Title: College Students Need the INTRODUCTORY Version, NOT COMPREHENSIVE Version!
Review: If you are looking to buy this for a college class, BE VERY CAREFUL because there is a confusing difference between the COMPREHENSIVE version and the INTRODUCTORY version.The INTRODUCTORY version has a secret password packaged on the back cover, so that college students must enter that password code online to get at the assignments, and the INTRODUCTORY version is under 400 pages.The COMPREHENSIVE version is over 700 pages, and it does NOT include the secret password code, but has a completely different CD that is not part of class assignments.
