I got a 97. What I suggest is to study the dental decks until your eyes bleed. These basically incorporate all of the old test stuff. You need to go through each card very thoroughly, really paying attention to all of the stuff on the back of the card, not just the answer that they give. Then, I went through each section and determined the things that were difficult for me or not covered very well and tried to augment with other sources. Don't go too overboard studying things that aren't in the dental decks, just augment what you have in there. If you memorize the dental decks, you should get above 90.
