You're looking at the ADA sample exam. This is the same ADA that has their sample DAT exam ask if organisms that obtain teir energy from light are called autotrophs.
Here are some questions from previously released NBDE exams... from an era where many people didn't have the privledge of the internet, forums, and wiki as study sources:

d. Produces a less than optimal load.

Now take these questions, and add them to 494 more questions, and try to get 340 correct just to barely pass. Or just don't listen to me, the NBDE I and II are cakewalks. Buy one of the previously released exams and if you can get 50% of the questions correct since they're all so obivous, I will bow down to you since you havn't even entered dental school yet. I'm taking the NBDE I in the summer and the DAT is a joke compared to this.
