Hi Hajo,
Iām sorry for my misunderstanding 
When you add a report slide, it has a Review Course button. This button allows you to go back to the first slide after completing the quiz to help you follow and review all graded questions.
You can add events - actions - conditions to this button as follows:
With the setup like this, there are two possible cases:
-
If learners fail the conditions, when they click on this button, the presentation will go to the first slide to let them review their answers.
-
If learners pass the conditions, when they click on this button, the presentation will go to the next slide.
Regards,
Yen
