I started my prep (self-study) for the GMAT about a month ago and took the 2 GMAT prep tests for practice a couple of times. I was surprised to see that most questions were not repeated when I repeated the tests. I am now wondering if there are many interesting questions buried in the test and may not surface unless I run the tests multiple times - this of course is quite time consuming! So I am curious whether people have compiled an exhaustive list of questions from the software and this compilation may be available. Any pointers would be of great help. (My search did not yield useful results).

BTW, this forum is extremely educational and informative. Thanks!
