I used PPI to study for the Civil: Structural PE exam in August of 2024. There were a lot of things I liked about using PPI, including the huge supply of practice problems, the ability to generate quizzes with custom lengths, and the ability to track my progress on answer times and knowledge areas. I also really appreciated that the PPI interface matched the NCEES one, so it felt really familiar when it came to writing the actual exam. My only criticism were that a handful of the practice problems had issues with the solutions (ie: where the text within the question didn't match the graphic provided, where values presented in the solution didn't correspond to the referenced design standards, etc.) It was nice that there was the ability to report this, but I feel like I came across more instances where I needed to report discrepancies than I would have expected.Still very happy overall: I passed the PE exam, and would recommend PPI to colleagues who take it in the future.
