Query: Too many mistakes to take more seriously.

There is simply too much fluff and too many errors for me to take this book seriously. I fell for a good review off another site of this book and while I admit it isn't generic and easy (Priceton Review) or long-winded and overly difficult (Kaplan), I found simple errors like another reviewer all over the place!I even e-mailed the editors about these errors, and they said they would correct them in the new edition, but it looks like I was wasting my time. They're simply not doing their jobs because I felt like I was reading a pre-proofread book. Horrendous.It's okay for review if you KNOW these concepts already, but if you are learning some new things, there is no way to tell what is correct and what is not. (If you know everything, play a game with how many mistakes you can find. Have fun.)Also: I did fine on the test. Over 700, but that is because I like chem a lot and am taking ap chem right now. While this book may have helped a bit, it was excruciating.
