Q: When you buy this book (10th edition), do not buy the one with the CD-ROM. It is not the right one (it is the 9th). All the books with CD-ROM have the wrong one. The correct one comes out in October. So if you want to buy this book do NOT take the one with the CR-ROM, because you're going to waste money!!
A:
Negative
