Thank you Madison for facilitating a great conversation about the new PE exam format, and also thank you for sharing your experience.
I also had a similar experience in that I took the Water Resources PE Exam and it was also computer-based. The major impact that the new format had on me was on my way of studying really. I was preparing for taking the exam on previous years, and I was using the textbooks I used at school, and some additional web resources, I was building a binder with a summary of equations and concepts. However, when the new format was in place, I changed my studying habit. I began by familiarizing the provided handbook. Fortunately, the company that I work also had the Civil Engineering Reference Manual (CERM) and used that for practice problems. Probably, the only resources where I spent money for the PE were on additional practice problem booklets (from NCEES and other websites) and the Water Resources codes/standards/resources.
