Ummmmm sorry, but my imagination just failed me.. This is a quiz that you can't open until you answer the question correctly? How do you see that working?
No, I am not trying to be facetious, I just not sure what it is that you are actually asking. Do you mean that the users research a topic, develop some questions, and if a question they write matches a question in the quiz the entire quiz opens for them? Or they write a series of answers and if one matches a question in a quiz, the quiz then opens?
Or, do you want them to do something particular before they get to view the quiz? If so then you may find an answer by restricting activities.
