Nothing wrong with the seller or the shipping, it's just the material in the book itself. I spent at least 30 minutes confused over this problem in the book that they supposedly "solved." Some part of the calculations were major typo, and it threw me off big time. Luckily my prof. uploaded some of the chapters on pdf and I was able to get the un-typo version of it. Just be careful when reading some problems and see if their work make sense, if not it's probably a typo. I don't know why this happen for the international version, but just a heads up
Fast delivery, book exactly as described, saved $70 by buying it here, I will defenitly buy from this seller in the futur, the book serves its purpos .
this is way cheaper than buying it at the bookstore... and is the exact same thing it has everything you need for class... so buy this book if you need it
