You don't get penalized per se but your score will be lower as they're counted as wrong. As its adaptive...finish the test, the last few ?'s dont affect score too much. And if you're running out of time on the GRE, I don't recommened taking the GMAT without some decent prep on whatever section(s) on the GRE you couldn't finish. Having taken both, the GMAT is a more difficult (though neither was markedly difficult) exam, takes longer, and has a analytical writing section (don't know when you took your GRE pre/post Oct-02).
Good luck to you. Finish the test, and if the questions start getting really easy, you're farking up, maybe look into cancelling scores and retaking. Peace.
