McGraw-Hill Education GRE 2018 Cross-Platform Prep Course 4th Edition

My wife borrowed this book from the library. Some of the answers to the math questions were just flat out wrong. This guide clearly wasn't checked properly when published, and that's a shame as the book goes into good detail then makes you feel like an idiot. Stay away from this one.

This book has so. many. errors. in it. At one point, 5-2=2 and at another 25+25+100=250. It must be new math. Additionally, there are multiple instances where part of a problem will be found to be one number, but then when it's put back in the equation the book uses a slightly different number throwing the overall answer off. It's full of issues. Until MH fixes it, use something else.
