First of all, Amazon, you should have an option for ZERO stars...I bought this book along with the Arco and Cliffs Notes study guides, and I would have to say that it is unique. I have never seen an "educational" book with so many errors. If I would have purchased any other book with so many errors, I could have easily returned it. Barron's has not returned any of my many e-mails explaining the numerous errors that are not ven listed on the "Book Corrections" section of their web site.Please do not buy this book. You will save yourself a lot of time by purchasing a good, reliable study guide. Don't pay this much for kindling...
