I am going to prepare my independent study book, Invisible Man, Oedipus and Tin Drum for the AP exam. Invisible man is good for a question about self-discovery, symbolism, the power of language, and racism. Oepidus would be good since it deals with fate and free will. It also has a complex character with a complex flaw. And the tin Drum has powerful symbolism, existentialist threads, identity issues and questions personal responsibility.
