Thank you for your query!

~~~ GMAT: COMPREHENSIVE and GMAT: PREMIER are our main GMAT preparation guides.
--The COMPREHENSIVE Program provides details on all the GMAT sections, and proven strategies to tackle the GMAT question types, along with practice questions and detailed answer explanations. (For the Writing Sample, practice prompts and sample essays are provided.) It also comes with 2 full-length practice tests (1 in book, 1 online) and an online companion. The online companion includes a diagnostic test, additional practice writing prompts, and a study planner/progress report that helps you keep track of your scores and completed tasks.
--The PREMIER Program comes with everything in the Comprehensive Program PLUS it includes new practice quizzes every month (with registration of your online companion), as well as a CD with 4 additional full-length practice tests and more practice quizzes for each section of the test.

~~~ GMAT 800 is our "advanced" workbook, which contains samples and strategies for tackling only the most difficult/challenging questions you may come across on each section of the test (except for the writing section, which doesn’t contribute to your 200-800 score). The purpose of GMAT 800 is to give test takers that extra edge/advantage in order to get that perfect 800 score. It is for people who have already created a foundation of knowledge and strategies by working through either the COMPREHENSIVE Program OR PREMIER Program.


FYI: The Kaplan GMAT Premier Live Online Program (which releases in June 2009) has all the great features of the our original Premier Program, PLUS innovative new features, such as Fast Fact Videos (expert GMAT tutor reinforces the most important concept from each chapter in 5-minute videos) and Live Online Events (online session where you interact with an expert instructor and fellow students using video, audio, instant chat, whiteboard and screen-sharing functionality), as well as a Reference Index for the questions in GMAC's Official Guide to GMAT Review (11th & 12th editions).

Best of luck on your exam!

Sincerely,

Monica P. Lugo
