I don't know about other products, what I do know is the Math Destroyer is on target for the DAT and will take you through a wide range of problems needed to succeed in this section. You do not want to be surprised on test day. At the least do 1-3, 7 and the last 3..but again that is at the very least if you are pressed for time. But if you have the book I am baffled as why you will not complete it! I do hope you change your mind and give the Math Destroyer a workout..
