There's a void between the categories authors/publishers are allowed to select for their work, and the categories readers can browse. They don't always match up, so to get into those extra categories, you need to use keywords. Look in the help section (there's a link on the first page of these forums) to see what might work to get you into that category.
Quizzes are nothing but trivia, and your book is listed in the Trivia sub-sub-genre. However, who knows, maybe you can get Amazon to add a new sub-sub-sub-genre for you, then add another beyond that as "Pubs." It would obviously help your ranking immeasurably. Go for it.
