Query: CAVEAT EMPTOR...

I purchased this PE Exam Preparation package to supplement my study, using the MERM as the primary study guide. I must agree with the other reviews. After reviewing the first chapter, I found the following issues:1) Simple proof reading errors that should have been caught, both in the examples and chapter problems.2) Inconsistent answer solution detail - some are very detailed (great), while others choose to skip some steps.For example: Chapter 8 - Fuels and Combustion, has virtually no structure in the solutions to the examples. It is almost as if the author is verbally explaining the solution, and a person is writing it down as they go.I hope the 8th Edition has addressed these issues, but I personally do not want to evaluate. In any event, one should NOT use this package as the sole resource. The MERM by M. Lindeburg, and MGI PE Readiness program should be used first.
