I used this book for a college intro to economics class. It has a lot of information for someone who doesn't know a lot about economics and the economy...maybe too much.
I found myself pushing to get through chapters because they were boring and many of the diagrams were confusing. Some of the concepts aren't very clear.
The CD that came with mine was a huge help. I would print off the study guides before I read the chapter, so I would pay the most attention to those parts because those are the ones the author thought were important.
This book had a lot of econ math in it that I was unable to understand. The CD didn't address that very well. Consequently, those are the questions that I missed on the tests.
