printed out.
It's rigid, restrictive and unforgiving.
