DO NOT PURCHASE THIS BOOK.
Format: Paperback, Format: Paperback
If I could give zero stars, I would. Do not purchase if you intend to use the Access Code. I was very careful to scratch off the Access code, but you can see it was still unreadable. I went to the website and submitted a ticket. One option for a reason to submit a ticket is 'unreadable access code", so they know this is a problem. They ask for a photo of the code and a receipt of purchase. I sent both. Then they asked for proof that the book was purchased NEW. This was not noted on the Amazon invoice. I was instructed to reach out to the vendor for the additional info. Or I could spend more money on another access code. There are other study options available.
