When you started this course, you should have been prompted to type your name in a text box to receive a personalized Certificate of Completion. If this DID NOT happen, reset the prompt for the certificate now by clicking on the last chapter in the left-hand margin (chapter 15), and then clicking through to the end of the course (until you see the blank "null" certificate). Close the course and restart it. You will then see the prompt for personalizing your certificate.
