Accuracy of GMATPrep

[hobble]

I just completed Practice Test 2 of the latest download of the GMATPrep software, and scored 690. Does anyone know whether the scores from this Practice Test would be reflective of what I'd get for the actual thing?

Based on all the info I have read in the past several weeks the consensus seems to be that the gmatprep tests are the most accurate representation of the test because it uses retired questions from past gmats. I have read some people say it is more difficult and some say it is slightly easier so I guess take it with a grain of salt. More importantly I would use the info to try to find your weaknesses come "g" day becuase in the end it only matters what that score says, but I understand the desire to have a gauge of where you are in te process. Im taking my first gmatprep tomorrow morning after taking 6 mgmat simulated tests so I will probably post something on that experience tomorrow afternoon. Oh and most people will probably mention the "real" gmat has a std deviation of plus/minus 29 pts and that is both true and disquieting due to the relative importance that schools place on the test.

Yes, the official test has a standard deviation of 29. They do not publish the St Dev of GMATPrep but it has to be higher for various reasons (e.g., the pool of questions used is smaller, some of the questions used have already been published in OG, etc.). So, while GMATPrep is the most accurate of the practice tests... none of the tests (including the official test) are as accurate as most people think they are / would like them to be.
