Session counts?

hi,

here is the problem.

A flash swf document has 12-14 scenes.
the last one being a final Quiz.

how to disable this last scene till it will be known that all slides have been browsed?

I need this for my e-learning so that people will not skip to the quiz straight away.

is there a way to let flash count during this spesific session that user has gone thorugh each and every slide, or at least “major ones”???
