CQE Complete Test Prep Study Guide: Practice Questions and Answers to help you pass the Certified Quality Engineer Certification Exam on your first Try

Now that I passed my CQE exam, I feel qualified to comment on which prep materials worked and which did not. This book has questions that are good practice, however, there are fewer questions than the exam (160) and there aren't any explanations, so I ended up using other materials that have more information.
