Quiz Form: How can we redirect the users to different pages of the form based on their score?

If the user fails the test, I would like the page to say "sorry, your failed, please re-teke the test" and the next button (could I change this one "next" button to say "re-take test") would send them back to the start of the form, or at least to the start of the questions. (side question-is it possible to have their info saved in all the fields so they dont have to re-fill all of their information?)

If they pass, I want them to be able to download their certificate and then press next to see the end of the form with a thank you and a submit. The submit would then send their info back to us letting us know that they are in-fact certified.

I can see based on my colleague's response on the other thread that you're calculating a final score based on the answers the users select. 

I think it will not be possible to implement what you want exactly as you described, but you can show a message based on their score and ask them to fill the form again if they fail the test. 

With conditions you can show hide fields and disable the submit button, this way they cannot submit the form if they do not pass the test. 

These guides will help you with the show/hide conditions and disabling fields:

You can also allow your users to save their data and continue filling the form later on:

Once they pass the test and submit the form they will get a thank you message and you can send them the desired files through an email auto-responder. 

I hope this helps. 

Thank you, this works perfectly! you guys are great!
