Real GMAT comparable to GMATPrep/Official Guide?

[hmgp22]

For those of you who have take the GMAT already, are the questions very different from those in the Official Guide and GMATPrep? Was it a big surprise? Obviously, I'm not expecting an exact same replica of those questions with the numbers switched around, but are the questions at least somewhat "familiar?"

Unfortunately, I'm one of those test takers that get thrown off more easily than others when question types seem unfamiliar. I've covered all the Official Guide/GMAT Prep questions thoroughly and understand them in addition to MGMAT, but am worried that I'll walk into the exam completely surprised. Thanks.

GMAT Prep has the best representation at this point. The Official Guide is a good place to start your practice, though.

I just took it last week. I would say taking gmatprep and then studying all the questions from gmatprep after u are done with your studying is very beneficial. In fact, I would say I saw one or two questions from quant that were identical questions.
