Query: umm... not so sure about this one

To be honest, I used probably less than half this book. I read through the verbal sections and those were ok. I skipped much of the math tutorials because I use math all the time in school. But when I got to scale reading, 3 out of 10 of the samples questions had incorrect answers. That was a shocker to me. How do book editors let 3 errors go unnoticed. Following that, in the mechanical section, there's a statement about how you compare viscosities of liquids."engine oil has a high viscosity because it flows easily while molasses has a low viscosity because it flows quite slowly."For those of us who've had a decent amount of exposure to either math, science, or mechanics, we would know this is a complete fallacy. The typist probably got "high" and "low" mixed up late at night while drinking liters of coffee. But this does a huge disservice to anyone who isn't too familiar with these things.I give this book 2 stars based on the absurdity of the errors.
