Wowers! I was taking the ISEE test for 9th grade and I was really nervous. It was only a week before the test. We ordered this book right away and I studied and praticed it every night until the test. It taught me everything and gave me lots of pratice tests right away! This is a genius invention! I got a wonderful score on the test and I know it was because of this book! And you don't have to spend a year before studying! I recommend this book to any - it will really really really really ( I don't know how many times I should say this) really helps! ;-)
