While I LOVE the Key To Algebra and find it extremely useful, this Geometry program is strictly for children. It is angles, shapes, and degrees...not Geometry as needed for a high school education. It is extremely redundant and extremely simple. An average middle school student could do a book a day.

The constructions are fun and interesting. It is not a college-preparatory geometry course, though, because there are no proofs and no transformations (which are so trendy these days). Also, the early books especially move awfully slowly for a high school student. A 5th grader can handle the first 3 books or so, and you might enjoy spreading the series out over a number of years.
