Quiz trigers

Hello,

I am trying to do a multiple quiz training in which a have a series of tabs on the top. these tabs will direct you to different modules. The thing is that I want the tabs to be disable until the user passes the previous modules quizzes. for example, I have four modules and an introduction. before the user can access the first module I want them to go and watch the whole intro. after they complete the intro I want the module one to be enabled. after this they will go and finish the module and the quiz at the end. if they pass the quiz I want the module two to get enabled and so on. How can I do that?

The tabs layout and the different triggers (hover, selected, visited, and disabled) are already in a Slide Master. 

I will very much appreciate an answer.

Thank you
