Query: Worst...Pchem book...ever

Just finished a 2 sem course in Pchem. Professor assigned this book, but never used it for his lectures, except to make the test questions. I think he purposely chose all of the questions that were worked out wrong, just to frustrate us. He didn't have to look hard to find erroneous questions, the chapters are full of them. The book offered no information to help understand the lectures. As I study for the ACS final, I find that none of the concepts ACS presents are covered in this book in a manner that is useful. I would venture that any P chem book on the market is better than this one. Heck, even Wikipedia is better at teaching Pchem than this waste of trees. If you are assigned this book for a class, (sorry) find another one (book or class).
