 Hello everybody and welcome. So this is what the new Quality Assurance Study Guide looks like. This is a full course for those dental hygienists who are taking your quality assurance exam. So you might notice on the CDHL website that they do tell you what to study, but you don't really know where to start depending on how long you've been in practice. You probably don't have any of your textbooks left, hopefully not. And you just don't know where to start getting all of this material from. So the good news is you guys don't need to buy anything additional other than this course. You don't need to buy any additional textbooks. I have everything that you need to know inside this course to pass the exam. I have used a series of textbooks. I have used a series of resources from the CDHL website, from the CDHA website. Mainly textbooks though, textbooks, which is pretty much where everything comes from. And if you guys notice you will see over to the left hand side here, some additional things for you to look at to know how to prepare for your quality assurance exam, you know how many questions, what types of questions that is all right here. So after you go right into it into the different topics that you have to know, there is a quiz after each one. So after you look through all of the material, you can then take a quiz to really see if you truly understand everything. So all of the topics that you have to know for the exam, nothing more and nothing less. As you guys can see a lot of infection control.
