PPI Six-Minute Solutions for Civil PE Water Resources and Environmental Depth Exam Problems, 2nd Edition – Contains 100 Practice Problems for the NCEES PE Civil Water Resources and Environmental Exam Second Edition

Excellent book - has a good collection of practice problems for the PE exam.

I like the book, I bought it for PE exam.

Excellent book with questions just as advertised. I would have thought it might have more questions or longer explanations for $80.

This book is not worth the money. The book is titled six minute solutions but on average I would say I spent about 30 minutes per problem. There are also numerous wrong answers and solutions that make no sense how they came to that solution. It would have been useful if the author cited specific sections of the CERM so you would know where these equations they used came from. For $100 this is not worth the money. I'm taking the PE exam for the second time in October and I'm throwing this book in the trash. Do yourself a favor and spend $400 more dollars and do the EET prep course.

These questions are a lot harder than those found in the PE exam for water resources. This book is more challenging and will make the actual test seem a lot easier. While not awful, I was disappointed with the amount of time most of these questions take to answer.

Well it's a great book to learn more about water resources, but like everyone has stated, the problems are much harder than what you need for the actual PE.

These questions kick your butt. Great prep.

Worked great for passing PE.
