Title: Received wrong book
Review: Ordered 8th edition and received 7th edition. Seller said he was a calculus teacher and that there was little difference, so I agreed to keep it. Turns out the teacher my daughter is taking calculus from said that it was not helpful, as the tests were based off the odd number problems, and the odd number problems were not all the right ones. I had already agreed to keep this book with a $10 credit before I found this out, so I ended up buying a new study guide at the bookstore for $50. What a waste.
