It's very important to view EVERY slide including the REVIEW YOUR QUIZ SCORES slide in order to get your certificate. Don't forget to check out the resources on the resource tab (on the upper right corner of the course screen).
TIP: Did you know that you can zoom in (or out) on items on your screen by holding down the CTRL key and rolling your mouse scroll wheel forward (or back)? OR you can hold the CTRL Key and click the + sign to zoom in or the minus key (just left of the +) to zoom out.
