Assuming that one practices under realistic test conditions, then multiple scores of 700 with any practice test should probably be seen as a good sign. With that said, Princeton products are more suitable as a refresher or for those whose target score is around 600. The questions are easier than those found on Manhattan or Kaplan
tests, and the scoring algorithm is a bit off.
I strongly advise you to use the GMATPrep software to have a better idea of where you stand.
