Query: dissapointing...

I have bought Math Advantage 2002 and that was an excellent software package by Encore Education. But the Elementary Advantage 2002 is the biggest disappointment. The grammar, spelling, reading sections teach nothing but are annoying games that do nothing to explain wrong/right answers. I wanted my niece to learn about grammar, spelling, etc., but there are no tutoring sessions or explanations. Very disappointing... considering the price.
