Review title: Very disappointed
Product review: I bought this book hoping that it covers the topics in the GRE CS exam. Found out that the first 4 chapters are just general talk (chitchat) and does not explain/review the concepts in the exam. The sample test is very poor and I believe some of the questions were answered incorrectly. I am returning the book because it does not worth a penny! It is sad that I am losing shipping fees.
