Query: This book sucked!

I can't even begin to describe how awful this book was! I used Zumdahl first semester and was forced to buy a copy of Fay/McMurry for the second semester. I actually took the course with Professor Fay and I have never used a worse Chemistry textbook. Even Brown and Lemay is better than this. The explainations are superficial, if correct at all! Do yourself a favor...buy Zumdahl instead of this textbook.
