This company sells hundreds of these CLEP prep guides. I bought this one because I'm under great pressure to get credits out of the way. I spent weeks reading and memorizing from this book to prepare for the Geology clep exam and eventually caught wind of the fact that very little of the content is in the sample tests and very little of the sample tests contain questions for which the book prepares the reader. I called the College Board to ask if they sell or recommend anything better, where I was informed that THERE IS NO GEOLOGY CLEP TEST!!!
f I have money I;d take these people to court. I want my wasted time back!!
