Help with Quiz slides
I have two queries regarding a quiz.
BACKGROUND: There are nine questions which the user needs to answer correctly to pass. If they answer any incorrectly they will need to retake the quiz.
1) Firstly how can I set the first 8 slides to just have buttons 'next' and 'back' and the 'submit all' button to be on the final question slide only? At the moment all slides have the three buttons. I cannot delete it from the individual slides and if I attempt to delete it from the master slide I assume it will delete from all 9 slides. See screen grab below.

2) Secondly when all questions are answered the user receives the screen below.
• When all are answered correctly I would like there to be no options other than a screen showing 'Congratulations, 100% correct' (or somthing similar). Then the quiz closes down or an exit button perhaps.
• If there are any incorrect answers I would like there to be just a 'retake quiz' button, not a continue. How can I achieve this?

I have set the reporting to pass 100% so I think this concerns the settings and the UI and any help would be amazing.
Thank you in advance.
