This book is only good for computer test, it has small computer shots with one question and answers on each page, so although it has lots of pages, they are quite waisted on useless computer shots/pictures that you can view on CD prep. This book does not prepare you for the paper based exam, because it doesn't present the reader with enough printed exersises.
