This test prep is good for kids who are on the fence and having trouble passing, or need to increase their margin. These kids will often say "I DON'T KNOW WHERE TO START" when explaining their confusion.This book address that problem with three approaches.1) In contrast with the other study guides that use random questions in their practice exams; this book collated the questions into chapters based on the logic to solve them. The 8th grade book is divided into nine chapters. They are Logic, Arithmetic, Geometry, Fractions, Reading Graphs and tables, Measurements including a ruler, basic statistics, order of operations, and Algebra.This book teaches basics then goes into practice exams with word problems. Once the student is proficient with the questions organized into chapters then they are ready for random questions.2) This study guide has thousands of practice problems. I have placed over 3100 videos on YouTube showing you how to work the problems3) I reviewed several years of past exams and placed enfaces on the easiest and most common questions. Mastering these questions should yield a 75% to 80%. If a student is already achieving this percentage; the other guides or web site with random questions and covering all material might be best.A book might be better for your student than the web sites for two reasons. 1) The more common and easiest questions are using a ruler to measure. The web designers don't know the size of your computer screen and can't determine if the student has measured correctly. We can get a high percentage of these problems easily.2) When studying on a computer there are too many websites with the answers. With a book; parents can have greater assurance the work is being done. This book is developed by a trained professional out of concern. It is not the product of a large publishing house. It is the results of one person who wants to help.Best RegardsMark Shannon
