Overall, I'm looking to create a website where the user needs to pass a little quiz to see each additional level of content (and ought never have to quiz again for each higher level). He/she will see the first level of content without any kind of registration.
Google Forms can handle registration, but is this information then readable to a website, and how (or does that not work)? Google forms can of course handle quiz questions, but then how would the results of the user passing be read by the website to determine display, or is Google Forms simply not designed for this?
