USEFUL FOR BEGINNERS!
The Official Guide for GMAT Review, 11th Edition is very good for people who wuold like to start their preparation for the GMAT. You have enough exercices and and a useful section (explanations) about math, algebra and geometry.
After, if you need a more brilliant preparation you need to practice on GMAT 800.
I'm Italian and when I started to read GMAT 800 (by KEPLAN) I found it harder (contents and language).
so-so
I wasnt totally happy w/ The Official Guide for GMAT Review, 11th Edition. As other readers have posted there are countless errors in the math sections. For example on page 335 of the 11th edition they say (xr)^2 = x^(2r). This is hard to look over as a typo - as are other errors.
There are also no full-length exams in The Official Guide for GMAT Review, 11th Edition. I mean, come-on, why are the GMAC guys such tight-wads with their questions. I dont really like they way they run the show...
Good book but with some typo's
Math section has many typo's (more than 10 for sure), use google to find the corrections. Apart from that its good.
Great source for practice questions, but not good for theory review
The Official Guide for GMAT Review, 11th Edition should be the first one you buy during your GMAT prep as it contains retired GMAT questions from past exams - this gives you a much better feel for the types of questions you are likely to encounter on the day. There are plenty of questions to practice with in both the quant and verbal sections - although beware that if you are also purchasing the old exams from the [...] that some of these will be replicated.
The real weakness with The Official Guide for GMAT Review, 11th Edition is with the level of detail in reviews. Particularly in the maths section, it does assume a level of knowledge and some topics are not well covered at all (e.g. combinations, permutations). If, like me, you are someone who has not touched high-school maths in 10 years, then it ... Read More
No longer useful as it once was
GMAT has changed a lot over the last 3 years and the materials in The Official Guide for GMAT Review, 11th Edition are no longer as useful as they once was. Most of the questions in The Official Guide for GMAT Review, 11th Edition are over 10 years old and they share approximately 90% of the questions with the 10th edition.
The result is the difficulty level and types of questions contained in The Official Guide for GMAT Review, 11th Edition are no longer fully reflective of the questions one will receive in the real GMAT. If you need proof, download GMAT Prep (just google it) from the providers of the GMAT and you will see the GMAT Prep questions are substantially different and more difficult than the questions from these guides.
The 1400 questions contained in these guides, however, are still somewhat useful, particularly if you ... Read More
