Sorry, I was not clear enough. There are various "settings" places for a quiz, this can be confusing. Here we go again:
- In your Moodle course, click on the name of a quiz;
- In the top right corner, click on the "cogwheel" to open the Actions menu
- The filters link appears near the bottom
That's for Moodle 3.9 latest with the default theme. It may look different on your own Moodle site...
