This book's review section is helpful; however, the explainations to the answers of the practice tests are not detailed. I'm still not sure how to solve some of the problems on the math tests. Other people I questioned had the same problem, which leads me to believe that, maybe, there are editorial errors in this edition. Overall, for me, using this book is beneficial, but has been in some instances frustrating. If you can get past the fact that you may never know how they arrived at some of the answers, you'll be fine, otherwise move on to another study guide.

I found at least one typographical, mathematical, or grammatical error in each of the three practice exams in this book. Once I discovered the editors had not proofread their own product, I lost confidence in it. I did, however, find that the book helped reacquaint me with the format of the exams.

I found this a useful study guide for the PRAXIS I PPST exams, especially when used with the ETS guide. The ETS sample exams are more authentic and seem better written. A good strategy is to study and practice with this ARCO guide, and then, when you are ready, take the practice exams in the ETS guide.
