I just finished taking my CLEP exam this morning an recieved a 65 when I needed a 50 to pass. The only study material I used was this book. I studied it for a week, and took all the practice exams and reviewed the anwswers with the explinations in the back. There where a few questions on internet marketing on the test, but most of it was common sense. One question on the test was this "How do marketing companies rate the success of banner ads on websites" and out of the five answers they provided one was the most obvious "click-throughput" the rest where just stupid responses like "the banners size and color". Using a text book for this CLEP is over kill, and it might hinder your success, because this book sticks to the facts and the must know material. I highly recommend this book for the Marketing CLEP, if you only study this book like I have you still have a easy chance at passing this exam. Good luck :)
