Query: Do not get this book!

I am currently a student and am using this book to try and learn something about dynamics. The sample problems are great and easy to follow, BUT the rest of the questions i have found to be nothing like the sample problems, and are solved in a different manner. Many of my other fellow students agree, and as our lecturer is not very good i have to now RESORT TO BYING ANOTHER BOOK, very dissapointed and [$] out of pocket. Thanks alot Meriam
