On my site, Example 7.9 has a slide with all kinds of results (including
what the specific answers are to the questions). I know several people
have modified this to make a certificate of completion, so the only
information that needs to be changed on the slide is the name.

Actually, it could be pretty easy. If you have slide 22 as your
certificate, you could set it all up, and have a text box for the name.
If you name the text box something like TheName (using code from Example
8.7 on my site), you could then do something like this (assuming that the
name is stored in a variable called userName):

ActivePresentation.Slides(22).Shapes("TheName").TextFrame.TextRange _
   .Text = userName
