I was really excited to go through this book and test my Harry Potter knowledge but it is a big disappointment. Of the 165 questions, numbers 1-53 are about the meaning of terms used in the books, like alchemy, and some creatures, like banshee. At that point it only moves on to asking questions about the origin of some of the words and then goes into the origins of character names (through question 66). For the following few questions it asks about different British dialects. Next it describes how to answer the essay posed in Azkaban " Witch Burning in the Fourteenth Century was Completely Pointless. Discuss." After that comes a section with trivia questions about J.K. Rowling, with several questions about her name, what her net-worth was circa 2007 and creepily intrusive things like the name and nationality of her first husband and what animal she is allergic to. Starting around the 100 questions there are some really easy questions about the movies (who plays Harry? who plays Ron?), some really obscure (box office take of the first 5 films), questions about shooting locations and now out of date questions about where the theme park "will be." Starting around question 125 the questions get into things that J.K. Rowling has said in interviews such as inspirations for character names. The next to last section is issues, such as how different churches feel about the books. Lastly is "lessons" to take from the book, basically asking about the moral implications of the book.
Overall, this is not a quiz book so much as it's a trivia book (and yes, there is a difference). There is not a single ounce of plot line trivia in this book. If you're looking for a true quiz book, try The Book of Harry Potter Trifles, Trivias, and Particularities.
