Since I homeschool and do not have to require my son to take any tests while a student I believe it is important to give him the opportunity to experiment with samples of what testing is like in order to prepare him for any future testing which may come up with in his education experience out side our own. This book has many positive qualities that can assist with testing comprehension: filling in answers like that on a public school test and many questions formated as state tests would by offering multiple choice. Although most of the questions are manageable I found some to be a bit confusing for myself as well as my son. This is a new format for us which may be part of the reason for any unsure perception of the material. I would recommend taking a look at the prep book before purchase to ensure this style is right for you and your child.
