Hello,
"ARI Quiz" provides access to all quizzes results only on backend. Registered users can see only own results on frontend, but you can submit a feature request
here and we will implement this feature in a future release or if you need this functionality urgently, we can implement it as a custom development.
You can read about upgrade from "ARI Quiz Lite" to "ARI Quiz"
here (see question #7). In brief, all data from "ARI Quiz Lite" will be available in "ARI Quiz" after upgrade.
Regards,
ARI Soft
