personally, I would say it ranges. anywhere from an 11.2 to 12.3. It's hard to say though. Sometimes you feel real good and you're like "Yeah, I'm AWESOME. I have so much dental knowledge right now." Then, you have a downer day and you're like "MAN! Where did all these skills go??" But overall, I would say I have an abundant amount of dental knowledge.
Seriously though, I think its pretty safe to say that we are all at a 0. Relatively speaking.
