To link to a quiz, you have two options:

The POPlink is the easiest method because the page is already built, and you can just copy your POPlink to use it. See instructions here.

To use a dedicated quiz page, you'll add your quiz to a page and then link to that page. You can add a quiz to any page with either a page section (easier) or a code snippet (advanced but flexible).
