Query: Not like the other Arco books

I bought this book ... when I received word from my dad that GM was taking referals for Industrial Mechanics and he turned my name in. I needed to quickly brush up on my mathematical and mechanical skills before taking the pre-employment exam. This book really let me down.First - It didn't cover anything about how to do any of the shop mathematics until after you (the reader) had taken the practice exams. NO formulas, equations, NOTHING! And they DID explain it at the end of the exams, but not well enough to understand where you the reader screwed up.Second - There were so many errors I lost count and closed the book never to read it again. Several of their answers were wrong; there were many typos and miscalculations. I don't buy a preparation guide for errors all it will do is confuse you as to if you are correct or forgot how to do arithmetic. I checked several of their calculations with a TI-90 calculator and the answers I received were not the same as theirs. ...
