I used this book to prepare for a ACT Compass Geometry test, to fulfill a graduation requirement. I am a 28 yr old returning student, and I'd been away from math in general for about 10 years. This was a great book for learning and reviewing the geometry concepts. I went through it quickly, in about 3-4 weeks. I just took the compass test and scored a 99 out of 100! Very nice. My one complaint is that there are a few random editing errors in the book. This definitely caused me some confusion as to why my answer was off, or how to do a problem. I've read the same complaint for other math books in their series. I am onto Algebra I next. Hopefully, I will be as succesful with that book as this one. Overall, a very good book.
