Hi,
Return to quiz takes user to the last unattempted or incorrcect question slide, if you want to change this behavior you can use advance actions but it may not cover all the use cases. From the above description I can understand that you dont want to return to a missed question but use remediation only on incorrect question.
For this define a variable a = 0
set failure action of quiz slide as "Assign a =1"
now where you have defined return to quiz action, change it to conditional action
If a = 0 cotinue
else
return to quiz
Assign a =0
so if user has missed the quiz a will be 0 hence return to quiz will not occur. Please inform if you need more help on this as I am not aware of your course structure.
Regards,
