On one hand, customers appreciate the thorough coverage of topics, noting that the explanations and solutions are clear and detailed. This depth is beneficial for a comprehensive understanding of the material, especially for those preparing for the PE exam. However, the feedback highlights significant concerns regarding the nature of the problems presented in the book. While the rigor of the problems might be seen as beneficial for deep learning, many users feel that they are excessively complicated compared to typical exam questions. Reviewers have noted that some problems take an impractical amount of time—10 to 15 minutes—compared to the required 6 minutes per question in real exam scenarios. This discrepancy has led to frustration among users who found the problem-solving process tedious and not reflective of the actual test environment. Moreover, some reviewers pointed out issues with the wording of the problems and the accuracy of the solutions provided, which include incorrect assumptions and inConsistencies when referring to important reference materials, like psychometric charts and steam tables. This lack of clarity can contribute to confusion and diminish the overall effectiveness of the study guide. Overall, while this book is seen as a solid resource in terms of content, it likely falls short for those seeking a more aligned and practical practice tool for their exam preparation. ### Pros and Cons **
