hello @Arthur378
in short, my suggestion back then was to leave the normal randomized content block which would add multiple questions in random order, and at the end, add a “submit all my responses” button:
for the “submit all button” you can use this html code:
<a href="#"><input class="check-all" type="button" value=" Submit all my responses"
onclick="$('div.submit-attempt-container button').each(function(){$(this).click()});">
I hope it helps
