in the Introduction section it says: "All the questions in the book are provided [sic], including the assessment test .... " which I think was supposed to say "All the answers to questions in this book are provided, ..." because it refers to the review quizzes, which do have answers provided.
The answers to the assessment test are also not in the online resources that I can tell.
Kinda useless to have assessment test with no answers.
Oops! Nevermind. They follow the assessment text immediately. They are not in the back like the others.
However, there are several typos in the book that need to be fixed. See the errata page:
