Hi Ula,
there is no “copy” function. You cannot copy quiz settings from one quiz to another.

However, HD Quiz uses something called “custom post templates”, which means that HD Quiz works similar to a blog in that Quizzes are like categories, and questions are like posts. Because of this, you can actually reuse questions and attach them to multiple quizzes.

STEPS

• Create a new quiz
• Go to HD Quiz ⇾ tools, and select the Questions Custom Post Type Admin tool
  • You will now see a list of all of your questions in a native WordPress page
• From the Quizzes column, select the quiz you wish to “duplicate”. This will now only show you questions attached to that quiz
• From here, you can select all the questions, and then the Bulk Actions dropdown ⇾ bulk edit ⇾ apply, and select the new quiz
• Update to save. Now you’ve added all the same questions to the new quiz
• (bonus) on the top right is a ribbon called Screen Options. Select this and update “Number of items per page” to something larger like 100. This will make it easier/faster to add all of your questions to the new quiz at once

I hope the above is useful to you.

If you want to force all quizzes to have the exact same settings, this is possible as well by adding some code to your site. To learn more about this, you can read this previous thread where I outline everything
