This PE practice exam book is older but so helpful. The book has three practice exams with 100 questions each so it’s a great resource to keep testing/timing yourself. I found these questions to be more challenging than the new open book resources so they reflected the problem solving you may need to do on the actual exam. I found the conceptual questions in here very relevant as well.
Buy with ease, and expect a great experience from beginning to end. loc: 4-E / 2717.
Condition Notes: Book has little sign of wear or use.
PPI PE Environmental practice problem book. This book has each section of the PE exam broken down with 5-40 problems per subject. This book is the best to self study with because you can cover all the problems you need with multiple versions of the question and how they would ask it. I am selling my self study bundle as a set with the approved calculator on my account as well. I passed on my first try using the PPI books.
