I purchased this eBook from Amazon because of the price savings. To my disappointment I found out that there was an additional component 'CourseMate' from the publisher, cengagebrain.com, that was needed to access the numerous media links and tools. There was no mention on Amazon's site regarding this missing component.
After accessing the eBook, the cengagebrain.com is referenced immediately and quite often, giving information about CourseMate. If purchased separately, which I would have had to do, CourseMate would have been an additional $100.00! I decided to go without. Information concerning CourseMate needed to have been disclosed by the publisher on the Amazon page.
Regarding the content and structure of the book, Sexuality Now: Embracing Diversity, 4th Edition, there is nothing out of the ordinary. Unfortunately, a textbook requirement is a requirement, and there is nothing a student can do to change that.
