Can we blocked a quiz for one try ?

Hi,

I have a quiz I published in our LMS platform and I would like blocked it after the learners did it once. I have created my quiz with a question bank.

I would like to know if with Storyline 2 we can authorize the learner to do the quiz only one time ?

I tried different things :

- In the parameters lector / others / restart, I put "never restart"

- I put for all the slides the parameter "restart at the recorded state"

But it doesn't work...

Every time I relaunch the quiz in the platform, I can restart the quiz and have a new score.  

If somebody can help me, I'll appreciate.

Thanks

Laetitia
