text: This book does cover alot of information not needed for CLEP, but it does give you a great guideline on who and what to study for clep and good examples on what questions will look like for the actual clep.  
  I wanted to ensure I was prepared for the clep, so I purchased this book and disregarded the other 2 comments.  Although, they were right about the obscurity, this book still taught me alot.  
  You don't necessarily need it, but if you want to be prepared, this book will not hurt your bank account that much. I also recommend The Complete Itiots Guide to American Literature (5 stars, check out the reviews), and the Internet.  That is all you need
