I have mixed feelings on that book as well. It does contain a lot of information in a fairly condensed format but I feel that EngPro Guide gives me more bang for my buck. It's been a while since I've looked at it but if I recall correctly I found the motor section in the Graffeo very helpful. I don't think i ever made it through the whole book though. I do remember working one of the theory examples and getting super frustrated. It was something I couldn't wrap my brain around at the time. I will definitely be going back through those examples.
I think on
@ItsStudyTime! website below a ToC was posted for that book that may be more useful than what it currently contains. Depends on the version you have though. A good job was done of sectioning that book off by NCEES topic.
Thanks for that by the way
@ItsStudyTime!
