This series combines curriculum software from a variety of developers. The quality of each is uneven—especially Middle School (five discs), which has an outstanding collection of math exercises but also includes a Spanish lesson so crammed with information that the print is almost illegible on-screen. Math & Science (four discs), for grades 3 to 6, is the better of the two, with outstanding interactive math exercises in multiplication and division, fractions, decimals, and percentages, as well as astronomy games and weather experiments.
