""While the problems in this book are very challenging, they provide excellent depth of exposure to the topics required on the WRE PE exam. I highly recommend this book since many of the problems go beyond just simple use of the formulas requiring understanding of topics that help to answer the tricky conceptual questions that show up on the PE exam.""

May Englert

""I have been using Dr. Petro's book for my PE WRE exam preparation, and I can't recommend it enough! The material is thorough, easy to understand, and extremely helpful in navigating the complexities of the exam. What really sets this book apart is Dr. Petro's exceptional level of support—when I reached out with a question, he responded promptly and addressed my confusion right away. At under 100 dollars, this book provides great value, and I honestly feel it is a better option than many other expensive courses out there. I previously took a class with PPI, and unfortunately, my questions were never answered. With Dr. Petro’s book, I feel supported and confident in my preparation. Overall, this book has been an invaluable resource in my exam preparation. I truly appreciate the effort Dr. Petro has put into making this such an effective tool. Highly recommend it to anyone preparing for the PE WRE exam!""

""This book was a real eye opener for me, it offered valuable insights and practical tools that I applied during my studies. It helped me identify and target my weak areas, which turned out to be more than I initially thought. As a result of that I deepened my knowledge of the normal topics and the new ones. I highly recommend this book especially considering the challenging problems it has. Per my own experience, the problems, or most of them are made intentionally challenging, but given the geotech is one of the most difficult topics and impossible exams, doing these porblems methodically will def help you prepare. Also, this book covers really all if not every code or topic or manual lists in the requirements!""
