一般prep摸考和真实差多少？

The tutorial, section instructions, exit screens, and Background Information
Question (BIQ) section are not timed in the GMATPrep™ software but will be timed
during the GMAT™ exam. You may want to spend extra time on these screens in the
GMATPrep™ software to familiarize yourself with them before you take the actual
test.

The optional break screens are not timed in the GMATPrep™ software but will
be timed when you sit for the exam. For the length of the optional breaks, refer
to www.mba.com. Keep in mind that, if you exceed the time allowed for one of the
optional breaks during the GMAT™ exam, the extra time will be deducted from the
time available to complete the next section of exam material (the Quantitative
or Verbal section).

In the GMATPrep™ software, you are permitted to move back and forth between
the screens in the preliminary sections of the practice exams (the Welcome
screen, the Nondisclosure Agreement, the school selection screen, and the
tutorial). In the GMAT™ exam, you will not be able to return to a previous
section once you have completed it.

During the practice tests in the GMATPrep™ software, you can select Show
Answer and Check Answer buttons to display answers and check your work once you
completed the practice test and reached the Review screen. In addition, the
GMATPrep™ software contains a Show Flag for Review feature that allows you to
mark questions you may want to return to later. These two buttons and the Flag
for Review feature are not available during the GMAT™ exam.

After completing a GMATPrep™ practice test, you will see scores for the
Quantitative and Verbal sections; however, the Analytical Writing Assessment is
not scored in the GMATPrep™ software.

Keep in mind that the GMATPrep™ practice tests are meant to illustrate GMAT™
content and are not accurate predictors of performance on the GMAT™.
