Hey guys, So my cousin is going to dental school and she wants to work as a dental assistant to gain experiences. She's asked around and most of the dentists only take those who are certified. So we're trying to register for the exam. Also, we were wondering if she has to take any required course in order to take the test, or she can just buy the book to self study and then go take it? If so, is there any books that you can recommend? Thank you very much !
