Becase as long as you pass, you pass, regardless of the exam version. @=)

And if you make a note on the Betas (or an exam) about a problem being wrong or the answers being wrong for the scenario, then Provantage forwards the information to Microsoft who re-evaluates the questions based on your notes. After the review, if you've made your case sufficiently in the attached notes, Microsoft or Provantage can choose to alter your grade upwards because you obviously understood the material and caught them with their pants down. @=)

Sometimes, like in a beta, this can make the difference between passing and failing. Though, I wouldn't advise people to try this tact just so they can "fix" their grade. You really have to know what you're talking about and provide excellent reasoning for this to work. And the question/answer setup has to be actually wrong and not just a trick question.
