OHST Certification Exam Review Questions and Answers 2016/17 Edition: 60 Unofficial Review Questions covering the Occupational Health and Safety Technologist exam Large Print Edition

This is the worst study material I have seen. The 60 questions do not cover all of the domains and skill sets required on the OHST examination. There are no mathematical problems presented or discussed in this "study guide". And of the sixty questions in the book, many of them are repeats of earlier questions. I have taken the BCSP 100 question practice exam and this study guide doesn't come close to presenting the same material at the appropriate level of complexity. What is the value of a study guide that offers no references from the Safety Body of Knowledge in the explanation for each question? This reads more like someone trying to make a buck by selling a study quite then someone who is knowledgeable of the OHST examination trying to help others study. If I hadn't spilled coffee on it, I would have sent it back immediately.
