GMAT Prep software

Hi . I have taken the GMAT prep tests( Downloaded from mba.com ) .
Some 2 questions were directly from the OG in the verbal section .
Can one trust that he would get the same score or nearly the same on the GMAT from the prep scores ?

Can someone clarify ?

if you remembered those answers your score may have been slightly inflated...you can rest assured that you will not see any repeat questions from the OG guides during the real GMAT exam.

The questions repeated were from the verbal section .
The questions in the Math section were all diff.
So can i relate my Prep score to original score ?
I mean how reliable an indicator is the GMAT prep regarding final scores ?

there is nothing more reliable than gmatprep i guess...
