Registered Dental Assistant?
I have my EFDA %26amp; My RDA and lets just say in college I had really good grades and I think it was harder then the x-ray exam. You'll for sure want to study your *** off. Get any kind of book that they are recommending for your state I'm in Pa and I took mine a good while ago but I can remember thinking thank god I studied so much. I hope you went to school for assisting. Good luck.
Reply:I defiantly agree. When I was in school nothing they said had anything to do with the test. But the books really helped and I passed my first round.
