Not exactly.
I mean: if you passed the quiz number 1 of a category, I don't want to see it as playable again because I've already done it.
In my website I have 9 quizzes, so I want to force to solve others, after passed quiz number 1.

Hello,
Do you mean not letting the user play the Quiz second time, if he has already played it once? If this is what you mean then yes It's possible you can change the options for this on Add / Edit Quiz layout in Access settings Tab.

It's possible to lock user's access to a quiz 100% solved by the same user?
(e.g. by also changing the category image)
