I'm not exactly sure on how the exam is scored, but I don't think that having two research questions means you did better or worse than the rest. I don't know if one of the research questions was a "test" question that they may not use in scoring, or if having two research questions means that it will be harder to differentiate yourself from the other people that had two research simulations b/c the research ones are fairly easy.

We'll have to wait for the scores to come out to know more. I'll post mine here when I receive it in a couple of weeks.

Good luck!
