If I could, I wouldn't buy this book. The reason it has so little value is that it doesn't have solutions for the problems anywhere. You could go through the workbook, but how would you know that you did the problems correctly?
I needed this workbook for my college physics class and the seller shipped it very quickly and it arrived in about 2 days,and that was across country from Virginia to California. The workbook came as described which was near perfect condition, and also came very quickly, which saved my ass in my physics class. Highly recommended, would buy from again.
